News Behind 2023 Prelims PYQ

Why This Question Was Asked

In 17 Dec 2022, One million winged visitors expected this season to Kolleru lake in AP put Kolleru Kanwar lakes in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

The correct answer is A: Only one. The paper used a new "pairing" style format. Based on geographical facts, only Statement 1 is unequivocally correct. Statement 2 is incorrect because the Krishna River does not directly feed Kolleru Lake; rather, the lake is located between the Krishna and Godavari deltas. Statement 3 is technically incorrect in the context of the Gandak River; while Kanwar Lake is an oxbow lake formed by river meandering, it was formed by the Burhi Gandak, which is a distinct palaeochannel/tributary, not the main Gandak River. Thus, only one statement is fully accurate.

Statement 1: Jhelum River passes through Wular Lake.

• Correct.
  • Explanation: The Jhelum River, a major tributary of the Indus, flows into Wular Lake (one of the largest freshwater lakes in Asia) in the Bandipora district of Jammu and Kashmir and exits it. Wular Lake acts as a natural reservoir for the river, helping to regulate its flow. This is a standard geographical fact regarding the drainage system of North India.

Statement 2: Krishna River directly feeds Kolleru Lake.

• Incorrect.
  • Explanation: Kolleru Lake, located in Andhra Pradesh, is a freshwater lake situated between the deltas of the Krishna and Godavari rivers. It is fed by seasonal tracks like Budameru and Tammileru. It does not receive a direct feed from the main channel of the Krishna River. This is a common distractor because students often associate the lake's location with the Krishna-Godavari basin without verifying the specific inflow sources.

Statement 3: Meandering of the Gandak River formed Kanwar Lake.

• Incorrect.
  • Explanation: Kanwar Lake (Kanwar Taal) in Bihar is indeed an oxbow lake formed by the meandering of a river. However, the river responsible is the Burhi Gandak (Old Gandak), not the main Gandak River. In geomorphology, the distinction between the main river and its palaeochannels (like Burhi Gandak) is crucial. The Burhi Gandak flows parallel to the Gandak and is known for its high sinuosity and tendency to form oxbow lakes.

Option A: Only one

• Correct. Since only Statement 1 is factually accurate, this is the correct choice.

Option B: Only two

• Incorrect. This option assumes two statements are correct. A common mistake is to assume Statement 3 as correct because they overlook the "Burhi" prefix in the river name.

Option C: All three

• Incorrect. This option is for candidates who have a general but imprecise understanding of river-lake associations in India.

Option D: None

• Incorrect. Since Statement 1 is a well-documented geographical fact, this option is eliminated.

Key Takeaway

The core concept tested is the relationship between river dynamics and lake formation (Drainage System). It highlights the importance of precision in geographical nomenclature (e.g., distinguishing between Gandak and Burhi Gandak) and specific hydrological connections.

Correct Answer: A

Option A follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

When Mundra port pairs was reported, it made Mundra port pairs a live current-affairs theme for Prelims.

Analysing the Question

Option B (Only two pairs)

. This means that out of the three statements provided, exactly two are factually accurate, while one contains an error regarding the categorization of Indian ports.

Pair 1 is Correct

Kamarajar Port (formerly Ennore Port), located in Tamil Nadu, is indeed the first major port in India to be incorporated as a company under the Companies Act. While other major ports are governed by the Major Port Authorities Act (formerly the Major Port Trusts Act, 1963), Kamarajar Port functions as a corporate entity.

Pair 2 is Correct

Mundra Port, located in the Kutch district of Gujarat, is the largest privately owned port in India. It is owned and operated by Adani Ports and Special Economic Zone Limited (APSEZ). It has surpassed several government-owned ports in terms of annual cargo handling capacity.

Pair 3 is Incorrect

Visakhapatnam Port is a major port on the east coast, known for being a natural harbor and handling iron ore, but it is not the largest container port in India. The title of the largest container port belongs to Jawaharlal Nehru Port (JNPT) in Navi Mumbai, Maharashtra.

Option A: Only one pair

• Incorrect.
• This option would be correct if only one statement were true. However, since both Kamarajar Port's corporate status and Mundra Port's private ownership status are factual, this option underestimates the correct count.

Option B: Only two pairs

• Correct.
• As established, Pair 1 and Pair 2 are accurate descriptions. Pair 3 is factually wrong because it misidentifies the primary function/rank of Visakhapatnam Port. Therefore, exactly two pairs match.

Option C: All three pairs

• Incorrect.
• This is a common distractor for candidates who know Visakhapatnam is a "major" port but fail to distinguish between types of cargo. Visakhapatnam is a premier port for bulk cargo and iron ore, but in the specific category of containers (TEUs), JNPT (public) and Mundra (private) are far ahead.

Option D: None of the pairs

• Incorrect.
• This option is incorrect as it ignores the well-established facts regarding the corporatization of Ennore (Kamarajar) and the scale of the Mundra Port.

Detailed Analysis of Incorrect Pair 3

• The Error: Visakhapatnam is often called the "Bright Star of the East Coast" and is India’s deepest landlocked port, but Jawaharlal Nehru Port Trust (JNPT) handles over 50% of India’s total container traffic among major ports.
• **Exam trap: ** UPSC often swaps the "superlatives" of similar geographical features (e.g., swapping the largest container port with the largest natural harbor) to test the candidate's precision in data.

Correct Answer: B

In the context of Indian infrastructure, remember that Kamarajar is the only "corporate" major port, Mundra is the private leader, and JNPT is the container king. Visakhapatnam is significant for its depth and bulk cargo (iron ore) rather than container volume.

Why This Question Was Asked

When Congo cobalt batteries was reported, it made Congo cobalt batteries a live current-affairs theme for Prelims.

Analysing the Question

Specifically, option C (The Democratic Republic of the Congo) is correct. The Democratic Republic of the Congo (DRC) is the world’s largest producer of cobalt, accounting for roughly 70% to 75% (about three-fourths) of global production.

Cobalt is a critical raw material for the cathode of lithium-ion batteries used in electric vehicles (EVs) and portable electronics because of its high energy density and stability. In 2022-23, the DRC produced over 130,000 metric tonnes of cobalt. The extraction is concentrated in the Copperbelt region of the Lualaba and Haut-Katanga provinces. The dominance of the DRC in this sector is a significant point of discussion in international geopolitics and supply chain ethics, frequently appearing in reports by the International Energy Agency (IEA) and the World Bank.

Option A: Argentina

• Incorrect.
  • Reasoning: While Argentina is a critical player in the "green energy" transition, its strength lies in Lithium, not Cobalt. Argentina, along with Chile and Bolivia, forms the "Lithium Triangle," holding the world's largest lithium brine reserves. This is a common distractor because students often confuse the various minerals required for EV batteries.

Option B: Botswana

• Incorrect.
  • Reasoning: Botswana is a major global producer of Diamonds (by value) and has significant reserves of copper and nickel. While it has some cobalt as a byproduct of nickel mining, its output is negligible compared to the DRC. It is included as a distractor because it is a prominent African mining economy.

Option C: The Democratic Republic of the Congo

• Correct.
  • Reasoning: As established by the United States Geological Survey (USGS), the DRC dominates the global cobalt market. It holds approximately 50% of the world’s known cobalt reserves and currently supplies approximately three-quarters of the global demand. This concentration makes the global EV industry highly dependent on the DRC’s political stability and mining regulations.

Option D: Kazakhstan

• Incorrect.
  • Reasoning: Kazakhstan is the world’s leading producer of Uranium (producing over 40% of global supply) and is rich in chromium and copper. While it is a major mineral exporter in Central Asia, it is not a primary source of cobalt. UPSC adds this to test the candidate’s ability to differentiate between leaders of various strategic "critical minerals."

Correct Answer: C

The Democratic Republic of the Congo (DRC) is the undisputed global leader in Cobalt production, supplying three-fourths of the world's demand, a fact essential for the global transition to Electric Vehicles (EVs).

Why This Question Was Asked

In 29 Jan 2023, New genus of wasp named after Soliga community in Karnataka put Seshachalam BR Hills in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Correct Answer Analysis: D (None)

The correct answer is D because all three statements provided are geographically incorrect. In the UPSC Prelims, map-based questions often test precise locations and the relative orientation of physical features. In this case, the question incorrectly associates specific hill ranges with major mountain systems (Vindhyas, Satpuras, Western Ghats) that are hundreds of kilometers away from their actual locations.

Option A: Only one

• Incorrect.
  • This option suggests that at least one of the statements is factually sound. However, as per the geological and geographical mapping of India, Statements 1, 2, and 3 are all demonstrably false.

Option B: Only two

• Incorrect.
  • This is a common distractor for candidates who might correctly identify one error but harbor confusion about the other two. None of the listed claims meet the criteria for geographical accuracy.

Option C: All three

• Incorrect.
  • This option is incorrect as every statement contains a fundamental factual error regarding the placement of Indian hill ranges.

Option D: None

• Correct.
  • Statement 1 Analysis: Amarkantak Hills are located at the junction of the Vindhya and Satpura ranges (specifically the Maikal range), not the Sahyadri (Western Ghats). The Sahyadris are situated along the western coast, far from Central India.
  • Statement 2 Analysis: Biligirirangan Hills (BR Hills) are located in Karnataka and act as a bridge between the Western Ghats and the Eastern Ghats. They have no connection to the Satpura Range, which is located much further north in Central India (Madhya Pradesh/Maharashtra).
  • Statement 3 Analysis: Seshachalam Hills are located in Andhra Pradesh and are part of the Eastern Ghats. The southernmost part of the Western Ghats is generally considered to be the Cardamom Hills or the Anaimalai/Nilgiri complex. Seshachalam is famous for Tirupati and its Red Sanders forests, both situated on the eastern side of the peninsula.

Key Takeaway

This question tests the candidate's ability to distinguish between the major mountain systems of Central India (Vindhya/Satpura) and Peninsular India (Western/Eastern Ghats). Success depends on knowing the specific states where these hills are located and their relative positions on the Indian map.

Correct Answer: D

Option D follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

When Marsupial smuggling India was reported, it made Marsupial smuggling India a live current-affairs theme for Prelims.

Analysing the Question

Option C is correct because Statement-I is a factual truth regarding biogeography, while Statement-II is a factually incorrect generalization regarding ecology.

Statement-I is Correct

Marsupials are a group of mammals characterized by giving birth to relatively undeveloped young, which then reside in a pouch. Naturally, they are predominantly found in Australasia (Australia, New Guinea, and nearby islands) and the Americas. Due to continental drift and the isolation of the Indian plate following the breakup of Gondwana, marsupials are not indigenous to the Indian subcontinent. India’s mammalian fauna consists primarily of placental mammals.

Statement-II is Incorrect

The claim that marsupials can thrive only in montane grasslands with no predators is an extreme and scientifically inaccurate statement. Marsupials are highly diverse and inhabit a wide range of ecosystems, including tropical rainforests (Tree-kangaroos), arid deserts (Red Kangaroos), and temperate forests (Opossums). Furthermore, they coexist with various predators (such as Dingoes, Tasmanian Devils, and birds of prey); they do not require a predator-free environment to survive.

Option A: Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I

• Incorrect.
  • Error: This option assumes Statement-II is a scientific fact. In UPSC exams, statements using absolute qualifiers like "only" are frequently incorrect. Marsupials are not restricted to one specific habitat (montane grasslands), nor are they restricted to predator-free zones. Therefore, it cannot serve as an explanation for their absence in India.

Option B: Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I

• Incorrect.
  • Error: While Statement-I is true, this option is wrong because it validates Statement-II. UPSC often uses this as a distractor for candidates who might recognize Statement-I as true but are unsure about the specific habitat requirements of Australian fauna.

Option C: Statement-I is correct but Statement-II is incorrect

• Correct.
  • Verification: Statement-I correctly identifies the geographical distribution of marsupials. Statement-II fails because it ignores the ecological adaptability of marsupials (found in forests, plains, and deserts) and the reality of natural selection/predation in their native habitats.

Option D: Statement-I is incorrect but Statement-II is correct

• Incorrect.
  • Error: This is factually reversed. There is no fossil or historical evidence of extant marsupials being native to India. Conversely, the "only" condition in Statement-II makes it biologically impossible, as no major class of animals is restricted to such narrow parameters.

Correct Answer: C

The geographical distribution of species (Biogeography) is determined by plate tectonics and evolution, not just habitat type. Beware of extreme qualifiers like "only" in ecological statements, as most species are adapted to diverse environments and predator-prey dynamics.

Why This Question Was Asked

In 4 Jun 2022, Worst invasive species among plants used for tank beautification in Coimbatore  put Invasive species ISSG in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option A is correct because the Invasive Species Specialist Group (ISSG) is a global network of scientific and policy experts under the aegis of the Species Survival Commission (SSC) of the International Union for Conservation of Nature (IUCN).

The ISSG was established with the specific mandate to reduce the threats posed by invasive alien species to terrestrial, freshwater, and marine ecosystems. It manages and maintains the Global Invasive Species Database (GISD), which provides evidence-based information on alien species that negatively impact biodiversity and ecosystems. The ISSG’s work is essential for monitoring progress toward international targets, such as the Kunming-Montreal Global Biodiversity Framework (specifically Target 6 regarding invasive species).

Option A: The International Union for Conservation of Nature

• Correct.
  • The IUCN operates through six specialized commissions. The Species Survival Commission (SSC) is the largest of these, and the ISSG is one of its most prominent specialist groups. The ISSG provides the scientific rigor required to categorize "invasive" status, similar to how other SSC groups contribute to the IUCN Red List of Threatened Species.

Option B: The United Nations Environment Programme

• Incorrect.
  • Reasoning: While UNEP deals with global environmental policy and hosts the Secretariats of various conventions (like the CBD), it does not directly manage the ISSG or the GISD. UPSC includes UNEP as a distractor because it often collaborates with IUCN on global biodiversity reports, leading students to confuse the administrative oversight of specific databases.

Option C: The United Nations World Commission for Environment and Development

• Incorrect.
  • Reasoning: Also known as the Brundtland Commission, this body is famous for the 1987 report "Our Common Future," which defined "Sustainable Development." It is a defunct commission of the past and does not maintain active biological databases or specialist groups. It is included to test the candidate’s knowledge of historical environmental milestones versus active scientific bodies.

Option D: The World Wide Fund for Nature

• Incorrect.
  • Reasoning: WWF is an international non-governmental organization focused on conservation and reducing the human footprint on the environment. While WWF uses data from the GISD for its conservation projects (like the Living Planet Report), it is not the institutional home of the ISSG. UPSC uses WWF as a distractor because it is a high-profile conservation body often associated with species protection.

Key Takeaway:

The Invasive Species Specialist Group (ISSG) and its Global Invasive Species Database (GISD) are hosted by the IUCN’s Species Survival Commission (SSC). In UPSC exams, specific databases and specialist subgroups are frequently linked to the IUCN, which serves as the world’s primary authority on the status of the natural world.

Correct Answer: A

Option A follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

In 27 Mar 2023, Two held for poaching pregnant sambar deer put Lion-tailed macaque in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option A (Only one)

is the correct answer. The classification of an animal’s activity period is determined by its biological rhythm. Among the three species mentioned, only the Malabar Civet is strictly nocturnal.

• Malabar Civet (Viverra civettina): This is a critically endangered mammal endemic to the Western Ghats of India. It is famously elusive and strictly nocturnal, meaning it is most active after sunset and spends the daylight hours hidden in dense thickets.
• Lion-tailed Macaque (Macaca silenus): This primate is diurnal, meaning it is active during the day. It spends nearly 99% of its time in the forest canopy searching for fruits and insects during daylight hours.
• Sambar Deer (Rusa unicolor): While Sambar deer are often described as crepuscular (active during dawn and dusk), they are biologically categorized as having flexible activity patterns. However, in the context of "generally nocturnal" or "most active after sunset," they do not fit as neatly as the Malabar Civet because they are frequently active during the day, especially in protected areas where they feel safe from predators. In standard ecological classification for this type of question, only the Civet is the definitive nocturnal species.

Option A: Only one

• Correct.
  • Only the Malabar Civet is confirmed as a strictly nocturnal species. This option is correct because the other two (Lion-tailed Macaque and Sambar Deer) do not primarily fall under the "nocturnal" category. The Macaque is purely diurnal, and the Sambar is categorized as crepuscular/diurnal in most standard biological texts.

Option B: Only two

• Incorrect.
  • This is a common distractor because A common mistake is to assume the Sambar Deer for being nocturnal. While Sambar may show increased activity at night in areas with high human disturbance (anthropogenic pressure), they are not biologically classified as nocturnal animals. UPSC includes this to test if the candidate can distinguish between "behavioral adaptation to avoid humans" and "inherent biological traits."

Option C: All three

• Incorrect.
  • This is incorrect because the Lion-tailed Macaque is a primate. Almost all Old World monkeys (excluding a few like the Night Monkey of the New World) are strictly diurnal. Including the Macaque in the nocturnal category is a fundamental biological error.

Option D: None

• Incorrect.
  • This is incorrect because the Malabar Civet is an established nocturnal species. Known as one of the world's rarest mammals, its nocturnal nature is one of its most cited characteristics in Wildlife Conservation Society (WCS) and IUCN Red List data.

Correct Answer: A

This question tests the candidate's specific knowledge of Ethology (animal behavior) and endemic Indian fauna. In UPSC, remember: Macaques (monkeys) are diurnal, while Civets and Lorises are typically nocturnal.

Why This Question Was Asked

In 11 Mar 2023, Unlocking secrets of the honeybee dance language put Honeybee waggle dance in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Correct Answer Analysis: Honey Bees (Option C)

The "waggle dance" is a sophisticated form of communication used by honey bees (Apis mellifera) to share information about the location of food resources (pollen and nectar). This behavior was famously decoded by the Austrian ethologist Karl von Frisch, who was awarded the Nobel Prize in Physiology or Medicine in 1973 for his research on honey bee communication.

The dance conveys two critical pieces of data:

1. Direction: The angle of the bee’s movement relative to a vertical line on the honeycomb represents the angle of the food source relative to the position of the sun.
2. Distance: The duration of the "waggle" phase (the shaking of the abdomen) is proportional to the distance of the food source from the hive. A longer duration indicates a greater distance.

This is considered one of the most complex non-human communication systems in the animal kingdom, as it involves the use of displacement (referring to something not currently present) and symbolic representation.

Option A: Butterflies

• Incorrect.
  • Butterflies generally do not exhibit social structures complex enough to require collective foraging communication. They are primarily solitary foragers. While they use chemical signals (pheromones) for mating and visual cues to find flowers, they do not perform a coordinated dance to lead others to food. UPSC includes this because butterflies are well-known pollinators, often confused with bees in terms of behavioral complexity.

Option B: Dragonflies

• Incorrect.
  • Dragonflies are predatory insects. Their hunting strategy is based on individual aerial maneuvering and vision rather than social cooperation. They do not share food sources with a colony or "kin" in any organized manner. They are distantly related to the Hymenoptera order (which includes bees) and lack the social evolutionary drivers for communication like the waggle dance.

Option C: Honey Bees

• Correct.
  • The waggle dance is a unique, species-specific behavior characteristic of social honey bees. It allows the colony to efficiently exploit resources by recruiting "forager" bees to high-quality patches of flowers discovered by "scout" bees. This collective intelligence is a hallmark of eusocial insects.

Option D: Wasps

• Incorrect.
  • While wasps belong to the same order as bees (Hymenoptera) and some species are social (like hornets or yellowjackets), they do not use a "waggle dance" to communicate distance and direction of food. Wasps typically use chemical trails (pheromones) or visual recruitment, but they lack the symbolic "sun-angle" map used by honey bees. UPSC includes wasps as a distractor because they are biologically related to bees and share some social characteristics.

Key Takeaway

The waggle dance is a symbolic communication system unique to honey bees used to translate the sun's position and foraging distance into a directional "map" for the colony. It represents an advanced evolutionary adaptation for social cooperation in resource gathering.

Correct Answer: C

Option C follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

In 21 Nov 2020, Explained: The mystery of the glowing mushrooms in Meghalaya put Glowing mushrooms Meghalaya in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

The correct option is D: All four. This question tests the diverse functional and biological roles of fungi (mushrooms) in the ecosystem. In recent years, UPSC has shifted towards "broad possibility" questions in Science and Environment. Since mushrooms belong to an incredibly diverse kingdom (Fungi) with over 140,000 identified species, it is scientifically sound that "some" species would exhibit specialized properties like bioluminescence, toxicity to insects, or psychoactive effects.

Option A: Only one

• Incorrect.
  • This is incorrect because it underestimates the biological versatility of fungi. If a student only knows about edible or medicinal mushrooms, they might select this, but modern biology confirms all four traits exist in the fungal kingdom.

Option B: Only two

• Incorrect.
  • This is a common distractor for candidates who are aware of medicinal and psychoactive mushrooms (due to their presence in mainstream culture) but are unaware of the niche ecological traits like bioluminescence or insecticidal properties.

Option C: Only three

• Incorrect.
  • This suggests that one of the four properties is missing in nature. However, scientific evidence confirms that multiple species carry out each of these functions.

Option D: All four

• Correct.
  • Statement 1 (Medicinal): Many mushrooms are used in traditional and modern medicine. Examples include Ganoderma lucidum (Reishi), Lentinula edodes (Shiitake), and Cordyceps, which are known for immune-boosting and anti-inflammatory properties.
  • Statement 2 (Psychoactive): Certain mushrooms contain hallucinogenic compounds like psilocybin and psilocin. The genus Psilocybe (commonly known as "magic mushrooms") is the most well-known example.
  • Statement 3 (Insecticidal): Entomopathogenic fungi act as natural insecticides. Species like Beauveria bassiana and Cordyceps infect and kill specific insects, and they are often used in organic farming as bio-pesticides.
  • Statement 4 (Bioluminescent): Over 100 species of mushrooms are known to glow in the dark due to a chemical reaction involving the enzyme luciferase. Examples include Omphalotus olearius (Jack-o'-lantern mushroom) and Mycena chlorophos.

Correct Answer: D

In UPSC Prelims, statements starting with "some" regarding biological species are usually correct because of the vast biodiversity on Earth; it is highly probable that at least a few species out of thousands will possess a specific biological trait.

Why This Question Was Asked

In 22 Apr 2023, Microbes at the top of the world put High-altitude microbes in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option C (All three)

. This question tests the understanding of Extremophiles—microorganisms that have evolved to thrive in conditions that would be lethal to most life forms. In the field of astrobiology and microbiology, these organisms demonstrate the vast resilience and adaptability of life.

1. Statement 1 is correct: Certain microorganisms, known as hyperthermophiles, can survive and reproduce at temperatures exceeding 100°C (the boiling point of water). For example, Methanopyrus kandleri has been observed to grow at 122°C in hydrothermal vent environments under high pressure, which prevents the water from turning into steam.
2. Statement 2 is correct: Psychrophiles (cold-loving microbes) can grow at temperatures below 0°C (the freezing point of water). These organisms are found in deep-sea sediments, permafrost, and glaciers. For instance, Planococcus halocryophilus can remain metabolically active at -15°C to -25°C by utilizing specialized enzymes and "antifreeze" proteins.
3. Statement 3 is correct: Acidophiles thrive in environments with extremely low pH levels. Organisms like Picrophilus oshimae and Picrophilus torridus can grow at a pH of 0 or even lower (highly acidic), such as in volcanic soils and acid mine drainage.

Option A: Only one

• Incorrect.
  • This option would be chosen if a student only knew about one category of extremophiles (e.g., those in hot springs). However, extreme survival is a well-documented phenomenon across temperature and pH scales.

Option B: Only two

• Incorrect.
  • This is a common "trap" for students who might believe life is possible in extreme heat and acidity but assume that freezing point (0°C) is an absolute barrier for biological growth. In reality, sub-zero biological activity is common in Arctic and Antarctic ecosystems.

Option C: All three

• Correct.
  • Scientific empirical evidence confirms that life exists in all three conditions mentioned. Microbes have adapted to utilize chemicals for energy (chemosynthesis) and possess specialized cellular membranes that remain stable in extreme heat, cold, and acidity.

Option D: None

• Incorrect.
  • This contradicts fundamental biological knowledge taught in standard ecology and biology texts (like NCERT). UPSC includes this for candidates who might apply a narrow, "human-centric" view of habitable environments.

Key Takeaway

This question tests the concept of Extremophiles; life is not limited to "moderate" conditions and can thrive in temperature extremes (above 100°C and below 0°C) and chemical extremes (pH < 3).

Correct Answer: C

Option C follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

When Orangutan smuggling was reported, it made Orangutan smuggling a live current-affairs theme for Prelims.

Analysing the Question

Option B is correct. The Orangutan (Pongo) is a Great Ape known for its remarkable cognitive abilities and sophisticated tool use. Primatologists have observed Bornean and Sumatran orangutans using sticks for various purposes, particularly for extractive foraging.

They select specific twigs, strip the bark, and shape the ends to create a probe. This "tool" is used to scrape ants or termites from tree holes or to extract honey from beehives. In some habitats, they also use sticks to remove seeds from the Neesia fruit, which is covered in irritating stinging hairs. This behavior is a classic example of complex problem-solving and cultural transmission within primate populations, placing them alongside chimpanzees and humans in the category of sophisticated tool-users.

Option A: Fishing cat

• Incorrect.
  • The Fishing cat (Prionailurus viverrinus) is a medium-sized wild cat found primarily in South and Southeast Asia. While it has unique adaptations such as partially webbed feet for swimming and specialized hunting techniques to catch fish, it does not use tools. This is a common distractor because the Fishing cat is a high-priority conservation species in India (State animal of West Bengal), but its intelligence is expressed through specialized hunting reflexes rather than cognitive tool manipulation.

Option B: Orangutan

• Correct.
  • Orangutans are among the most intelligent primates. Their ability to manufacture and use tools (like sticks for probing) is a well-documented scientific fact. This trait distinguishes Great Apes from most other mammals. Their use of sticks to scrape insects from logs or tree holes is a primary example of their foraging strategy in the wild.

Option C: Otter

• Incorrect.
  • While some species, like the Sea Otter, use stones as "anvils" to crack open mollusks, they do not shape sticks to scrape insects from tree holes. Smooth-coated otters (common in India) are known for social cooperative hunting but not for the specific stick-probing behavior mentioned in the question. UPSC uses otters as a distractor because they are one of the few non-primates known for some form of tool use (using rocks), which might confuse a candidate who possesses only partial knowledge of tool-using animals.

Option D: Sloth bear

• Incorrect.
  • The Sloth bear (Melursus ursinus) is famous for eating termites and ants, but it uses physical adaptations rather than tools. It has long, curved claws to rip open logs and a specialized gap in its teeth (missing upper incisors) to "vacuum" up insects. It does not use sticks to scrape them out. It is a distractor because its diet (insects in logs) matches the scenario, but its method (suction/claws) does not involve tool-making.

Correct Answer: B

This question tests the candidate's knowledge of animal behavior and cognitive ecology. Among the options provided, only the Orangutan (a Great Ape) possesses the advanced fine motor skills and cognitive foresight required to manufacture and use a stick as a probe for foraging.

Why This Question Was Asked

In 3 Aug 2022, Union Cabinet approves India’s climate pledges put India UN climate pledges in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

The correct answer is Option (C): Only three.

Hydrofluorocarbons (HFCs) were introduced as a functional replacement for Ozone Depleting Substances (ODS) like Chlorofluorocarbons (CFCs) and Hydrochlorofluorocarbons (HCFCs) under the Montreal Protocol. While HFCs do not deplete the ozone layer, they are potent greenhouse gases with high Global Warming Potential (GWP), leading to their phasedown under the Kigali Amendment (2016).

According to various environmental agencies (EPA, UNEP) and the Technology and Economic Assessment Panel (TEAP), HFCs are extensively used in:

1. Aerosols: As propellants in products like metered-dose inhalers and hairsprays.
2. Foam agents: As blowing agents in the manufacture of insulation foams (polyurethane).
3. Fire retardants: Specifically in "clean agent" fire suppression systems for data centers or cockpits where water would damage equipment.

Lubricants (Point 4) are generally not made using HFCs; they typically utilize synthetic oils, petroleum, or silicones.

Option A: Only one

• Incorrect.
  • This option is incorrect because HFCs have more than one industrial application. As a distractor, this appeals to candidates who might only associate HFCs with the most famous application—refrigeration/air conditioning—and ignore their role in specialized sectors like medical aerosols or fire safety.

Option B: Only two

• Incorrect.
  • This is a common distractor because while many students know about HFCs in Aerosols and Foam agents, they often forget their specific use in the Fire Protection industry (halon alternatives). Missing even one of the three valid categories leads to this incorrect choice.

Option C: Only three

• Correct.
  • Specific HFCs (like HFC-134a, HFC-227ea, and HFC-245fa) are used in Aerosols, Foam blowing agents, and Fire retardants. The fourth item (Lubricants) is the outlier. In the UPSC context, this requires knowing the nuances of "Ozone-friendly" alternatives across different industries, not just the cooling sector.

Option D: All four

• Incorrect.
  • This is a "trap" option. Many candidates assume that versatile chemical groups like HFCs or CFCs are used in "everything" industrial. While HFCs are used as refrigerants, solvents, and the three mentioned above, Lubricants are distinct chemical formulations. Lubricant additives may contain fluorine (like PTFE), but they are not categorized under the HFC group managed by the Montreal Protocol.

Key Takeaway

HFCs are critical industrial chemicals used as propellants (Aerosols), blowing agents (Foams), and extinguishants (Fire Retardants), in addition to their primary role as refrigerants. They are targeted for phasedown under the Kigali Amendment due to their high Global Warming Potential.

Why This Question Was Asked

In 24 Mar 2023, Finance Bill 2023 was approved with amendments. Here are the highlights put InvIT tax Budget 2023 in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Statement-I is incorrect

and Statement-II is correct.

Statement-II is correct

In the Union Budget 2021-22, the government proposed amendments to the SARFAESI Act, 2002, to Recognize InvITs and Real Estate Investment Trusts (REITs) as 'borrowers'. This was done to enable Pooled Investment Vehicles to access debt finance from institutional investors and to allow lenders (like Banks and NBFCs) to use the recovery mechanisms under the SARFAESI Act in case of default.

Option A

(Both Statement-I and Statement-II are correct...) * Incorrect. * Statement-I is factually wrong regarding the tax treatment of InvIT distributions. Interest income is generally taxable for the unit-holders. UPSC includes this to test if candidates understand the "Pass-Through" status and the shift in dividend taxation rules in recent budgets.

Option B

(Both Statement-I and Statement-II are correct...) * Incorrect. * This is incorrect for the same reason as Option A; Statement-I contains a factual error regarding the exemption of interest income.

Option C

(Statement-I is correct but Statement-II is incorrect) * Incorrect. * This option is a complete reversal of the facts. Statement-I is wrong, and Statement-II is a factually documented legal amendment made to facilitate the ease of doing business and credit flow to the infrastructure sector.

Option D

(Statement-I is incorrect but Statement-II is correct) * Correct. * This is the only option that reflects the legal reality: InvIT interest distributions are usually taxable for investors, and InvITs have been formally brought under the ambit of the SARFAESI Act to strengthen the rights of lenders and promote Bond Market participation.

Key Takeaway:

InvITs act as "pass-through" entities where income (interest/dividend) is taxed at the investor's level rather than the trust's level in most cases. Additionally, to deepen the infrastructure debt market, InvITs are legally recognized as borrowers under the SARFAESI Act, 2002.

Correct Answer: D

Option D follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

When Fed rate hikes rupee was reported, it made Fed rate hikes rupee a live current-affairs theme for Prelims.

Analysing the Question

Option A is correct

because both statements are factually accurate and Statement-II provides the logical rationale behind the actions described in Statement-I.

• Factuality of Statement-I: In the post-COVID-19 recovery phase (specifically 2022-2023), global inflation surged due to supply chain disruptions, the pent-up demand (revenge spending), and the Russia-Ukraine conflict. In response, major central banks—including the U.S. Federal Reserve, the European Central Bank, and the Reserve Bank of India (RBI)—embarked on a synchronized cycle of interest rate hikes. For instance, the RBI raised the Repo Rate from 4.00% to 6.50% between May 2022 and February 2023.
• Factuality of Statement-II: Central Banks operate on the principle of Monetary Policy Transmission. They believe that by raising policy rates (interest rates), they increase the cost of borrowing and incentivize savings. This reduces the money supply and aggregate demand in the economy, which eventually cools down rising consumer prices (inflation).
• Logical Connection: Statement-II explains the "Why" behind Statement-I. The reason central banks carried out these hikes (the action) is their institutional mandate and belief that such monetary tools can effectively counteract inflation (the rationale).

Option A: Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I

• Correct.
  • This option accurately identifies that the rate hikes were a global phenomenon (Statement-I) and that these actions were driven by the fundamental economic theory that monetary policy is the primary tool to control inflation (Statement-II).

Option B: Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I

• Incorrect.
  • While both statements are true, saying Statement-II is not the explanation is wrong. Under the "Inflation Targeting" framework (common in India and the West), interest rate adjustment is the direct instrument used to fulfill the objective of price stability. UPSC uses this as a distractor to test if students understand the causal link between policy tools and economic goals.

Option C: Statement-I is correct but Statement-II is incorrect

• Incorrect.
  • Statement-II is a foundational principle of modern macroeconomics. Central banks worldwide are legally mandated (e.g., the RBI Act, 1934 in India) to maintain price stability using monetary policy. Claiming Statement-II is incorrect would negate the very purpose of a Central Bank’s existence.

Option D: Statement-I is incorrect but Statement-II is correct

• Incorrect.
  • Statement-I is a well-documented historical fact of the 2022-23 period. Mentioning it as incorrect ignores the global "Tight Monetary Policy" stance that dominated financial news during the post-pandemic recovery years.

Key Takeaway

Central Banks use hawkish monetary policy (raising interest rates) as a standard mechanism to curb inflation by reducing liquidity and dampening excessive demand in the economy.

Correct Answer: A

Option A follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

When Carbon markets explained was reported, it made Carbon markets explained a live current-affairs theme for Prelims.

Analysing the Question

Option B is correct because both statements are factually accurate, but Statement-II does not provide the logical reasoning or causal link for Statement-I.

Statement-I is correct

Carbon markets (both compliance and voluntary) are increasingly recognized as essential policy tools globally. Under Article 6 of the Paris Agreement, framework rules for international carbon trading were established, allowing countries to fulfill their Nationally Determined Contributions (NDCs) more cost-effectively. Large economies, including the EU (ETS), China, and recently India (via the Energy Conservation Amendment Act, 2022), are adopting these markets, making them "widespread tools" for decarbonization.

Statement-II is correct

In a carbon market, especially through "Cap-and-Trade" systems, the State/Government sets a limit on emissions and issues/auctions permits. When private entities buy these allowances from the government, financial resources are transferred from the private sector to the State. Furthermore, penalties for non-compliance are paid to the State.

• Why Statement-II is NOT the explanation: Statement-I focuses on the global prevalence and utility of carbon markets in fighting climate change. Statement-II describes a financial mechanism (resource transfer). Carbon markets are considered "widespread tools" because they provide a market-based incentive to reduce emissions and enable cost-efficient mitigation, not simply because they transfer money to the State. In fact, many carbon markets (like the Voluntary Carbon Market) involve transfers between private entities, not just to the State.

Option A: Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I

• Incorrect.
• While both statements are true, the logic is flawed. The "widespread" nature of carbon markets is due to their efficiency in achieving emission targets and fostering innovation. The transfer of resources to the State is a characteristic of specific carbon pricing models (like auctions), but it is not the reason why these markets are the primary tool against climate change.

Option B: Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I

• Correct.
• As established, Statement-I identifies the policy prominence of carbon markets, and Statement-II identifies a fiscal reality of government-led carbon trading (Cap-and-Trade). They are independent facts.

Option C: Statement-I is correct, but Statement-II is incorrect

• Incorrect.
• This is a common distractor for students who believe carbon markets only involve private-to-private trading (like the Clean Development Mechanism). However, in many national systems, the State generates significant revenue by auctioning carbon credits, effectively transferring private capital to the public treasury for climate-resilient infrastructure.

Option D: Statement-I is incorrect, but Statement-II is correct

• Incorrect.
• Statement-I is demonstrably true given the proliferation of carbon pricing initiatives worldwide (covering approximately 23% of global GHG emissions as of recent World Bank reports). Dismissing Statement-I ignores the central role of the Paris Agreement’s Article 6.

Correct Answer: B

Carbon markets are a cornerstone of modern climate policy because they internalize the "external cost" of pollution; while they do involve a transfer of resources from the private sector to the State (via auctions or fines), their primary value lies in incentivizing cost-effective emission reductions.

Why This Question Was Asked

In 8 Apr 2022, RBI moves to normalise liquidity, introduces SDF as the floor to absorb excess funds put RBI liquidity OMO SDF in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option A

is correct because Sterilization is a monetary policy tool used by the Reserve Bank of India (RBI) to manage the money supply and neutralize the impact of foreign exchange inflows or outflows on the domestic economy.

When the RBI intervenes in the foreign exchange market (e.g., buying US Dollars to prevent the Rupee from appreciating excessively), it injects an equivalent amount of Rupee liquidity into the banking system. This excess liquidity can lead to inflation. To "sterilize" or neutralize this effect, the RBI performs Open Market Operations (OMO) by selling government securities in the secondary market. This mops up the excess Rupees it had previously injected. Thus, OMO is the primary mechanism through which the RBI achieves sterilization.

Option A: Conducting 'Open Market Operations'

• Correct.
  • Sterilization refers specifically to the process of keeping the domestic money supply unchanged despite shocks from the capital account. Under the RBI Act, 1934, the central bank is empowered to conduct OMOs to regulate liquidity. This is a classic UPSC question focusing on the functional application of monetary instruments rather than just their definitions.

Option B: Oversight of settlement and payment systems

• Incorrect.
  • This refers to the RBI’s regulatory role under the Payment and Settlement Systems (PSS) Act, 2007. While the RBI oversees platforms like UPI, RTGS, and NEFT to ensure financial stability and efficiency, this activity has no direct link to the neutralization of foreign exchange impacts on the money supply. This is a distractor that focuses on the RBI's role as a "regulator" rather than a "monetary authority."

Option C: Debt and cash management for the Central and State Governments

• Incorrect.
  • This is a statutory obligation of the RBI under Sections 20 and 21 of the RBI Act (for the Centre) and via agreements (for States). While this involves managing the government's borrowing program and issuing T-Bills or "Ways and Means Advances," it is a fiscal agency function, not a "sterilization" activity aimed at balancing the external sector with domestic liquidity.

Option D: Regulating the functions of Non-banking Financial Institutions

• Incorrect.
  • The RBI regulates NBFCs under Chapter III-B of the RBI Act, 1934. This involves prudential norms, capital adequacy, and supervision to prevent systemic risk. This is a supervisory function and is entirely unrelated to the OMO-based liquidity management required for sterilization. UPSC includes this to test if the candidate can distinguish between "supervisory roles" and "monetary policy operations."

Key Takeaway:

Sterilization is the RBI's process of using Open Market Operations to offset the liquidity impact caused by foreign exchange interventions, ensuring domestic inflation remains stable despite global capital flows.

Correct Answer: A

Option A follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

When FPO Small Farmer Large Field was reported, it made FPO Small Farmer Large Field a live current-affairs theme for Prelims.

Analysing the Question

The concept of 'Small Farmer Large Field' (SFLF) is an innovative collective farming model designed to overcome the handicaps faced by small and marginal farmers, such as lack of economies of scale, low bargaining power, and poor access to technology.

Option B is correct because the SFLF model focuses on collective action while allowing farmers to retain their land ownership. In this model, farmers in a specific area organize themselves into groups (often coordinated by facilitators like NGOs or research institutes) to synchronize agricultural operations—such as land preparation, seeding, and harvesting. By harmonizing these activities, they effectively transform a collection of small, fragmented holdings into a "large field." This allows them to:

1. Purchase inputs (seeds, fertilizers) in bulk at lower costs.
2. Use modern machinery collectively.
3. Negotiate better prices with traders and processors due to larger volumes of uniform produce.

This model was successfully piloted in states like Odisha (specifically for rice) through collaborations between the International Rice Research Institute (IRRI) and local partners.

Option A

"Resettlement of a large number of people, uprooted from their countries due to war, by giving them a large cultivable land..." * Incorrect. * Reason: This describes a rehabilitation and resettlement scheme, which is a humanitarian and social initiative. While collective farming can be a part of resettlement, the SFLF is specifically a market-linked economic model aimed at existing resident marginal farmers to improve productivity, not a refugee resettlement program.

Option B

"Many marginal farmers in an area organize themselves into groups and synchronize and harmonize selected agricultural operations" * Correct. * Reason: This accurately captures the two pillars of SFLF: aggregation (organizing into groups) and synchronization (harmonizing operations). It targets the "dis-economies of scale" inherent in Indian agriculture, where over 86% of farmers are in the small/marginal category.

Option C

"Many marginal farmers in an area together make a contract with a corporate body and surrender their land to the corporate body..." * Incorrect. * Reason: This describes Corporate Farming or a form of land leasing. In SFLF, farmers never surrender their land or its management to a corporate entity. They remain the decision-makers. UPSC included this to test the student’s ability to distinguish between "group farming" and "corporate takeover."

Option D

"A company extends loans, technical knowledge and material inputs... so that they produce the agricultural commodity required by the company..." * Incorrect. * Reason: This is the definition of Contract Farming. While SFLF groups may engage in contract farming as a collective, the SFLF concept itself is about the internal organization of farmers to create scale, rather than the external relationship with a manufacturing company.

Correct Answer: B

The Small Farmer Large Field (SFLF) model is a participatory, community-based approach that enables marginal farmers to achieve economies of scale and better bargaining power without losing land ownership, by synchronizing their farming activities.

Why This Question Was Asked

When Nigerseed MSP kharif was reported, it made Nigerseed MSP kharif a live current-affairs theme for Prelims.

Analysing the Question

Option C (All three)

. This question tests the candidate's specific knowledge of oilseeds included under the Minimum Support Price (MSP) regime, cropping seasons, and the socio-economic practices of indigenous communities in India.

1. Factual Backing for Statement 1: The Government of India announces MSP for 22 mandated crops and Fair and Remunerative Price (FRP) for Sugarcane. Among the 7 oilseeds covered under MSP, Niger seed (Guizotia abyssinica) is significantly included. The Commission for Agricultural Costs and Prices (CACP) recommends the MSP for Niger seed based on the cost of production and market trends.
2. Factual Backing for Statement 2: Niger seed is primarily grown in India as a Kharif crop (sown with the onset of the monsoon). It is drought-tolerant and often grown in hilly or marginalized lands with poor soil fertility.
3. Factual Backing for Statement 3: Niger seed is a major source of edible oil for tribal populations, particularly in Odisha, Chhattisgarh, Madhya Pradesh, and Maharashtra. It is prized for its fatty acid profile and is a vital part of the tribal economy and diet.

Option A: Only one

• Incorrect.
  • This option is incorrect because more than one statement is factually true. UPSC often uses "Only one/two" options in its new formatting to prevent students from using the elimination method effectively, forcing a deeper level of factual certainty.

Option B: Only two

• Incorrect.
  • This is a common distractor. Students might be aware that Niger seed is a minor oilseed but may be unsure if it is actually covered under the MSP list or if it is specifically used by tribal communities for cooking (as opposed to industrial use). Since all three statements are true, "Only two" is incorrect.

Option C: All three

• Correct.
  • All three statements are verified facts.
    • Statement 1 is correct: Niger seed is one of the 14 Kharif crops for which MSP is announced.
    • Statement 2 is correct: Its cultivation cycle aligns with the Kharif season (June–October).
    • Statement 3 is correct: Tribal communities (like the Odias and various central Indian tribes) use it extensively for cooking oil and even as a condiment.

Option D: None of the above

• Incorrect.
  • This option would only be correct if all three statements were false. Given that the MSP list and cropping patterns are documented by the Ministry of Agriculture & Farmers Welfare, this option is easily discarded.

Key Takeaway

The UPSC regularly tests "minor" crops included in the MSP list (like Niger seed, sesamum, or ragi). For revision, remember that Niger seed is a Kharif oilseed supported by MSP and is a staple in the tribal agricultural economy of India.

Correct Answer: C

Option C follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

When 15th FC devolution criteria was reported, it made 15th FC devolution criteria a live current-affairs theme for Prelims.

Analysing the Question

Option B (Only three) is correct.

The 15th Finance Commission (XVFC), chaired by N.K. Singh, was tasked with recommending the tax devolution formula for the period 2021–26. For horizontal devolution (the distribution of the divisible pool of taxes among the states), the Commission used a total of six criteria.

The question asks for the criteria used other than Population, Area, and Income Distance. The following three criteria from the list provided in the question were used by the XVFC:

1. Demographic Performance (12.5% weight): Introduced to reward states that have made efforts to control their population (using the TFR concept).
2. Forest and Ecology (10% weight): Calculated based on the share of the state’s dense forest within the total dense forest of all states.
3. Tax and Fiscal Efforts (2.5% weight): Used to reward states with higher tax collection efficiency.

Therefore, out of the five items listed, only three (1, 2, and 5) serve as criteria for horizontal devolution.

Option A: Only two

• Incorrect.
  • This is incorrect because it misses one of the three valid criteria. A student might overlook "Tax and Fiscal Efforts," which has a relatively low weightage (2.5%), leading them to think only two criteria from the list apply.

Option B: Only three

• Correct.
  • As per the XVFC report, the criteria used are Demographic Performance, Forest and Ecology, and Tax and Fiscal Efforts. The other two traditional criteria mentioned in the question (Population and Income Distance) are excluded from the count per the question's specific phrasing.

Option C: Only four

• Incorrect.
  • This is incorrect because it includes a distractor. Often, students confuse the broader "Terms of Reference" (ToR) of the Finance Commission with the specific "Devolution Formula." While "Governance Reforms" may be discussed in the Commission's recommendations for grants, it is not a mathematical criterion for tax devolution.

Option D: All five

• Incorrect.
  • This is incorrect. Neither Governance Reforms (3) nor Stable Government (4) are used as indicators in the horizontal devolution formula. These are qualitative aspects or broad objectives of the Commission’s study but hold no weightage in the percentage-based distribution of tax revenue. UPSC includes these to test whether the candidate can distinguish between the formulaic criteria and general policy goals.

Correct Answer: B

To solve Finance Commission questions, differentiate between the horizontal devolution formula (Population, Area, Income Distance, Forest/Ecology, Demographic Performance, and Tax Effort) and the Commission’s general recommendations or grants-in-aid conditions. Only six specific metrics determine the tax share.

Why This Question Was Asked

When Prison management states was reported, it made Prison management states a live current-affairs theme for Prelims.

Analysing the Question

Option A is the correct answer because both statements are factually accurate, and Statement-II provides the historical and legal foundation for the administrative setup described in Statement-I.

Statement-I is Correct

In the Indian federal structure, "Prisons" and "Persons detained therein" are subjects under the State List (Entry 4 of List II) of the Seventh Schedule to the Constitution. Consequently, the administration and management of prisons, including the formulation of rules, regulations, and manuals for day-to-day operations, fall under the exclusive jurisdiction of the respective State Governments.

Statement-II is Correct and explains Statement-I

Modern prison administration in India is primarily governed by the Prisons Act of 1894. This colonial-era legislation expressly vested the control and management of prisons in the Provincial Governments (now State Governments). When the Constitution was drafted, this decentralised administrative logic was carried forward into the Seventh Schedule. Therefore, Statement-I (the current reality) exists because of the legal framework established by Statement-II (the Act and its historical delegation of power).

Option A: Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I.

• ✅ CORRECT. As explained above, the Prisons Act of 1894 is the parent legislation that decentralised prison management. By keeping prisons under "Provincial" control, it set the precedent for prisons becoming a State subject under the Constitution of India.

Option B: Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I.

• ❌ INCORRECT. This is a common distractor in UPSC "Assertion-Reason" style questions. While both statements are true, they are not independent of each other. Statement-II provides the legal "why" and "how" behind the practical "what" described in Statement-I. Ignoring the causal link between the Act and the current administrative status would be a logical error.

Option C: Statement-I is correct but Statement-II is incorrect.

• ❌ INCORRECT. This option assumes Statement-II is false. However, the Prisons Act of 1894 is indeed the extant law governing prisons in India. Students might confuse this by thinking a new central law has replaced it; while the Ministry of Home Affairs provides a "Model Prison Manual," it is merely advisory, and the 1894 Act remains the statutory authority.

Option D: Statement-I is incorrect but Statement-II is correct.

• ❌ INCORRECT. This option assumes Statement-I is false. A student might mistakenly believe that because "Criminal Law" is in the Concurrent List, prisons must also be a shared responsibility. However, the UPSC tests the distinction between Criminal Law/Procedure (Concurrent) and Prison Administration (State).

Key Takeaway:

Under the Seventh Schedule (Entry 4, List II), prison management is a State subject, a status rooted in the Prisons Act of 1894, which originally delegated the control of jails to Provincial Governments.

Correct Answer: A

Therefore, Statement-I (the current reality) exists because of the legal framework established by Statement-II (the Act and its historical delegation of power).

Why This Question Was Asked

In 14 Jul 2022, Centre yet to constitute 9th National Commission for Backward Classes  put NCBC constitutional body in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option A: Only one

.

In the Indian administrative framework, bodies are categorized as Constitutional (defined in the Constitution), Statutory (created by an Act of Parliament), or Executive (created by a government order). Among the four bodies listed, only the National Commission for Backward Classes (NCBC) is currently a constitutional body. It was granted constitutional status through the 102nd Constitution Amendment Act, 2018, which inserted Article 338B into the Constitution.

The other three organizations are either statutory bodies (created by law) or executive bodies (created by government resolution), and thus do not hold constitutional status.

1. The National Commission for Backward Classes (NCBC)

• ✅ CONSTITUTIONAL BODY
• Originally established as a statutory body in 1993, its status was elevated to a constitutional body in 2018. It falls under the Ministry of Social Justice and Empowerment and is empowered by Article 338B to investigate and monitor all matters relating to the safeguards provided for the socially and educationally backward classes.

2. The National Human Rights Commission (NHRC)

• ❌ NON-CONSTITUTIONAL (STATUTORY)
• The NHRC is a statutory body established on October 12, 1993, under the provisions of the Protection of Human Rights Act (PHRA), 1993.
• Why UPSC includes it: Students often confuse "powerful" or "national-level" bodies with constitutional ones. While it performs a sovereign function, its origin is a parliamentary statute, not a constitutional article.

3. The National Law Commission

• ❌ NON-CONSTITUTIONAL (EXECUTIVE)
• The Law Commission of India is neither a constitutional nor a statutory body. It is an ad-hoc executive body established by an order of the Government of India (Ministry of Law and Justice) for a fixed tenure (usually three years).
• Why UPSC includes it: Its name sounds highly formal and legal, leading aspirants to assume it is either statutory or constitutional. However, it exists purely through executive resolution.

4. The National Consumer Disputes Redressal Commission (NCDRC)

• ❌ NON-CONSTITUTIONAL (STATUTORY)
• The NCDRC is a quasi-judicial statutory body established in 1988 under the Consumer Protection Act, 1986 (now governed by the Consumer Protection Act, 2019).
• Why UPSC includes it: It is a top-tier judicial body for consumer grievances, but like various other tribunals and commissions, it is a product of legislation (statute), not the Constitution itself.

Option Analysis (Correct Answer Selection)

Option A (Only one)

✅ Correct. Only the NCBC is constitutional.

Option B (Only two)

❌ Incorrect. This would imply two bodies are constitutional, but three of the four are statutory/executive.

Option C (Only three)

❌ Incorrect.

Option D (All four)

❌ Incorrect.

Correct Answer: A

For UPSC, it is vital to distinguish between bodies created by Articles (Constitutional), Acts of Parliament (Statutory), and Government Resolutions (Executive). The 102nd Amendment Act is a frequent area of testing regarding the transition of the NCBC from statutory to constitutional status.

Why This Question Was Asked

In 8 May 2022, Value of vote of MPs likely to go down to 700 from 708 in July presidential elections put Presidential election vote value in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option D is correct

because all three statements provided in the question are factually and constitutionally incorrect.

Statement 1

is negated by Article 71(2) of the Indian Constitution, which protects the validity of acts performed by the President even if their election is later set aside.

Statement 2

is incorrect as per the Supreme Court’s ruling in the Presidential Poll Case (1974) and Article 62, which dictates that the election must be completed before the expiration of the term, regardless of dissolved assemblies.

Statement 3

is incorrect because Article 111 does not prescribe a specific timeframe for the President to grant or withhold assent, leading to the concept of the "Pocket Veto."

Correct Answer: D

The Indian President's office is built for administrative continuity: acts done remain valid after disqualification (Art 71), elections cannot be stalled by state-level vacancies (Art 62), and the Constitution provides no fixed deadline for granting assent to bills (Art 111).

Why This Question Was Asked

When Wildlife Amendment Act 2022 was reported, it made Wildlife Amendment Act 2022 a live current-affairs theme for Prelims.

Analysing the Question

The correct option is B (Only two). In the context of the Wildlife (Protection) Amendment Act, 2002, Community Reserves are a category of protected areas established on private or community lands where the community or an individual has volunteered to conserve wildlife.

Under the Act, once an area is notified as a Community Reserve, it falls under specific legal restrictions similar to Sanctuaries.

Statement 2 and Statement 3 are correct

, while Statements 1 and 4 are incorrect. The primary objective is to protect the landscape and biodiversity while involving the local community in management, but once notified, certain "traditional" rights—specifically shifting cultivation and hunting—are legally restricted to preserve the ecological integrity of the area.

Statement 1: The Chief Wildlife Warden of the State becomes the governing authority of such forest.

• Incorrect.
• Reason: According to Section 36D of the Wildlife (Protection) Act, the management of a Community Reserve is vested in a Community Reserve Management Committee. While the Chief Wildlife Warden appoints the committee and oversees the management plan, they are not the "governing authority." The committee is responsible for conserving and managing the reserve. This is a common distractor designed to confuse Community Reserves with National Parks or Sanctuaries where the state exert more direct control.

Statement 2: Hunting is not allowed in such areas.

• Correct.
• Reason: Once an area is declared a Community Reserve under Section 36C, the provisions of the Wildlife (Protection) Act apply. Hunting is strictly prohibited in all protected areas (National Parks, Sanctuaries, Conservation Reserves, and Community Reserves) as per the overarching mandate of the Act to protect wildlife from exploitation.

Statement 3: People of such areas are allowed to collect non-timber forest produce.

• Correct.
• Reason: The law allows the local community to continue sustainable practices that do not harm the habitat. Collection of Non-Timber Forest Produce (NTFP) like honey, fallen leaves, or medicinal herbs is permitted for the subsistence of the local communities, subject to the management plan approved by the Committee.

Statement 4: People of such areas are allowed traditional agricultural practices.

• Incorrect.
• Reason: The Act specifically states that after a notification is issued, "no change in the land use pattern shall be made within the Community Reserve, except in accordance with a resolution passed by the Management Committee and approval by the State Government." Crucially, traditional practices like shifting cultivation (Jhum) are generally restricted or disallowed because they involve clearing forest land, which contradicts the "reserve" status meant for conservation.

Key Takeaway:

The core concept is the degree of community autonomy versus state regulation in Protected Areas. Community Reserves allow for local participation through a Management Committee and permit non-extractive uses like NTFP collection, but they strictly prohibit hunting and land-use changes (like shifting agriculture) to ensure biodiversity conservation.

Option B follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

When Janani Suraksha Yojana was reported, it made Janani Suraksha Yojana a live current-affairs theme for Prelims.

Analysing the Question

Option B (Only two) is the correct answer because, among the four statements provided, only Statement 2 and Statement 3 are factually accurate regarding the Janani Suraksha Yojana (JSY).

Launched in April 2005 under the National Health Mission (NHM), JSY is a 100% Centrally Sponsored Scheme. Its primary design is to integrate cash assistance with delivery and post-delivery care. The scheme focuses on "Low Performing States" (LPS) and "High Performing States" (HPS) to incentivize institutional births, thereby bridging the gap in maternal healthcare services between the rich and the poor.

Statement 1

It is a safe motherhood intervention of the State Health Departments. * Incorrect. * Reason: While the scheme is implemented through State health machineries, it is a Central Government initiative (Centrally Sponsored Scheme) under the Ministry of Health and Family Welfare. UPSC often uses "State Health Departments" as a distractor to test the student’s knowledge of the scheme's origin—whether it is Central or State-specific.

Statement 2

Its objective is to reduce maternal and neonatal mortality among poor pregnant women. * Correct. * Reason: The fundamental objective of JSY is to reduce Maternal Mortality Ratio (MMR) and Neonatal Mortality Rate (NMR). It targets Below Poverty Line (BPL) households to ensure that financial constraints do not lead to unsafe home deliveries.

Statement 3

It aims to promote institutional delivery among poor pregnant women. * Correct. * Reason: JSY provides direct cash transfers to pregnant women who opt for delivery in government or accredited private health facilities. By providing this financial incentive, the scheme directly promotes institutional delivery over high-risk home births.

Statement 4

Its objective includes providing public health facilities to sick infants up to one year of age. * Incorrect. * Reason: This is a common point of confusion. The provision of free treatment for sick infants up to one year is a feature of the Janani Shishu Suraksha Karyakram (JSSK), launched in 2011, not JSY (2005). JSY is primarily focused on the act of delivery and immediate post-partum care/incentives. UPSC includes this to test if the candidate can distinguish between two closely related schemes under the NHM umbrella.

Summary of Selection:

• Statement 1: Incorrect (Central, not State scheme)
• Statement 2: Correct
• Statement 3: Correct
• Statement 4: Incorrect (Refers to JSSK, not JSY)
• Total Correct: 2 (Matches Option B)

Correct Answer: B

The Janani Suraksha Yojana (JSY) is a Centrally Sponsored cash-incentive scheme focused specifically on reducing MMR/NMR by promoting institutional deliveries. It should not be confused with JSSK, which covers the expenses of sick infants and provides entitlements like free drugs and diagnostics.

When Anaemia Mukt Bharat was reported, it made Anaemia Mukt Bharat a live current-affairs theme for Prelims.

Analysing the Question

Option C (Only three statements are correct)

. The Anaemia Mukt Bharat (AMB) strategy, launched in 2018 by the Ministry of Health and Family Welfare, follows a 6x6x6 strategy (6 target groups, 6 interventions, and 6 institutional mechanisms).

The strategy focuses on Iron and Folic Acid (IFA) supplementation, not calcium. Statements 2, 3, and 4 are explicit components of the six interventions designed to reduce the prevalence of anaemia across the life cycle. Statement 1 is incorrect because it cites the wrong mineral supplement.

Statement 1

It provides prophylactic calcium supplementation for pre-school children, adolescents and pregnant women. * Incorrect. * The Error: The core of the AMB strategy is Prophylactic Iron and Folic Acid (IFA) supplementation, not calcium. While calcium may be provided during pregnancy under other maternal health programs (like PMNCH), it is not a defining intervention of the Anaemia Mukt Bharat framework. * UPSC Distractor: This is a "substitution trap." UPSC often replaces the primary nutrient (Iron/Folic Acid) with another common supplement (Calcium) to test if the candidate knows the specific medical focus of the scheme.

Statement 2

It runs a campaign for delayed cord clamping at the time of child-birth. * Correct. * Fact: One of the six interventions is "Institutionalizing Delayed Cord Clamping (DCC)" for at least 3 minutes after birth. This increases the infant's iron stores by up to 30%, preventing anaemia in the first vital months of life.

Statement 3

It provides for periodic deworming to children and adolescents. * Correct. * Fact: Bi-annual mass deworming (using Albendazole) is a pillar of the strategy. It targets children (1-19 years) to prevent blood loss caused by hookworm and other helminthic infestations, which are major contributors to anaemia in India.

Statement 4

It addresses non-nutritional causes of anaemia in endemic pockets with special focus on malaria, hemoglobinopathies and fluorosis. * Correct. * Fact: The strategy acknowledges that anaemia isn't just about diet. In specific "endemic pockets," it focuses on screening and treating Malaria, Hemoglobinopathies (like Sickle Cell Anemia and Thalassemia), and Fluorosis, as these conditions directly impact red blood cell health.

Correct Answer: C

The Anaemia Mukt Bharat (AMB) strategy relies on the 6x6x6 framework, emphasizing Iron-Folic Acid (IFA) supplementation, deworming, and delayed cord clamping, while addressing geographical-specific non-nutritional causes like malaria and fluorosis.

Why This Question Was Asked

In 14 Dec 2022, TSF Group unveils carbon fibre parts manufacturing plant put Carbon fibre manufacturing in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option A (1 only) is the correct answer.

Carbon fiber is an advanced material composed of thin, strong crystalline filaments of carbon. Statement 1 is factually accurate because Carbon Fiber Reinforced Polymers (CFRPs) possess a high strength-to-weight ratio and excellent rigidity.

• In aircraft manufacturing, carbon fibers are essential for reducing fuel consumption by lowering the overall weight of the aircraft (e.g., the Boeing 787 Dreamliner uses approximately 50% carbon fiber).
• In the automobile industry, they are used in high-performance vehicles, Formula 1 cars, and increasingly in electric vehicles (EVs) to increase range by reducing chassis weight.

Statement 2 is factually incorrect because carbon fibers can be recycled, though the process is more complex than recycling metals. Methods such as pyrolysis (thermal decomposition) and solvolysis (chemical recycling) are used to recover carbon fibers from old composite materials.

Option A: 1 only

• Correct.
• As discussed above, Statement 1 is a well-established application of carbon fiber technology. Its resistance to corrosion and thermal expansion makes it superior to traditional aluminum or steel for critical aerospace and automotive components. Since Statement 2 is false, this is the only logical choice.

Option B: 2 only

• Incorrect.
• Factual Error: The statement claims carbon fibers cannot be recycled. In reality, while recycling carbon fiber is technically challenging due to the "permanent" nature of the thermoset resins used to bind them, it is entirely possible.
• UPSC Distractor Logic: UPSC often uses absolute words like "cannot," "never," or "only" to test a candidate's depth of knowledge. Students often assume that because it is a "plastic-like" composite, it is non-recyclable like typical single-use plastics.

Option C: Both 1 and 2

• Incorrect.
• While Statement 1 is true, Statement 2 is false. Advanced recycling facilities (especially in Europe and North America) are already reclaiming carbon fiber from decommissioned aircraft wings and wind turbine blades to create non-structural components like car interior trims or laptop casings.

Option D: Neither 1 nor 2

• Incorrect.
• This option is wrong because Statement 1 is a verified, foundational fact of modern material science and industrial engineering.

Correct Answer: A

Carbon fibers are vital for lightweighting in the aerospace and automotive sectors; while they are highly durable and chemically stable, they can be recycled through thermal or chemical processes to recover the fiber for secondary use.

Why This Question Was Asked

In 2 Dec 2022, Study flags poor compliance by West Bengal power plants in pollution control put Mercury emission norms in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option B (Only two)

. This question tests the candidate’s knowledge of both the sources of heavy metal pollution and the biological impact of such toxins. While statements 1 and 2 are well-documented facts in environmental science and international treaties (like the Minamata Convention), statement 3 is technically incorrect in a regulatory and toxicological context, despite mercury's high toxicity.

Option A: Only one

• Incorrect.
  • This option is incorrect because there is more than one factually accurate statement. Candidates often pick this if they are only aware of industrial sources (like power plants) but unaware of the significant role of artisanal mining in mercury pollution.

Option B: Only two

• Correct.
  • Statement 1 is correct: Artisanal and Small-scale Gold Mining (ASGM) is the largest anthropogenic source of mercury emissions globally. Mercury is used to capture gold particles by forming an amalgam; the mercury is then burned off, releasing vapor into the atmosphere.
  • Statement 2 is correct: Coal naturally contains trace amounts of mercury. When coal is burned in thermal power plants, this mercury is released into the air. It is considered one of the major industrial sources of mercury pollution.
  • Statement 3 is incorrect: While mercury is highly toxic and "no level is considered completely risk-free" in a general sense, international health organizations (like the WHO and FAO) do establish "Provisional Tolerable Weekly Intake" (PTWI) levels or "Reference Doses." These are defined levels of exposure below which no adverse health effects are expected. Therefore, saying there is "no known safe level" is a factual error in a regulatory/scientific framework, unlike lead, for which the WHO explicitly states there is no known safe blood concentration.

Option C: All three

• Incorrect.
  • This is a common distractor. Students often assume that for highly toxic substances (like mercury, arsenic, or radiation), there is "no safe level." While mercury is a potent neurotoxin, regulatory bodies have quantified "safe" exposure thresholds for consumption (especially regarding Methylmercury in fish). UPSC uses extreme phrasing ("no known safe level") to differentiate between generally "dangerous" substances and those where science has literally failed to find a threshold of safety.

Option D: None

• Incorrect.
  • This is incorrect as Statements 1 and 2 are globally recognized facts supported by the Minamata Convention on Mercury (2013), an international treaty designed to protect human health and the environment from anthropogenic emissions of mercury.

Key Takeaway

Mercury pollution primarily stems from gold mining (ASGM) and coal combustion. While highly toxic, it differs from substances like lead because health authorities still maintain specific tolerable intake levels (safe thresholds) for mercury exposure.

Correct Answer: B

Therefore, saying there is "no known safe level" is a factual error in a regulatory/scientific framework, unlike lead, for which the WHO explicitly states there is no known safe blood concentration.

Why This Question Was Asked

In 5 Jan 2023, Explained | India’s plan to develop green hydrogen put Green hydrogen mission in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option C (All three)

is the correct answer because Green Hydrogen, produced through the electrolysis of water using renewable energy, is a versatile energy carrier. Its chemical properties allow it to be integrated into existing infrastructure, converted into electricity through chemical reactions, or combusted directly for thermal energy.

According to the National Green Hydrogen Mission (launched in 2023) and studies by organizations like the International Renewable Energy Agency (IRENA), green hydrogen is a critical pillar for decarbonizing sectors that are hard to electrify. It can substitute fossil fuels in high-temperature industrial processes, transportation, and power generation.

Statement 1

It can be used directly as a fuel for internal combustion. * Correct. Hydrogen can be used in Hydrogen Internal Combustion Engine Vehicles (HICEV). While fuel cells are more efficient, modified ICE engines (similar to those used for CNG or petrol) can burn hydrogen directly to produce mechanical power. This is particularly relevant for heavy-duty trucking and off-road vehicles.

Statement 2

It can be blended with natural gas and used as fuel for heat or power generation. * Correct. Hydrogen blending (H-CNG) is a proven transition strategy. In India, companies like NTPC and GAIL have initiated pilot projects for blending hydrogen into the National Gas Grid. Hydrogen-blended natural gas can be used in household stoves for heating or in gas turbines for power generation without requiring major modifications to the distribution infrastructure (up to certain percentage limits).

Statement 3

It can be used in the hydrogen fuel cell to run vehicles. * Correct. This is perhaps the most well-known application. In a Fuel Cell Electric Vehicle (FCEV), hydrogen reacts with oxygen from the air in a fuel cell stack to produce electricity, which then powers an electric motor. The only byproduct is water vapor ($H_2O$), making it a zero-emission technology at the point of use.

Evaluation of Options

Option A: Only one

• Incorrect. Since all three applications are scientifically established and practically implemented in pilot projects worldwide, selecting only one would ignore the multi-sectoral utility of hydrogen.

Option B: Only two

• Incorrect. UPSC often uses this as a distractor for candidates who might recognize fuel cells (Statement 3) and blending (Statement 2) but remain skeptical about direct combustion (Statement 1) due to the thermal efficiency dominance of fuel cells.

Option C: All three

• Correct. As detailed above, green hydrogen serves as a direct fuel, a blending agent, and a feedstock for electricity generation.

Option D: None of the above

• Incorrect. This is factually false as green hydrogen is a central component of global and Indian energy transition policies.

Correct Answer: C

Green Hydrogen is a "versatile" energy molecule. It is not limited to electricity generation via fuel cells but can also function as a combustible fuel (either alone or blended with natural gas) to decarbonize transport, heating, and industrial power.

Why This Question Was Asked

When Ukraine war borders was reported, it made Ukraine war borders a live current-affairs theme for Prelims.

Analysing the Question

Option A (Only two)

.

Ukraine is located in Eastern Europe and is the second-largest country on the continent. Geopolitically, it shares land borders with seven countries:

1. Russia (East and Northeast)
2. Belarus (North)
3. Poland (West)
4. Slovakia (West)
5. Hungary (Southwest)
6. Romania (Southwest and South)
7. Moldova (South)

From the list provided in the question, only Hungary (3) and Romania (6) share a direct land border with Ukraine. The other countries mentioned are either separated by other nations or located further north in the Baltic region.

Option A: Only two

• Correct.
  • The two countries from the list that border Ukraine are Hungary and Romania. Hungary shares a 137 km border with Ukraine’s Zakarpattia Oblast. Romania shares a divided border with Ukraine (separated by Moldova) totaling approximately 613 km, including sections in the north and the south along the Danube delta.

Option B: Only three

• Incorrect.
  • This option is a distractor for students who might mistake Bulgaria or Moldova (not in the list) as bordering Ukraine. While Bulgaria is a Black Sea nation like Ukraine, it is separated from Ukraine by Romania.

Option C: Only four

• Incorrect.
  • This might be chosen if a candidate incorrectly assumes that the Baltic nations (Latvia and Lithuania) or the Czech Republic extend far enough east to touch Ukraine. In reality, Poland and Belarus act as a buffer between these nations and Ukraine.

Option D: Only five

• Incorrect.
  • This option assumes nearly all listed countries share a border. This is a common trap for candidates who have a general sense of the "Eastern Bloc" or "Central European" location of these countries but lack precise map visualization.

Detailed Check of Incorrect Nations from the List:

• Bulgaria: Separated from Ukraine by Romania.
• Czech Republic: Separated from Ukraine by Poland and Slovakia.
• Latvia: Located further north; borders Russia and Belarus, but not Ukraine.
• Lithuania: Borders Poland, Latvia, and Belarus, but does not reach Ukraine.

Key Takeaway:

In current affairs-heavy topics like the Russia-Ukraine conflict, UPSC tests precise map-based knowledge of "Frontline States" and neighboring regions. To solve such questions, one must remember that Ukraine is bordered by Poland, Slovakia, Hungary, Romania, Moldova, Belarus, and Russia.

Correct Answer: A

Option A follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

In 9 Jul 2022, Artificial diet, feeding device for mosquitoes put Wolbachia dengue VCRC in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option A is correct.

The Wolbachia method is a biological control strategy used to reduce the transmission of viral diseases such as Dengue, Zika, Chikungunya, and Yellow Fever, which are primarily spread by the Aedes aegypti mosquito.

Wolbachia is a common genus of bacteria that exists naturally in about 60% of all insect species, but it does not naturally occur in Aedes aegypti. Scientists have found that when Aedes aegypti mosquitoes are intentionally infected with Wolbachia, the bacteria compete with viruses like Dengue within the mosquito's body. This makes it much harder for the virus to replicate, thereby significantly reducing the mosquito's ability to transmit the disease to humans.

This method gained global attention through projects like the World Mosquito Program (WMP). Unlike genetic modification, this is a "biocontrol" approach where Wolbachia-carrying mosquitoes are released into the wild to breed with the local population, eventually passing the bacteria down through generations and creating a disease-resistant mosquito population.

Option A: Controlling the viral diseases spread by mosquitoes

• Correct.
  • As explained above, Wolbachia acts as a biological shield. It is a sustainable, non-chemical, and non-GMO method to curb the spread of arboviruses. Pilot projects in countries like Indonesia and Brazil have shown a massive reduction in Dengue incidence after the introduction of Wolbachia mosquitoes.

Option B: Converting crop residues into packing material

• Incorrect.
  • This process usually involves Mycelium-based packaging (using fungi) or mechanical and chemical processing of agricultural waste into pulp. While "biological agents" are used in this field, Wolbachia is a bacterium specifically hosted by insects and has no role in breaking down cellulose or lignin in crop residues. This is a distractor targeting students familiar with "Circular Economy" or "Waste-to-Wealth" initiatives.

Option C: Producing biodegradable plastics

• Incorrect.
  • Biodegradable plastics (like PHA - Polyhydroxyalkanoates) are typically produced through the fermentation of sugar or lipids by specific bacteria like Bacillus or Pseudomonas. Wolbachia is an endosymbiont (lives inside host cells) and cannot be cultured outside an insect host for industrial production. This option exploits the general knowledge that "bacteria are used to make bioplastics."

Option D: Producing biochar from thermochemical conversion of biomass

• Incorrect.
  • The production of biochar involves Pyrolysis (heating biomass in a low-oxygen environment). This is a purely thermochemical process, not a biological one involving bacteria. UPSC includes this to confuse students with other "Bio-" prefixed terms like Bio-CNG, Bio-ethanol, or Biochar, which are frequent topics in environmental technology.

Key Takeaway:

The Wolbachia method is a biocontrol technique that uses naturally occurring bacteria to inhibit the replication of viruses within mosquitoes, effectively neutralizing them as vectors for diseases like Dengue and Zika.

Correct Answer: A

Option A follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

In 29 Nov 2022, NITI Aayog proposes decarbonising of industrial emissions put Carbon capture basalt CCUS in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option C

because all three activities listed are recognized methods within the scientific field of Carbon Dioxide Removal (CDR) and Carbon Capture and Storage (CCS). These techniques aim to mitigate climate change by either removing $CO_2$ from the atmosphere or preventing it from entering it.

1. Enhanced Rock Weathering (ERW): Spreading basalt on farmlands accelerates a natural chemical process where silicate rocks react with $CO_2$ to form stable carbonates.
2. Ocean Alkalinity Enhancement (OAE): Adding lime ($Ca(OH)_2$) to oceans increases their capacity to absorb and store $CO_2$ while simultaneously countering ocean acidification.
3. Geological Sequestration: Pumping carbonated water (dissolved $CO_2$) into subterranean reservoirs (like basaltic formations or abandoned mines) leads to mineral carbonation, effectively "turning gas into stone."

Option A: Only one

• Incorrect.
  • This option is incorrect because it underestimates the breadth of geoengineering strategies currently discussed in IPCC reports and international climate forums. Candidates often pick this if they are only familiar with traditional biological sequestration (like afforestation) and view industrial or chemical methods as "science fiction."

Option B: Only two

• Incorrect.
  • This is a common distractor for candidates who may recognize geological storage (Statement 3) and perhaps one mineral-based method but are skeptical of the other. For instance, one might doubt the feasibility of "ocean liming" due to scale, yet it remains a widely "discussed and considered" theoretical strategy for carbon sequestration.

Option C: All three

• Correct.
  • Statement 1: Basalt is rich in calcium and magnesium. When ground up, its surface area increases, allowing it to react faster with rain and atmospheric $CO_2$ to form bicarbonate ions. This is a legitimate carbon sequestration strategy discussed in the context of regenerative agriculture.
  • Statement 2: Increasing ocean alkalinity is a primary geoengineering proposal. By adding alkaline substances like lime or olivine, the ocean's chemical equilibrium shifts, allowing it to absorb more $CO_2$ from the air.
  • Statement 3: This refers to In-situ Mineral Carbonation. A famous example is the CarbFix project in Iceland, which dissolves $CO_2$ in water (carbonated water) and pumps it into underground basaltic rocks where it mineralizes into solid calcite within years.

Option D: None

• Incorrect.
  • This option is factually wrong. All three methods are active areas of research and are included in various climate change mitigation dialogues globally (e.g., London Convention on Marine Pollution, IPCC Assessment Reports).

Key Takeaway

The UPSC is testing knowledge of Carbon Capture and Sequestration (CCS) beyond simple tree planting, focusing on Enhanced Weathering, Ocean Geoengineering, and Mineral Carbonation as technological solutions for climate change.

Correct Answer: C

Option C follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

In 9 Dec 2022, Oldest DNA reveals life in Greenland 2 million years ago put Environmental DNA metagenomics in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option A

is the correct answer because Aerial Metagenomics refers to the technique of monitoring terrestrial biodiversity by sampling environmental DNA (eDNA) directly from the air.

Metagenomics is the study of genetic material recovered directly from environmental samples (like soil, water, or air) rather than from individual organisms cultivated in a lab. In 2022-2023, two landmark studies (by researchers at York University and the University of Copenhagen) demonstrated that vacuum devices could capture enough eDNA from the air to identify a wide range of animals (mammals, birds, and insects) living in the vicinity. As animals move, breathe, or shed skin/fur, they release DNA into the air. Aerial metagenomics allows scientists to survey entire ecosystems "at one go" without needing to see or capture the animals themselves.

Option A: Collecting DNA samples from air in a habitat at one go

• Correct.
  • This captures the essence of both "Aerial" (from the air) and "Metagenomics" (the study of a collection of genomes from a mixed environmental sample). It is a non-invasive method for biodiversity monitoring that has recently gained scientific prominence as a high-tech alternative to camera traps.

Option B: Understanding the genetic makeup of avian species of a habitat

• Incorrect.
  • While "aerial" might suggest birds (avian species), metagenomics is not limited to birds. It captures DNA from mammals, amphibians, and insects that live on the ground but shed DNA into the air.
  • Distractor Logic: UPSC uses this to trick candidates who associate "aerial" strictly with flight or birds, ignoring the technological aspect of DNA sampling from the atmosphere.

Option C: Using air-borne devices to collect samples from moving animals

• Incorrect.
  • This implies a physical interaction or proximity-based sampling from specific moving animals (like a drone taking a swab or hair sample).
  • Scientific Correction: Aerial metagenomics does not target a specific "moving animal"; it targets the ambient air which contains a "soup" of DNA from multiple species simultaneously.
  • Distractor Logic: This appeals to students who know technology (drones) is involved but misunderstand the molecular method (eDNA).

Option D: Sending drones to inaccessible areas to collect plant and animal samples from land surfaces and water bodies

• Incorrect.
  • This describes traditional biological sampling or "Environmental DNA" from water/soil, but it emphasizes "land surfaces and water bodies" rather than the air itself.
  • Scientific Correction: While drones are tools, metagenomics specifically refers to the genetic analysis process. Collecting bulk samples from land/water is standard field biology; "Aerial" metagenomics specifically uses the atmosphere as the medium for sampling.
  • Distractor Logic: This is a "common sense" distractor that describes general remote sensing or drone-based ecology, which is often confused with molecular biology.

Correct Answer: A

Aerial metagenomics is an emerging non-invasive technology used to monitor biodiversity by filtering environmental DNA (eDNA) from the air, allowing for the identification of multiple species in a habitat without direct physical contact.

Why This Question Was Asked

In 31 Oct 2022, RBI Digital Rupee pilot for wholesale segment from November 1 put Digital rupee CBDC pilot in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option C (Both 1 and 2) is correct because Central Bank Digital Currencies (CBDCs) are designed to function as a digital form of fiat currency, leveraging distributed ledger technology (DLT) or centralized databases to offer functionalities that traditional electronic money lacks.

• Logic for Statement 1: Currently, international trade and cross-border payments heavily rely on the SWIFT (Society for Worldwide Interbank Financial Telecommunication) messaging system and the US Dollar as a reserve currency. CBDCs allow for "interoperability" between different nations' central bank ledgers. This enables direct peer-to-peer (P2P) or bank-to-bank transfers across borders without needing a centralized intermediary like SWIFT or a clearinghouse based in a third-party country (like the US).
• Logic for Statement 2: CBDCs are "programmable" money. Unlike physical cash or standard bank deposits, a CBDC can be embedded with smart contracts. This allows the issuing authority (like the RBI) to set specific parameters, such as "expiry dates" or "purpose-bound" spending (e.g., a direct benefit transfer for fertilizers that can only be spent at designated outlets within a specific timeframe).

Option A: 1 only

• Incorrect.
  • While Statement 1 is factually correct, this option is incomplete. It ignores the programmable nature of digital currencies. UPSC often uses "1 only" as a distractor for students who understand the geopolitical implications of CBDCs but are unaware of the technical "smart contract" capabilities of the currency itself.

Option B: 2 only

• Incorrect.
  • While Statement 2 is factually correct, this option is incomplete. It fails to acknowledge that CBDCs can bypass traditional financial plumbing (SWIFT). Students might choose this if they believe that global trade must always involve the US Dollar, failing to recognize that CBDCs create a new "railway" for value transfer.

Option C: Both 1 and 2

• Correct.
  • Both statements accurately reflect the core advantages of CBDCs. Statement 1 addresses efficiency and sovereignty in international settlements (reducing dependence on Western-centric systems), while Statement 2 addresses precision in monetary policy and social engineering (ensuring funds are used for their intended purpose via programming).

Option D: Neither 1 nor 2

• Incorrect.
  • This option is factually wrong on both counts. Modern deployments of CBDCs (like China’s e-CNY or India’s e-Rupee) have already demonstrated both the ability to settle trades outside traditional systems and the ability to program use-cases.

Key Takeaway:

CBDCs represent a shift from "dumb" money to "programmable" money; they enable direct cross-border settlement (bypassing SWIFT) and purpose-linked spending (using smart contracts), fundamentally changing how central banks manage liquidity and governance.

Correct Answer: C

Option C follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

In 25 Jan 2023, Adani shares fall as short-seller Hindenburg Research flags its ‘substantial debt’ put Adani beta Hindenburg in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option D is correct because in financial modeling and investment analysis, Beta ($\beta$) is a specific measure of systematic risk, or the sensitivity of an individual security or portfolio in comparison to the entire market.

Calculated using regression analysis, Beta represents the tendency of a stock's returns to respond to swings in the market. A benchmark index (like the Nifty 50 or S&P 500) always has a Beta of 1.0.

• If a stock has a Beta > 1, it is more volatile than the market (e.g., if the market rises 10%, the stock might rise 15%).
• If a stock has a Beta < 1, it is less volatile (defensive stocks).
• This concept is a core component of the Capital Asset Pricing Model (CAPM), used to calculate the expected return of an asset based on its risk.

Option A

"the process of simultaneous buying and selling of an asset from different platforms" * Incorrect. * This is the definition of Arbitrage. Arbitrageurs exploit price discrepancies of the same asset in different markets (e.g., buying a stock on the BSE and selling it on the NSE for a slim profit). This is a common distractor because it is a fundamental trading term, but it describes a strategy rather than a measurement of risk.

Option B

"an investment strategy of a portfolio manager to balance risk versus reward" * Incorrect. * This broadly describes Portfolio Management or Asset Allocation. While Beta is a tool used in this process, the definition provided is too general. UPSC includes this to test if the candidate can distinguish between a broad objective (balancing risk/reward) and a specific mathematical metric (Beta).

Option C

"a type of systemic risk that arises where perfect hedging is not possible" * Incorrect. * This refers to Basis Risk. While Beta measures systematic risk (market-wide risk), Option C describes a failure in a hedging strategy. "Systemic" risk refers to the collapse of an entire financial system, whereas "Beta" specifically measures a stock's correlation to "systematic" (market) risk. This is a high-level distractor that confuses similar-sounding financial terminology.

Option D

"a numeric value that measures the fluctuations of a stock to changes in the overall stock market" * Correct. * As explained, Beta is a statistical measure of relative volatility. It tells an investor how much "market risk" they are taking on by holding a specific security compared to a diversified market index.

Correct Answer: D

Beta ($\beta$) is a measure of a security’s volatility relative to the market; it quantifies systematic risk, helping investors understand how much a stock will likely move in response to broader market fluctuations.

In 17 Feb 2023, Govt. close to achieve target of 10 crore women members in Self Help Groups, says Minister put SHG DAY-NRLM budget in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option B (Only two)

. This is because statements 2 and 3 are factually accurate, while statement 1 contains a historical inaccuracy regarding the origin of the SHG-Bank Linkage Programme in India.

In the Indian context, the Self-Help Group (SHG) movement gained formal institutional momentum through the NABARD (National Bank for Agriculture and Rural Development) pilot project in 1992, not the State Bank of India. The core philosophy of SHGs relies on social collateral and joint liability, making all members responsible for individual defaults. Furthermore, the Indian banking architecture, including RRBs and SCBs, is deeply integrated into the SHG-Bank Linkage Programme (SHG-BLP) to promote financial inclusion.

Option A: Only one

• Incorrect.
  • This option is incorrect because there are two valid statements (2 and 3). Candidates often pick this if they are unaware of the "joint liability" clause or believe only NABARD (and not commercial banks) supports SHGs.

Option B: Only two

• Correct.
  • Statement 2 is Correct: SHGs function on the principle of collective responsibility. While a loan may be taken by an individual member for personal or micro-enterprise use, the entire group stands as a guarantor. This peer pressure ensures high repayment rates.
  • Statement 3 is Correct: The SHG-Bank Linkage Programme is supported by a wide array of financial institutions. Regional Rural Banks (RRBs), Scheduled Commercial Banks (SCBs), and Cooperative Banks all provide credit and savings facilities to SHGs under RBI and NABARD guidelines.

Option C: All three

• Incorrect.
  • This option is incorrect because Statement 1 is false.
  • Factual Error: The SHG-Bank Linkage Programme was initiated by NABARD in 1992, following the recommendations of the S.K. Kalia Committee. While SBI is a major participant today, it was not the originator.
  • UPSC Distractor Strategy: UPSC often swaps the names of nodal agencies (e.g., swapping NABARD with SBI or RBI) to test a candidate's precision regarding the institutional history of financial schemes.

Option D: None

• Incorrect.
  • This option is incorrect as statements 2 and 3 are well-established facts in the Indian microfinance and rural banking sector.

Key Takeaway

The SHG-Bank Linkage Programme, pioneered by NABARD (1992), serves as the world's largest microfinance project, operating on the principle of joint liability and supported by the entire spectrum of Scheduled Commercial Banks and RRBs.

Correct Answer: B

Option B follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

In 10 Nov 2022, Level of groundwater extraction lowest in 18 years, finds study put UN groundwater report India in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Statement-I is correct.

According to the United Nations World Water Development Report 2022, India is the largest extractor of groundwater in the world. It extracts approximately 251 cubic kilometers (km³) of groundwater annually, which accounts for more than 25% (one-fourth) of the total global groundwater withdrawal. This staggering volume is greater than the groundwater extraction of China and the USA combined.

Statement-II is incorrect.

While it is a factual reality that India supports roughly 18% of the world's population, the primary reason for the high extraction of groundwater is not "drinking water and sanitation needs." In reality, about 89% to 90% of India's groundwater withdrawal is used for irrigation in the agricultural sector. Only a small fraction (roughly 5-9%) is used for domestic purposes, including drinking water and sanitation, and the remaining is used for industrial needs. Therefore, the statement identifies the wrong "primary driver" for the extraction volume.

Option A: Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I.

• Incorrect.
  • While Statement-I is a verified fact from the UN report, Statement-II is factually flawed because it misrepresents the purpose of the extraction. UPSC uses this as a distractor by linking two "plausible-sounding" facts (population size and water needs), but the causal link is scientifically and statistically false since agriculture, not domestic use, is the main consumer.

Option B: Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I.

• Incorrect.
  • This option is incorrect because it presumes Statement-II is factually right. As established, Statement-II is factually incorrect regarding the reason for the volume of extraction.

Option C: Statement-I is correct but Statement-II is incorrect.

• Correct.
  • Statement-I accurately reflects the data from the 2022 UN report regarding India’s global share of groundwater withdrawal. Statement-II is incorrect because the vast majority of extracted groundwater in India feeds the Green Revolution's irrigation requirements rather than just drinking water and sanitation.

Option D: Statement-I is incorrect but Statement-II is correct.

• Incorrect.
  • This option is wrong because Statement-I is a well-documented figure used by various international and national agencies (including India's Central Ground Water Board) to highlight the groundwater crisis.

Key Takeaway:

India is the world's largest consumer of groundwater, extracting over 25% of the global total; however, nearly 90% of this extraction is driven by agricultural irrigation, not domestic consumption or sanitation.

Correct Answer: C

Therefore, the statement identifies the wrong "primary driver" for the extraction volume.

Why This Question Was Asked

In 5 Jan 2023, Madras HC orders expeditious trial in case booked against 33 suspected Naxalites under POTA put POTA Madras HC in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option B (Only two)

. Statements 1 and 2 are factually and constitutionally correct, while Statement 3 is incorrect regarding the specific provisions of the repealed Prevention of Terrorism Act (POTA), 2002.

Statement Analysis:

Statement 1

"According to the Constitution of India, the Central Government has a duty to protect States from internal disturbances." * Status: Correct. * Explanation: This is directly enshrined in Article 355 of the Constitution of India. It states: "It shall be the duty of the Union to protect every State against external aggression and internal disturbance and to ensure that the government of every State is carried on in accordance with the provisions of this Constitution." This article provides the constitutional basis for the Union to intervene in state matters during times of crisis.

Statement 2

"The Constitution of India exempts the States from providing legal counsel to a person being held for preventive detention." * Status: Correct. * Explanation: Article 22 provides safeguards against arrest and detention. However, Article 22(3) explicitly states that the protections of Clauses (1) and (2)—which include the right to consult and be defended by a legal practitioner of one's choice—do not apply to any person who is arrested or detained under any law providing for preventive detention. While the detaining authority must provide the grounds for detention and an opportunity to make a representation, the constitutional right to legal counsel is explicitly excluded for such detainees.

Statement 3

"According to the Prevention of Terrorism Act 2002, the confession of the accused before the police cannot be used as evidence." * Status: Incorrect. * Explanation: Under ordinary law (Section 25 of the Indian Evidence Act), a confession made to a police officer is not admissible as evidence. However, POTA (2002) was a special law that contained a contrary provision. Section 32 of POTA specifically stated that a confession made by a person before a police officer (not lower in rank than a Superintendent of Police) shall be admissible in the trial of such person. This was one of the most controversial aspects of the Act before it was repealed in 2004.

Option A: Only one

• ❌ INCORRECT. This option would be correct if only one statement were true. Since both Statement 1 (Article 355) and Statement 2 (Article 22 exceptions) are correct, this option is false.

Option B: Only two

• ✅ CORRECT. As established, Statements 1 and 2 are constitutionally valid. Statement 3 is factually incorrect because POTA allowed police confessions as admissible evidence, breaking from standard evidentiary rules.

Option C: All three

• ❌ INCORRECT. This assumes Statement 3 is correct. UPSC includes Statement 3 as a distractor because students often generalize that "police confessions are never admissible in India." While true for the Evidence Act, the "special power" of POTA was exactly the opposite.

Option D: None

• ❌ INCORRECT. This would imply all statements are false. Since the first two are direct constitutional provisions, this option is logically ruled out.

Correct Answer: B

This question tests the student's ability to distinguish between General Provisions (Indian Evidence Act) and Special Laws (POTA), alongside an in-depth understanding of Emergency-related duties (Article 355) and Fundamental Right exceptions (Article 22).

Why This Question Was Asked

In 19 Apr 2022, Explained | How grave is the drought emergency in Somalia? put Somalia drought famine in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option D (Somalia)

is the correct answer. Somalia has been entrenched in a state of civil war since the collapse of the Siad Barre regime in 1991. The conflict involves various factions, including the federal government, regional states, and the Al-Qaeda-linked insurgent group Al-Shabaab.

In the "recent past" (specifically 2022–2023), Somalia faced its worst drought in four decades, following five consecutive failed rainy seasons. This climate catastrophe, compounded by global supply chain disruptions (the Russia-Ukraine war impacted grain imports) and the ongoing internal insurgency, pushed the country to the brink of a catastrophic famine. According to reports by the United Nations (UN) and the Integrated Food Security Phase Classification (IPC), millions of Somalis faced acute food insecurity, with over 200,000 people reaching "Catastrophic" (Phase 5) levels of hunger. The situation mirrored the 2011 famine in Somalia, which claimed over a quarter-million lives.

Option A: Angola

• Incorrect.
  • While Angola suffered a brutal civil war for 27 years after its independence (1975–2002), the country has remained relatively stable since the peace agreement in 2002. Although it faces economic challenges and localized food insecurity due to periodic droughts in the south, it was not in the news for "severe famine" or "decades of strife" in the contemporary context (2022–2023) compared to Somalia. This is a common distractor because it is a classic example of historical civil strife in Africa.

Option B: Costa Rica

• Incorrect.
  • Costa Rica is one of the most stable and prosperous countries in Latin America. It is famously known for having abolished its military in 1948 and has not suffered from civil strife or famine in the modern era. This option acts as a "clear outlier" for students to eliminate.

Option C: Ecuador

• Incorrect.
  • Ecuador has experienced periods of political instability and recent spikes in drug-related violence/cartel activity; however, it has not suffered "decades of civil strife" in the manner of a civil war, nor has it faced a "severe famine." Its issues are largely related to economic policy and organized crime rather than endemic hunger.

Option D: Somalia

• Correct.
  • Somalia fits all three criteria mentioned in the question:
    1. Decades of civil strife: Ongoing since 1991.
    2. Food shortages: Persistent due to a collapse of agriculture and state infrastructure.
    3. Severe Famine: Highlighted in international news throughout 2022 and 2023 due to the historic "Horn of Africa" drought.

Correct Answer: D

This question tests the candidate's awareness of the "Horn of Africa" crisis, where the intersection of climate change (drought), conflict (Al-Shabaab), and global economic shocks (food prices) leads to severe humanitarian emergencies like famine.

Why This Question Was Asked

When BMC biodiversity committees was reported, it made BMC biodiversity committees a live current-affairs theme for Prelims.

Analysing the Question

The correct answer is C (Both 1 and 2). This question tests the understanding of the Biological Diversity Act, 2002, and its alignment with international environmental treaties.

Statement 1 is correct

The Nagoya Protocol (2010), a supplementary agreement to the Convention on Biological Diversity (CBD), focuses on "Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization" (ABS). In India, the Biodiversity Management Committees (BMCs) are statutory bodies established at the local level (Panchayats and Municipalities) under Section 41 of the Biological Diversity Act, 2002. They serve as the foundational units for implementing the Nagoya Protocol by maintaining People’s Biodiversity Registers (PBRs) and ensuring local communities benefit from the use of their traditional knowledge and resources.

Statement 2 is correct

Under the Biological Diversity Act, 2002, BMCs are empowered to manage local biological resources. Specifically, Section 41(3) of the Act mandates that BMCs may levy collection fees from any person for accessing or collecting any biological resource for commercial purposes from areas within its territorial jurisdiction. This power is a critical mechanism for the Access and Benefit Sharing (ABS) framework, ensuring that financial benefits flow back to the local conservators.

Option A: 1 only

• Incorrect.
  • While Statement 1 is factually accurate regarding the BMCs' role in the Nagoya Protocol, this option is incomplete because it ignores the legislative powers granted to BMCs described in Statement 2. UPSC often uses "1 only" to test if a student is aware of the international link but unaware of the specific legal powers granted by domestic legislation.

Option B: 2 only

• Incorrect.
  • While Statement 2 is factually accurate regarding the power to levy fees, this option is incomplete. It neglects the broader international context (Nagoya Protocol) that necessitates the existence of such committees. Students might choose this if they are familiar with the Act but fail to connect it to the global CBD framework.

Option C: Both 1 and 2

• Correct.
  • This is the correct choice as it recognizes both the international functional role (implementing the Nagoya Protocol) and the domestic legal authority (levying fees and managing ABS) of the Biodiversity Management Committees.

Option D: Neither 1 nor 2

• Incorrect.
  • This option is factually wrong because both statements are grounded in the Biological Diversity Act, 2002, and the Nagoya Protocol. UPSC includes this for students who might mistake BMCs for mere advisory bodies without actual fiscal or executive powers.

Key Takeaway:

The Biodiversity Management Committee (BMC) is the grassroots-level institution in India’s three-tier biodiversity regulatory structure (National-State-Local). Their dual role involves documenting traditional knowledge (PBRs) to meet Nagoya Protocol standards and exercising the statutory power to levy fees to ensure Access and Benefit Sharing (ABS).

Correct Answer: C

Option C follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

In 17 Jul 2022, All set for Presidential election; Droupadi Murmu has an edge over Yashwant Sinha put Presidential election 2022 in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option A

because, among the four statements provided, only Statement 4 is factually and conceptually correct according to the constitutional provisions governing the Presidential election in India.

The election of the President is governed by Articles 54 and 55 of the Indian Constitution. The value of an MLA's vote is determined by a specific formula: (Total population of the State as per the 1971 Census) divided by (Total number of elected members in the State Legislative Assembly × 1000). Because this value depends on the ratio of population to elective seats, small differences in these proportions across states result in varying vote values.

Statement 1

The members nominated to either House of the Parliament or the Legislative Assemblies of States are also eligible to be included in the Electoral College.

• Incorrect.
• Fact: Under Article 54, the Electoral College consists only of elected members of both Houses of Parliament and the elected members of the Legislative Assemblies of the States (including Delhi and Puducherry).
• Reason for error: Nominated members are excluded to ensure the President is chosen by representatives directly elected by the people. This is a common distractor because nominated members do participate in the removal (impeachment) of the President, leading to student confusion between election and impeachment rules.

Statement 2

Higher the number of elective Assembly seats, higher is the value of vote of each MLA of that State.

• Incorrect.
• Fact: The value of an MLA's vote is inversely proportional to the number of elective seats (since seats are in the denominator of the formula).
• Reason for error: If the population remains constant, increasing the number of seats actually decreases the value of each individual vote. UPSC tests the candidate’s mathematical understanding of the formula: $\text{Value} = \frac{\text{Total Population}}{\text{Elective Seats} \times 1000}$.

Statement 3

The value of vote of each MLA of Madhya Pradesh is greater than that of Kerala.

• Incorrect.
• Fact: Based on the 1971 Census (which is currently used), the vote value of an MLA from Madhya Pradesh is 131, whereas the vote value of an MLA from Kerala is 152.
• Reason for error: Students often assume that larger states geographically or by total population (like MP) automatically have higher vote values. However, Kerala has a higher population-to-seat ratio compared to Madhya Pradesh.

Statement 4

The value of vote of each MLA of Puducherry is higher than that of Arunachal Pradesh because the ratio of total population to total number of elective seats in Puducherry is greater as compared to Arunachal Pradesh.

• Correct.
• Fact: The vote value of an MLA from Puducherry is 16, while for Arunachal Pradesh, it is 8.
• Explanation: Even though both are small regions, Puducherry's 1971 population relative to its 30 seats results in a higher quotient than Arunachal Pradesh's 1971 population relative to its 60 seats. The statement correctly identifies the principle that the vote value is determined by the population-to-seat ratio.

Correct Answer: A

The Presidential election uses a system of proportional representation where the value of an MLA's vote depends on the 1971 population-to-seat ratio, ensuring that states with higher population density per representative have a weighted vote. Nominated members are strictly excluded from the election process.

Why This Question Was Asked

When National Handloom Day was reported, it made National Handloom Day a live current-affairs theme for Prelims.

Analysing the Question

Option A is correct.

This question tests the historical link between the modern Indian government's commemorative days and the Indian Independence Movement.

Statement I is correct

In 2015, the Government of India declared August 7th as National Handloom Day. The inaugural celebration was held in Chennai to generate awareness about the importance of the handloom industry and its contribution to the socio-economic development of the country.

Statement II is correct

The date August 7th was specifically chosen because of its historical significance. On August 7, 1905, the Swadeshi Movement was formally proclaimed at a massive meeting held in the Calcutta Town Hall. A key pillar of this movement was the boycott of foreign-made cloth and the promotion of indigenous (Swadeshi) products, particularly hand-woven Khadi and handloom textiles.

Option B

Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I. * Incorrect. * While both facts are true, this option incorrectly denies the causal link. UPSC often uses this as a distractor for students who know the facts but fail to connect the "Why" behind government policy. The declaration of Handloom Day was an explicit nod to the 1905 boycott of Manchester cloth.

Option C

Statement-I is correct but Statement-II is incorrect. * Incorrect. * This is incorrect because Statement II is factually accurate. Candidates often pick this if they confuse the 1905 meeting date with the actual Partition of Bengal (which took effect on October 16, 1905). However, the formal launch of the Swadeshi Movement indeed occurred on August 7.

Option D

Statement-I is incorrect but Statement-II is correct. * Incorrect. * This is incorrect because Statement I is a well-established current affairs fact. Since the first National Handloom Day in 2015, it has been an annual recurring event in India’s official calendar.

Key Takeaway

The Swadeshi Movement (August 7, 1905) aimed at self-reliance by promoting indigenous industries; the modern National Handloom Day commemorates this specific date to honor India's weaving heritage and its role in the freedom struggle.

Correct Answer: A

Therefore, Statement II is the correct explanation for Statement I.

Why This Question Was Asked

In 22 Jul 2022, Display Tricolour at home from August 13 to 15, PM Modi urges people put Har Ghar Tiranga in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Statement-I is incorrect

while Statement-II is correct.

The Flag Code of India, 2002, governs the display and specifications of the National Flag.

• Regarding Statement-II: According to Part 1, Section 1.1 of the Flag Code, the National Flag shall be rectangular in shape. The ratio of the length to the height (width) of the Flag must be 3:2. This is a fundamental structural requirement.
• Regarding Statement-I: The Flag Code specifies nine standard sizes. These are:
  1. 6300 × 4200 mm
  2. 3600 × 2400 mm
  3. 2700 × 1800 mm
  4. 1800 × 1200 mm
  5. 1350 × 900 mm
  6. 900 × 600 mm
  7. 450 × 300 mm
  8. 225 × 150 mm
  9. 150 × 100 mm

As seen from the official list, 600 mm × 400 mm is not one of the nine prescribed standard sizes. While it does maintain the 3:2 ratio, it is not a legally recognized "standard size" under the Code.

Option A: Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I

• Incorrect.
  • Reason: This option falls because Statement-I is factually wrong. UPSC uses this as a distractor by providing a size (600x400) that mathematically fits the 3:2 ratio, leading students to assume it must be a standard size. However, the Flag Code explicitly lists specific dimensions, and 600x400 is absent from that list.

Option B: Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I

• Incorrect.
  • Reason: Similar to Option A, this relies on Statement-I being true. Students often confuse 900x600 (a standard size) with 600x400.

Option C: Statement-I is correct but Statement-II is incorrect

• Incorrect.
  • Reason: This is a double error. It incorrectly validates the non-existent 600x400 size and incorrectly invalidates the universally known 3:2 ratio of the Indian flag.

Option D: Statement-I is incorrect but Statement-II is correct

• Correct.
  • Reason: Statement-I is wrong because 600 mm × 400 mm is not in the official list of nine standard sizes mandated by the Flag Code of India. Statement-II is a well-established legal and constitutional fact regarding the 3:2 ratio.

Correct Answer: D

The Flag Code of India, 2002, mandates a strict 3:2 length-to-width ratio and identifies nine specific standard sizes; a dimension is not "standard" simply because it maintains the ratio—it must specifically match the dimensions listed in the Code.

Why This Question Was Asked

When भारत सरकार was reported, it made Constitution Day a live current-affairs theme for Prelims.

Analysing the Question

Option C

. This is because Statement-I is factually accurate, while Statement-II contains a significant chronological error regarding the history of the Constituent Assembly.

Statement-I is correct

In 2015, the Government of India (Ministry of Social Justice and Empowerment) notified November 26 as 'Constitution Day' (Samvidhan Divas). This date was chosen to commemorate the adoption of the Constitution of India and to spread awareness about the importance of the Constitution and the thoughts of Dr. B.R. Ambedkar.

Statement-II is incorrect

While Dr. B.R. Ambedkar was indeed the Chairman of the Drafting Committee, the committee was not set up on November 26, 1949. The Drafting Committee was established on August 29, 1947, shortly after India's independence. By November 26, 1949, the drafting process was already complete, and the Constituent Assembly formally adopted and enacted the Constitution.

Option A: Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I

• Incorrect.
  • This option is incorrect because Statement-II is factually wrong. Even if the date in Statement-II were correct, the setting up of a committee is not the reason we celebrate Constitution Day; we celebrate it because the final product was adopted on that day.

Option B: Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I

• Incorrect.
  • This is a common distractor. Students often recognize both facts (Drafting Committee and 26th November) as "related to the Constitution" and assume both statements are true without checking the specific dates.

Option C: Statement-I is correct but Statement-II is incorrect

• Correct.
  • As established, Statement-I aligns with the 2015 government notification. Statement-II fails because it confuses the adoption date (Nov 26, 1949) with the formation date of the Drafting Committee (Aug 29, 1947). This tests the candidate's precision regarding the timeline of the constitutional making process.

Option D: Statement-I is incorrect but Statement-II is correct

• Incorrect.
  • This option is wrong because Statement-I is a standard fact regarding modern Indian commemorative days, and Statement-II is clearly invalidated by historical records regarding the 1947 appointment of the Drafting Committee.

Key Takeaway:

Constitution Day (Nov 26) marks the adoption of the Constitution in 1949, not the formation of the Drafting Committee, which occurred much earlier in August 1947. Always distinguish between the dates of commencement (Jan 26, 1950), adoption (Nov 26, 1949), and committee formation (Aug 29, 1947).

Option C follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

In 27 Jan 2022, Swiss gold exports to China and India hit multi-year highs put Switzerland gold exports in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option C is correct because Statement-I is a factual reality of global trade, while Statement-II is factually incorrect regarding the ranking of global gold reserves.

Statement-I is Correct

Switzerland is indeed a global hub for gold. It is one of the leading exporters of gold in terms of value. This status is not derived from domestic mining (which is negligible) but from its world-class refining industry. Switzerland imports raw dore (unrefined gold) from various countries, refines it to 999.9 purity, and re-exports it. Major refineries like Valcambi, PAMP, and Argor-Heraeus are based there. In many years, gold accounts for a significant percentage of Switzerland’s total export value.

Statement-II is Incorrect

Switzerland does not have the second-largest gold reserves in the world. According to the World Gold Council, the ranking of gold reserves (as of 2023) is as follows: 1. United States (~8,133 tonnes) 2. Germany (~3,353 tonnes) 3. Italy (~2,452 tonnes) 4. France (~2,437 tonnes) 5. Russia (~2,330 tonnes) Switzerland typically ranks 7th or 8th globally (with approximately 1,040 tonnes). Therefore, Statement-II is factually false.

Option A

Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I * Incorrect. * This option is incorrect because Statement-II is false. Even if Statement-II were true, a country's reserves (gold held by the Central Bank) do not necessarily dictate its export volume. Export volume depends on industrial refining capacity and trade infrastructure, not just central bank holdings.

Option B

Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I * Incorrect. * This is a common distractor for candidates who know Switzerland is "good with gold" but are unsure of the exact rankings. It fails because it assumes Statement-II is a true fact, when in reality, Switzerland's reserves are far behind those of the US and Germany.

Option C

Statement-I is correct but Statement-II is incorrect * Correct. * As established, Switzerland is a leading exporter due to its refining industry (Statement-I is true). However, it ranks 7th/8th in reserves, not 2nd (Statement-II is false).

Option D

Statement-I is incorrect but Statement-II is correct * Incorrect. * This option reverses the factual accuracy. It is a distractor for those who might mistakenly believe Switzerland lacks trade volume or overestimates its national gold holdings.

Correct Answer: C

Switzerland's dominance in the gold market is due to its commercial refining and processing capacity, not its national central bank reserves. While it houses some of the world's largest gold refineries, its official gold reserves rank well below the United States and major Eurozone economies.

Why This Question Was Asked

When India-EU Trade Technology Council was reported, it made India-EU Trade Technology Council a live current-affairs theme for Prelims.

Analysing the Question

Statement-I is correct.

The U.S.-EU Trade and Technology Council (TTC) was officially launched during the U.S.-EU Summit in Brussels on June 15, 2021. It serves as a high-level forum for the two partners to coordinate approaches to key global trade, economic, and technology issues. For India-specific context, it is worth noting that India is only the second partner (after the USA) with whom the EU has established such a Council (the India-EU TTC was launched in 2022).

Statement-II is incorrect.

The stated objective of the TTC is not to "control" technological progress or physical productivity in a restrictive or monopolistic sense. Instead, the official claim and mandate of the TTC are to foster transatlantic cooperation, promote democratic values, ensure supply chain resilience, and develop shared standards for emerging technologies (like AI and semiconductors). The language used in Statement-II—"bringing progress under their control"—implies a coercive or mercantilist intent which contradicts the official diplomatic objectives of facilitating open markets and innovation-led growth.

Option A: Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I

• Incorrect.
  • While Statement-I is a factual occurrence, Statement-II mischaracterizes the intent of the partnership. UPSC often uses "strong" or "negative" words like "control" to make a statement incorrect. The TTC is framed as a collaborative platform, not a mechanism for global technological hegemony.

Option B: Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I

• Incorrect.
  • This is a common distractor for students who recognize the TTC exists but are unsure of its specific ideological framing. However, since Statement-II is factually false regarding the declared goals of the US and EU, this option cannot be correct.

Option C: Statement-I is correct but Statement-II is incorrect

• Correct.
  • As established, the TTC was indeed launched recently (2021). The goals of the TTC are publicly documented as: strengthening trade links, protecting human rights in the digital space, and coordinating on tech regulation—not "controlling" productivity. Statement-II is a classic "trap" statement using cynical phrasing that does not align with official international agreements.

Option D: Statement-I is incorrect but Statement-II is correct

• Incorrect.
  • This option is wrong because Statement-I is a well-documented diplomatic event. If a student misses current affairs regarding major bilateral councils, they might fall for this, but the TTC is a cornerstone of the Biden administration's engagement with Europe.

Key Takeaway:

The Trade and Technology Council (TTC) is a strategic platform for cooperation on emerging technologies and supply chains; its goals are rooted in standard-setting and democratic alignment, rather than the centralized control of global productivity. Always be wary of extreme or restrictive verbs in Statement-II of UPSC "Assertion-Reasoning" style questions.

Correct Answer: C

Option C follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

In 31 Mar 2023, Government vows swifter nod for exporters put Record exports FTP 2023 in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option D is correct

because Statement-I is a factual error, while Statement-II accurately describes the current industrial policy environment in India.

Statement-I is Incorrect

According to the World Trade Organization (WTO) World Trade Statistical Review 2023 and the Economic Survey 2022-23, India’s share in global merchandise (goods) exports stands at approximately 1.8%. The figure of 3.2% mentioned in the question is closer to India's share in global commercial services exports (which is roughly 4%), but definitely not for goods.

Statement-II is Correct

The 'Production-Linked Incentive' (PLI) scheme, launched in 2020 across 14 key sectors (like electronics, pharmaceuticals, and automobiles), has seen significant participation from both domestic players (e.g., Tata, Reliance) and foreign multinationals (e.g., Apple’s contract manufacturers like Foxconn and Wistron, Samsung). This scheme incentivizes incremental sales from products manufactured in domestic units.

Option A: Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I

• Incorrect.
  • Error: This option assumes Statement-I is true. UPSC often uses "plausible-sounding" percentages. Since India is a large economy, a student might guess 3.2% is a reasonable figure, but in reality, India's goods export footprint remains below 2%.

Option B: Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I

• Incorrect.
  • Error: Similar to Option A, this relies on Statement-I being true. UPSC includes this because even if a student knows both facts are potentially true, they often struggle with the "logical link" between them. Here, the premise fails at the factual level of Statement-I.

Option C: Statement-I is correct but Statement-II is incorrect

• Incorrect.
  • Error: This reverses the factual validity of both statements. Statement-II is a widely publicized flagship scheme of the Government of India with high corporate participation, making it highly unlikely to be incorrect.

Option D: Statement-I is incorrect but Statement-II is correct

• Correct.
  • Reasoning: As established, India's share in global goods exports is ~1.8%, making Statement-I false. Simultaneously, the PLI scheme is a cornerstone of the 'Atmanirbhar Bharat' initiative and has successfully attracted both local and foreign investments, making Statement-II true.

Key Takeaway:

India’s share in global goods exports is approximately 1.8%, whereas its share in services exports is significantly higher (approx. 4%). The PLI scheme is a major policy tool designed to bridge this gap by attracting both global and local manufacturing investment.

Correct Answer: D

Option D follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

In 20 Aug 2022, Greece's exit from enhanced EU scrutiny ends 12 years of pain: PM put EU Stability Growth Pact in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

The correct answer is A: Only one. This is because the Stability and Growth Pact (SGP) is strictly a set of fiscal rules designed to ensure that countries in the European Union (EU) pursue sound public finances and coordinate their fiscal policies.

Introduced in 1997 (based on the Maastricht Treaty criteria), the SGP aims to safeguard the stability of the Economic and Monetary Union (EMU). It specifically mandates two main constraints:

1. Budget Deficit: A member state's annual budget deficit must not exceed 3% of its Gross Domestic Product (GDP).
2. Public Debt: A member state's national debt must not exceed 60% of its GDP.

Only statement 1 aligns with these fiscal objectives. Statements 2 and 3 refer to infrastructure and technology sharing, which are governed by other EU mechanisms (such as the Connecting Europe Facility or Horizon Europe) but are entirely outside the scope of the Stability and Growth Pact.

Option A: Only one

• Correct.
  • As analyzed, only statement 1 is factually correct. The SGP is a "fiscal rulebook." Since only one of the three provided statements is true, Option A is the right choice under the new UPSC "Only/All" pairing format.

Option B: Only two

• Incorrect.
  • This option would be correct if two statements were true. However, since the SGP has no legal or functional mandate regarding "infrastructure sharing" (Statement 2), this option is false. Analysts often confuse the SGP with general EU integration policies, but its focus is purely macroeconomic and budgetary.

Option C: All three

• Incorrect.
  • This is a common distractor for students who assume that "European Union" pacts are always broad, "catch-all" agreements covering economy, technology, and infrastructure. Statement 3 (technology sharing) is incorrect because technology transfer is handled through research frameworks (like Horizon Europe) and the Digital Single Market, not the SGP.

Option D: None

• Incorrect.
  • This option is incorrect because Statement 1 is a verified fact. The SGP was specifically created to prevent "free-riding" where one country’s reckless deficit spending could devalue the Euro and harm the entire Eurozone.

Comparison of Statements

1. Statement 1: Limits the levels of the budgetary deficit... — Correct. This is the primary objective of the SGP to ensure fiscal discipline.
2. Statement 2: Makes the countries... share their infrastructure facilities. — Incorrect. While the EU has "Trans-European Networks" (TEN), the SGP does not mandate physical infrastructure sharing.
3. Statement 3: Enables the countries... to share their technologies. — Incorrect. Technology sharing is part of the EU's Innovation Union and specific trade agreements, not the fiscal SGP.

Key Takeaway

The Stability and Growth Pact (SGP) is a fiscal monitoring tool used by the EU to ensure that member states maintain budget deficits below 3% and debt below 60% of GDP to protect the Euro's stability. It does not cover infrastructure or technology.

Correct Answer: A

Option A follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

In 1 Jan 2023, Brazil's Lula calls for peace at meetings with Russia, Ukraine representatives put Brazil Lula Global Compact in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Correct Answer Analysis: D (None)

The correct answer is D because all three statements provided in the question are factually incorrect. The Global Compact for Safe, Orderly and Regular Migration (GCM), adopted in December 2018 (Marrakesh, Morocco), is a landmark intergovernmental agreement. However, it faced significant opposition from several countries, is explicitly non-binding in nature, and focuses strictly on international migration rather than internal displacement.

Statement 1: Recently, all the countries of the United Nations have adopted the first-ever compact for international migration, the 'Global Compact for Safe, Orderly and Regular Migration (GCM)'.

• Incorrect.
• Reason: While the GCM was adopted by a majority (164 countries initially), it was not adopted by all UN member states. Several prominent countries, including the United States, Hungary, Israel, Czech Republic, and Poland, refused to join or vote for the compact, citing concerns over national sovereignty and border control.
• **Exam trap: ** UPSC often uses absolute terms like "all" or "every" to test a candidate's awareness of geopolitical nuances. Even though it was a major UN initiative, it was not universal.

Statement 2: The objectives and commitments stated in the GCM are binding on the UN member countries.

• Incorrect.
• Reason: The GCM is explicitly a non-legally binding cooperative framework. The text of the compact emphasizes the "sovereign right of States to determine their national migration policy." It functions as a set of best practices and 23 objectives, but it does not impose legal obligations on signatories.
• **Exam trap: ** This is a classic distractor testing the understanding of the nature of international law—distinguishing between "Hard Law" (Treaties/Conventions) and "Soft Law" (Compacts/Declarations).

Statement 3: The GCM addresses internal migration or internally displaced people also in its objectives and commitments.

• Incorrect.
• Reason: The GCM focuses strictly on international migration. Internal migration and Internally Displaced Persons (IDPs) are governed by different frameworks, such as the UN Guiding Principles on Internal Displacement. The GCM specifically targets the management of movement between borders, not within them.
• **Exam trap: ** This tests the candidate’s precision regarding the scope of the institution. Confusing international migration with internal displacement is a common error among students.

Analysis of the Options:

Option A, B, C

Incorrect because these options assume that at least one, two, or all statements are true. Since all three statements contain factual inaccuracies (universality, legal nature, and scope), these options are eliminated.

Option D

Correct, as none of the provided statements are true.

Key Takeaway:

The Global Compact for Migration (GCM) is the first intergovernmentally negotiated agreement on international migration; however, it is non-binding, was not signed by all UN members, and does not cover internal displacement.

Correct Answer: D

Option D follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

In 14 Aug 2020, Explained: Israel and UAE normalise relations; here’s what it means for the Middle East put Abraham Accords Israel in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option C

. This question tests a candidate's understanding of contemporary Middle Eastern geopolitics and its historical trajectory.

Statement I is correct

Israel has successfully established diplomatic relations with several Arab states over different periods. Historically, Egypt signed a peace treaty in 1979, followed by Jordan in 1994. More recently, in 2020, the Abraham Accords (brokered by the US) led to the normalization of ties between Israel and the United Arab Emirates (UAE), Bahrain, and later Morocco.

Statement II is incorrect

While the Arab Peace Initiative (API) was indeed proposed and endorsed by Saudi Arabia and adopted by the Arab League (at the Beirut Summit in 2002), it was never signed by Israel. The API offered Israel full normalization of relations with all 22 Arab states in exchange for a full withdrawal from occupied territories (including the West Bank and Gaza), a "just settlement" for Palestinian refugees, and the establishment of a Palestinian state with East Jerusalem as its capital. Israel rejected the terms, citing security concerns and the "right of return" clause, meaning the document remained a proposal rather than a signed agreement.

Option A: Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I.

• Incorrect.
  • Reason: This option is incorrect because Statement II is factually wrong. Furthermore, even if Statement II were true, the recent diplomatic breakthroughs (like the Abraham Accords) actually bypassed the conditional logic of the Arab Peace Initiative (which required a Palestinian state first) rather than being explained by it.

Option B: Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I.

• Incorrect.
  • Reason: This option incorrectly assumes Statement II is a fact. UPSC uses this as a distractor for students who know the Arab Peace Initiative exists but are unsure whether it was a signed treaty or a unilateral proposal.

Option C: Statement-I is correct but Statement-II is incorrect.

• Correct.
  • Reason: As established, Israel does have diplomatic ties with specific Arab nations (Factually correct). However, the Arab Peace Initiative remains an unsigned proposal from the Arab League side that Israel has not accepted or signed (Factually incorrect).

Option D: Statement-I is incorrect but Statement-II is correct.

• Incorrect.
  • Reason: Statement I is a widely known geopolitical fact (normalization with UAE/Bahrain was major news in 2020-21). Stating Statement I is incorrect would contradict the reality of current Middle Eastern diplomacy.

Key Takeaway:

The core concept tested is the distinction between unilateral peace proposals (like the 2002 Arab Peace Initiative) and bilateral diplomatic treaties (like the 1979 Egypt-Israel Treaty or the 2020 Abraham Accords). While the Arab League proposed a "land-for-peace" deal, Israel's recent diplomatic gains have occurred through separate, specific agreements.

Correct Answer: C

Why This Question Was Asked

In 6 Aug 2021, Khel Ratna Award renamed after Dhyan Chand put Khel Ratna rename Dhyan Chand in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Correct Answer Analysis: B (Only two)

The National Sports Awards are conferred annually by the Ministry of Youth Affairs and Sports. In 2023, the UPSC shifted its pattern towards testing the specific technical definitions of these awards. Based on the official guidelines issued by the Government of India, only

Pair 1

and Pair 3 are correctly matched.

Pairs 2 and 4 are incorrectly matched because they interchangeable or misidentify the primary objective of the specific award. Therefore, since exactly two pairs are correct, Option B is the right answer.

1. Major Dhyan Chand Khel Ratna Award

• ✅ CORRECT
• This is the highest sporting honour in India. According to the scheme guidelines, it is awarded for the "most spectacular and outstanding performance by a sportsperson over a period of the last four years." It was formerly known as the Rajiv Gandhi Khel Ratna Award before being renamed in 2021.

2. Arjuna Award

• ❌ INCORRECT
• The Error: The description provided ("lifetime achievement") is incorrect for the Arjuna Award.
• The Fact: The Arjuna Award is given for "good performance over a period of the previous four years" and for showing qualities of leadership, sportsmanship, and a sense of discipline.
• UPSC Distractor: UPSC substituted the definition of the Dhyan Chand Award for Lifetime Achievement (not to be confused with the Khel Ratna) into the Arjuna Award slot. The Dhyan Chand Award is the one specifically meant for lifetime contribution.

3. Dronacharya Award

• ✅ CORRECT
• Instituted in 1985, this award is given to coaches who have successfully trained sportspersons or teams and enabled them to achieve outstanding results in international events. It recognizes the "outstanding and meritorious work" done by coaches on a consistent basis.

4. Rashtriya Khel Protsahan Puraskar

• ❌ INCORRECT
• The Error: It does not recognize individual sportspersons after retirement.
• The Fact: This award is conferred upon corporate entities (both private and public sector), Sports Control Boards, and NGOs that have played a visible role in the promotion and development of sports.
• UPSC Distractor: The description provided in the question—"contribution made by sportspersons even after their retirement"—is actually the mandate for the Dhyan Chand Award for Lifetime Achievement in Sports and Games.

Key Takeaway:

The UPSC tests the ability to distinguish between awards for performance (Khel Ratna/Arjuna), instruction (Dronacharya), lifetime contribution (Dhyan Chand Award), and institutional promotion (Rashtriya Khel Protsahan Puraskar). Pay close attention to the timeframes (4 years) and the nature of the recipient (individual vs. corporate).

Correct Answer: B

Therefore, since exactly two pairs are correct, Option B is the right answer.

Why This Question Was Asked

In 21 Jul 2022, Thambi, the Chess Olympiad mascot, is here to paint Tamil Nadu ‘black and white’ put Chess Olympiad India in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

The correct answer is B (Only two). This is because, of the four statements provided regarding the 44th Chess Olympiad held in 2022, only Statement 1 and Statement 2 are factually accurate.

The 44th Chess Olympiad was a landmark event for India as it was the first time the country hosted this prestigious tournament. It took place in Mamallapuram, Chennai. Statement 1 is correct. The event’s mascot, 'Thambi' (a knight dressed in traditional Tamil attire, 'Veshti' and 'Sattai'), became an iconic symbol of the event. Statement 2 is correct.

However, Statements 3 and 4 are incorrect because the names of the trophies for the Open and Women’s sections have been swapped. The Hamilton-Russell Cup is awarded to the Open section, and the Vera Menchik Cup is awarded to the Women’s section. Since only two statements are correct, Option B is the right choice.

Statement 1

It was the first time that Chess Olympiad was held in India. * Correct. * Reasoning: While India has a rich history in chess, it had never hosted the Olympiad before. The 2022 edition was originally scheduled to be held in Russia but was moved to Chennai, India, following the geopolitical situation in Ukraine.

Statement 2

The official mascot was named 'Thambi'. * Correct. * Reasoning: 'Thambi' (meaning 'younger brother' in Tamil) was the official mascot. It depicted a chess knight with folded hands (Vanakkam), wearing traditional Tamilian attire.

Statement 3

The trophy for the winning team in the open section is the Vera Menchik Cup. * Incorrect. * Reasoning: The Vera Menchik Cup is actually the trophy for the Women’s section. It is named after the first Women's World Chess Champion. UPSC uses this "swap" technique frequently to test the precision of a candidate's memory.

Statement 4

The trophy for the winning team in the women's section is the Hamilton-Russell Cup. * Incorrect. * Reasoning: The Hamilton-Russell Cup is the trophy for the Open section. It was donated by Frederick Hamilton-Russell for the first official Olympiad in 1927. Similar to Statement 3, the error lies in the misattribution of the trophy name to the wrong category.

Verification of Options:

Option A

(Only one) — Incorrect, as two statements (1 & 2) are true.

Option B

(Only two) — CORRECT, as statements 1 and 2 are right.

Option C

(Only three) — Incorrect, as two statements (3 & 4) are false.

Option D

(All four) — Incorrect.

Key Takeaway

This question tests the candidate's attention to detail regarding major international sporting events held in India. A common UPSC trap is swapping names or definitions (like the trophies in this case), requiring students to be precise during revision.

Correct Answer: B

Option B follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

In 19 Apr 2022, Russian offensive in eastern Ukraine has begun, says Zelensky put Conflict regions Donbas Tigray in the news — the kind of headline UPSC often turns into a Prelims question.

Explanation

The correct answer is D (None). This question tests a candidate’s awareness of contemporary geopolitical crises and major conflict zones. In this specific question, every single pair provided is incorrectly matched. Each location mentioned has been frequently cited in international news between 2021 and 2023 due to civil wars, separatist movements, or territorial disputes; however, they have been swapped with different regions or countries to test the candidate’s precision.

1. Pair 1: Donbas — Syria

• ❌ INCORRECT
• Factual Error: The Donbas region is located in Ukraine, not Syria. It comprises the Donetsk and Luhansk oblasts. This region has been the center of a major conflict involving pro-Russian separatists since 2014 and became the primary theater of the full-scale Russian invasion in 2022.
• UPSC Distractor Logic: UPSC often pairs regions of high-intensity conflict together. Since Syria has also been a major conflict zone for over a decade, candidates who are not precise with geographical mapping might confuse different areas of global unrest.

2. Pair 2: Kachin — Ethiopia

• ❌ INCORRECT
• Factual Error: Kachin State is located in Myanmar. It is the northernmost state of Myanmar and has seen prolonged conflict between the Kachin Independence Army (KIA) and the Myanmar military (Tatmadaw).
• UPSC Distractor Logic: Ethiopia has faced significant internal conflict in recent years (specifically the Tigray war). By placing an Asian conflict zone (Kachin) next to an African country (Ethiopia), the examiner tests whether the candidate can distinguish between different ethnic insurgencies across continents.

3. Pair 3: Tigray — North Yemen

• ❌ INCORRECT
• Factual Error: The Tigray region is located in Ethiopia, not Yemen. The Tigray War (2020–2022) was a major armed conflict between the Ethiopian federal government and the Tigray People's Liberation Front (TPLF).
• UPSC Distractor Logic: Yemen has its own significant conflict (the Houthi insurgency), making it a plausible but incorrect location for someone who reads news headlines superficially. By swapping "Ethiopia" from the second pair into the third pair's logic, the examiner creates a web of confusion.

4. Option D: None

• ✅ CORRECT
• Since all three pairs (Donbas-Ukraine, Kachin-Myanmar, and Tigray-Ethiopia) are mismatched in the question, Option D is the only logically sound choice.

Takeaway:

This question tests the ability to accurately link current affairs with world geography. In UPSC Prelims, "Conflict Zones" or "Places in News" are high-priority topics; candidates must maintain a mental map of global hotspots to avoid falling for "cross-matching" traps where correct countries and correct regions are both present but incorrectly paired.

Why This Question Was Asked

In 12 Feb 2022, African Union | Amidst a wave of coups and a pandemic put Sahel coups Chad Mali in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option D: Successful coups

.

Between 2020 and 2023, the regions of West Africa, Central Africa, and the Sahel witnessed a significant democratic backsliding, often referred to by international analysts as the "coup contagion." All four countries mentioned—Chad, Guinea, Mali, and Sudan—experienced unconstitutional changes of power led by military leaders:

• Mali (August 2020 & May 2021): Colonel Assimi Goïta led two coups in less than a year, first ousting President Ibrahim Boubacar Keïta and later the transitional government.
• Chad (April 2021): Following the death of long-time President Idriss Déby on the battlefield, the military installed his son, Mahamat Idriss Déby, as head of a Transitional Military Council, bypassing the constitutional line of succession.
• Guinea (September 2021): Special forces commander Colonel Mamady Doumbouya overthrew President Alpha Condé following protests against Condé’s bid for a third term.
• Sudan (October 2021): General Abdel Fattah al-Burhan led a military takeover, dissolving the power-sharing Sovereign Council that had been established after the 2019 ousting of Omar al-Bashir.

These events led to the suspension of these nations from the African Union (AU) and the Economic Community of West African States (ECOWAS).

Option A: Discovery of rich deposits of rare earth elements

• Incorrect.
  • While several African nations (like DRC or Namibia) are being explored for critical minerals, there was no specific, simultaneous major discovery of Rare Earth Elements (REEs) that linked these four specific countries in recent headlines. This is a "distractor" because the global race for green energy minerals often involves African geopolitics.

Option B: Establishment of Chinese military bases

• Incorrect.
  • Currently, China’s only official overseas military base in Africa is in Djibouti (established 2017). While there are rumors regarding a potential base in Equatorial Guinea, no such bases have been established in Chad, Guinea, Mali, or Sudan. This option exploits the common UPSC theme of Chinese "String of Pearls" or global expansion.

Option C: Southward expansion of Sahara Desert

• Incorrect.
  • Desertification is a real environmental threat in the Sahel (the "Great Green Wall" initiative aims to combat this). However, this is a long-term ecological trend rather than a specific event that caused these four countries to "catch international attention" simultaneously in the "recent years" context of political news.

Correct Answer: D

The UPSC often tests "thematic commonalities" in geography and international relations; in this case, the central theme was the instability of the Sahel region and the resurgence of military interventions in governance.

Why This Question Was Asked

When National Green Hydrogen Policy was reported, it made National Green Hydrogen Policy a live current-affairs theme for Prelims.

Analysing the Question

Correct Answer Analysis: Option C (All three)

Green hydrogen, produced through the electrolysis of water using renewable energy, is considered the cornerstone of India’s National Green Hydrogen Mission (2023). Its primary utility lies in "hard-to-abate" sectors where direct electrification is technically difficult or impossible.

1. Fertilizer Plants: Currently, the fertilizer industry is one of the largest consumers of hydrogen. Hydrogen is reacted with nitrogen to produce Ammonia ($NH_3$) (Haber-Bosch process), which is the base for urea. At present, "Grey Hydrogen" (derived from natural gas) is used. Replacing this with Green Hydrogen allows for the production of "Green Ammonia," completely decarbonizing the feedstock.
2. Oil Refineries: Refineries use vast amounts of hydrogen for hydroalkylation and hydrodesulfurization (removing sulfur from crude oil to meet fuel standards like BS-VI). Transitioning from fossil-fuel-based hydrogen to Green Hydrogen in these chemical processes is a primary goal for decarbonizing the petroleum sector.
3. Steel Plants: The steel industry is a massive carbon emitter due to the use of coking coal. Green hydrogen can act as a reducing agent in the Direct Reduced Iron (DRI) process. By replacing carbon monoxide (from coal/gas) with hydrogen, the byproduct released is water vapor instead of $CO_2$.

Option A: Only one

• Incorrect.
  • This is incorrect because it underestimates the versatile chemical properties of hydrogen. Hydrogen is not just an energy carrier; it is a critical industrial reactant. Treating it as relevant to only one sector (like just fertilizers) ignores its fundamental role in metallurgy and chemical refining.

Option B: Only two

• Incorrect.
  • This is a common distractor for candidates who might recognize hydrogen's role in the chemical sector (Fertilizers and Oil) but are unaware of the technological shift in the "Green Steel" industry. Recent advancements in DRI technology have made Green Hydrogen a viable replacement for coal in steelmaking.

Option C: All three

• Correct.
  • All three industries are specifically identified as "priority sectors" under the Global and National Green Hydrogen strategies. They are "heavy industries" because their high-heat requirements and chemical feedstock needs cannot be met by lithium-ion batteries or solar panels alone.

Option D: None

• Incorrect.
  • This is factually wrong as it contradicts international climate agreements (Paris Agreement) and India's "Net Zero by 2070" target, which relies heavily on hydrogen for industrial decarbonization.

Key Takeaway

Green hydrogen is a critical substitute for fossil fuels in "hard-to-abate" sectors (Fertilizer, Steel, and Refining) where it serves a dual purpose as both a clean chemical feedstock and a carbon-free reducing agent.

Correct Answer: C

Option C follows once each statement or pair is checked against standard syllabus facts.

Why This Question Was Asked

In 30 Nov 2022, Narendra Modi | ‘India’s G20 agenda will be inclusive, ambitious, action-oriented, and decisive’ put G20 India presidency in the news — the kind of headline UPSC often turns into a Prelims question.

Analysing the Question

Option C (Both 1 and 2)

is correct because both statements accurately reflect the historical evolution and current strategic agenda of the G20.

Statement 1

The G20 (Group of Twenty) was established in 1999 in the aftermath of the Asian Financial Crisis. Initially, it was designed as a forum for Finance Ministers and Central Bank Governors from 19 countries and the European Union to discuss international financial stability. It was only elevated to a "Leaders' Summit" level in 2008 as a response to the global financial crisis.

Statement 2

During India’s G20 Presidency (2023), Digital Public Infrastructure (DPI) was a central pillar of the "New Delhi Leaders’ Declaration." India actively promoted its "India Stack" model (Aadhaar, UPI, DigiLocker) as a global framework for financial inclusion and efficient governance.

Option A: 1 only

• Incorrect.
  • While Statement 1 is factually true, this option is incomplete because Statement 2 is also correct. UPSC often provides this option as a distractor for candidates who are familiar with the history of the G20 but have not tracked recent current affairs or India’s specific presidency priorities.

Option B: 2 only

• Incorrect.
  • While Statement 2 is factually true, this option is incomplete because Statement 1 is also correct. This distractor targets students who are aware of recent news regarding India's G20 summit but might have forgotten the original ministerial mandate of the group from 1999.

Option C: Both 1 and 2

• Correct.
  • This option correctly identifies that the G20 began as a technical financial forum (Statement 1) and that India leveraged its 2023 presidency to champion Digital Public Infrastructure (Statement 2). The synchronization of historical context and current policy priorities makes this the comprehensive choice.

Option D: Neither 1 nor 2

• Incorrect.
  • This option is entirely incorrect as both statements are established facts. UPSC includes this for candidates who might doubt the "originally established" claim of Statement 1 or fail to recognize DPI as an official G20 priority area.

Key Takeaway:

The G20 evolved from a Finance-led forum (1999) to a Leaders' Summit (2008), and India’s presidency successfully prioritized Digital Public Infrastructure (DPI) as a global standard for inclusive growth.

Correct Answer: C

Option C follows once each statement or pair is checked against standard syllabus facts.
