GS Paper 3 practice questions for UPSC Mains 2026.

• Financial exclusion converts a temporary shock into permanent disadvantage, which makes it a social question.
• Accounts in women's own names shift intra-household control — the strongest documented Jan Dhan effect.
• The architecture rests on the JAM trinity layered with UPI, Business Correspondents, RuPay and now ULI.
• The RBI FI-Index was introduced in 2021, runs 0 to 100, and is published annually for the year ending March.
• Three weighted dimensions: Access 35 per cent, Usage 45 per cent, Quality 20 per cent, across 97 indicators.
• It has no base year, so values are directly comparable across years.
• Limits: national composite hides state variation, dormant accounts still count as access, and demand-side capability is under-measured.

• A Technology Mission is a time-bound structure pulling research, extension, inputs and procurement into one command chain.
• The Technology Mission on Oilseeds (1986) was the template and sharply cut edible oil import dependence.
• The Technology Mission on Cotton (2000) with Bt cotton moved India from importer to leading exporter.
• The National Food Security Mission (2007) followed the 2006 crisis, later extended to nutri-cereals.
• Foodgrain output rose from about 51 million tonnes in 1950-51 to over 300 million tonnes.
• Missions delivered availability and stability; access and especially utilisation remain weak.
• They succeed where the constraint is technological and stall where it is institutional — marketing, credit, tenancy.

• Infrastructure in fragile zones often creates hazard rather than merely being exposed to it.
• Joshimath (2023) subsidence involved tunnelling and unregulated construction on old landslide debris.
• Odisha's cyclone deaths fell from roughly 10,000 in 1999 to single digits — infrastructure as risk reduction.
• Project-by-project appraisal is the core failure; cumulative basin-scale assessment is rare.
• Ecologically sensitive zone notifications function as paper categories rather than siting constraints.
• Environmental clearance runs after alignment selection, which is too late to change the risk.
• The Disaster Management Act's prevention mandate is weaker in practice than its response machinery.

• Adopted at CBD COP15 in Montreal in December 2022, replacing the unmet Aichi Targets.
• 2050 Vision of living in harmony with nature; 2030 Mission to halt and reverse biodiversity loss.
• Four long-term goals and 23 action-oriented targets for 2030.
• Target 3 is '30 by 30' — conserve 30 per cent of terrestrial and marine areas by 2030.
• Target 19 seeks 200 billion dollars a year, including 30 billion in international flows to developing countries.
• India's protected areas cover about 5.3 per cent of area, so OECMs are decisive rather than supplementary for Target 3.
• The framework has no compliance mechanism, which is the same weakness that defeated Aichi.

• Indian farmers receive roughly a third of the consumer rupee for perishables and about half for cereals.
• The credit interlock — the commission agent is also the lender — is the single most damaging feature.
• APMC created monopsony through mandatory sale in notified areas and licensing barriers to new traders.
• Average holding of 1.08 hectares leaves marketable surpluses too small to bargain with.
• e-NAM attacks information asymmetry through unified electronic bidding across mandis.
• Integrated assaying is what makes remote bidding possible; without grading, an online platform is only a listing board.
• E-commerce cannot build cold chains or dissolve the credit interlock, so it must be sequenced with infrastructure.

• India is the second-largest producer of fruits and vegetables and loses a large share to perishability.
• Delayed ripening works by suppressing ethylene biosynthesis (ACC synthase, ACC oxidase) or cell-wall softening enzymes.
• Transgenic delayed-ripening papaya and work on tomato and banana are the Indian instances.
• The farmer gain is a longer selling window, which removes the distress-sale compulsion.
• Microbial enzymes — pectinase, cellulase, amylase — raise juice extraction yield and clarify product.
• Higher extraction yield lets a processor pay more per tonne, which is what makes near-orchard processing viable.
• Both benefits are conditional on a cold chain, a nearby processor and regulatory clearance existing.

• Thermal reactors use a moderator to slow neutrons; fast reactors have none and run on fast neutrons.
• Fast reactors use plutonium-uranium MOX fuel with a depleted U-238 blanket that breeds Pu-239.
• Liquid sodium coolant is used because water would moderate neutrons; sodium reacts violently with water and air.
• Criticality is k = 1, the self-sustaining steady state — the normal operating condition, not a hazard.
• The 500 MWe PFBR built by BHAVINI attained first criticality on 6 April 2026, over fifteen years late.
• Final fuel loading began 18 October 2025 after AERB clearance.
• Its significance is fuel-cycle: it opens Stage II and is the bridge to using India's large thorium reserves.

• Disinformation mobilises crowds faster than administration can respond, which makes it a public-order problem.
• The IT Rules 2021 were framed under Section 87 of the IT Act 2000, replacing the 2011 guidelines.
• Non-compliance costs an intermediary its Section 79 safe harbour.
• Significant Social Media Intermediaries must appoint a Chief Compliance Officer, Nodal Contact Person and Resident Grievance Officer.
• Traceability of the first originator is the most contested provision because it weakens encryption for all users.
• The 2022 amendment created Grievance Appellate Committees; the 2023 fact-check unit was struck down on Article 19(1)(a) grounds.
• The 2025 and 2026 amendments target synthetically generated information with labelling and compressed deepfake takedown timelines.

• Ladakh lies between Aksai Chin and Gilgit-Baltistan, with both the LAC and LoC on its flanks.
• BADP is a centrally sponsored MHA scheme running since 1986-87, allocated on border length, population and area.
• Its purpose is to give border residents a stake in staying, since depopulated borders are harder to hold.
• The Vibrant Villages Programme (2023) supplements BADP along the northern border specifically.
• Operation Sadbhavana is the Army's flagship civic action programme, with Army Goodwill Schools and the Ladakh Scouts.
• After 2019 Ladakh became a UT without a legislature, losing its prior assembly representation.
• The four-part demand is statehood, Sixth Schedule protection, a public service commission and separate Lok Sabha seats.

• Energy security has four dimensions: availability, accessibility, affordability and acceptability.
• About 85 per cent of crude oil and roughly half of natural gas is imported.
• Coal is domestically secure and environmentally unacceptable, so two dimensions point opposite ways.
• DISCOM losses are the structural weak point: an insolvent discom cannot sign new power purchase agreements.
• The clean transition substitutes oil dependence for concentrated critical mineral dependence.
• Efficiency is the cheapest supply, delivered through PAT trading, star labelling and the 2022 Energy Conservation Amendment.
• The trilemma cannot be solved simultaneously; sequencing with DISCOM solvency as the precondition is the honest answer.

• India has the third-largest startup ecosystem, over 1.5 lakh DPIIT-recognised entities and 100-plus unicorns.
• The Insolvency and Bankruptcy Code 2016 matters because an exit route makes entry rational.
• Over half of recognised startups now come from tier-2 and tier-3 cities.
• Reported direct employment is in the range of 17 to 18 lakh, with larger indirect gig and logistics effects.
• Much Indian startup innovation is business-model adaptation to Indian cost structures rather than deep tech.
• The growth-stage funding gap means scaling companies depend on foreign capital and global rate cycles.
• Reverse flipping is now partially unwinding as Indian listings become attractive.

• Foodgrain output rose from about 51 million tonnes in 1950-51 to well over 330 million tonnes today.
• The FCI and the Agricultural Prices Commission, both 1965, supplied the assured-price machinery the technology needed.
• Green Revolution wheat output roughly tripled within a decade in Punjab, Haryana and western UP.
• Operation Flood made India the largest milk producer; Bt cotton from 2002 transformed fibre.
• The cost was the rice-wheat lock-in, groundwater depletion and skewed nutrient ratios from subsidised urea.
• PM-AASHA aims to extend price assurance beyond cereals, which is the precondition for diversification.
• Diversification is slow because switching crops means switching from a guaranteed buyer to a volatile market.

• Input subsidies cover fertiliser, power, irrigation, credit, seed, machinery and insurance premium.
• MSP is announced for 22 crops plus FRP for sugarcane, but procurement is effective mainly for rice and wheat.
• PM-KISAN is decoupled income support and therefore the least contestable form at the WTO.
• The AoA sorts domestic support into Green, Blue and Amber Boxes, with Amber capped by de minimis.
• The de minimis limit is 10 per cent of value of production for developing countries and 5 per cent for developed.
• The external reference price is frozen at 1986-88 levels and not inflation-adjusted — the central Indian grievance.
• The Bali 2013 peace clause protects public stockholding until a permanent solution, extended indefinitely at Nairobi 2015.

• Mission Drishti was built by GalaxEye, a Bengaluru startup, and launched 3 May 2026 on a SpaceX Falcon 9 from Vandenberg.
• It is the world's first operational OptoSAR satellite, fusing electro-optical and synthetic aperture radar on one platform.
• At about 190 kg it is India's largest privately built satellite.
• Fused resolution is roughly 1.8 metres, with onboard AI inference on NVIDIA Jetson Orin.
• Optical is passive and gives spectral information but fails under cloud and at night; SAR is active and works in all weather but carries no spectral data.
• The first-of-its-kind claim rests on simultaneous same-scene imaging from one platform, removing the temporal and geometric mismatch of ground-based fusion.
• It tests the 2020 space-sector opening and moves Indian spacetech towards proprietary sensing capability.
• Contact with Drishti was lost on 7 July 2026 after a geomagnetic solar storm during LEOP; recovery chances are low, though the technology chain had already been validated in orbit.

• Agentic AI pursues a goal by planning and executing actions, unlike generative AI which produces a single output.
• The loop has five parts: goal, planning, tool use, memory, and reflection with re-planning.
• Tool use is what converts language output into action in the world.
• Multi-agent systems assign specialised roles, improving reliability at the cost of more failure surfaces.
• Compounding error is the central risk: a wrong action changes the world before anyone reviews it.
• Prompt injection through retrieved content can redirect an agent that holds real permissions.
• The regulatory question is permission rather than the model: scoped authority, logging, sandboxing and human approval for irreversible actions.

• India generates roughly 1.7 lakh tonnes of municipal solid waste daily; collection is high but scientific processing is low.
• Mixed waste degrades every downstream option — contaminated compost, low RDF calorific value, devalued recyclables.
• SWM Rules 2016 mandate source segregation, extended producer responsibility and user fees, extending beyond municipal areas.
• Swachh Survekshan turned sanitation into inter-city competition and is the most effective governance instrument in the set.
• Indore achieved segregation by design using partitioned collection vehicles, not by instruction.
• Devguradia hosts Asia's largest bio-CNG plant, fuelling city buses from segregated wet waste.
• Delhi's failure combines fragmented jurisdiction with waste-to-energy capacity built for waste it does not produce.

• The first responder is always the neighbour; most people rescued alive are pulled out before formal response arrives.
• Odisha cyclone deaths fell from roughly 10,000 in 1999 to a handful, through community volunteers and shelter management committees.
• Kerala's 2018 fishermen's rescue fleet used local knowledge no external agency possessed.
• Aapda Mitra deliberately builds capacity that lives in the village rather than arriving in it.
• Sendai Framework Priority 4 on preparedness is explicitly community-anchored.
• Preparedness decays: volunteers lose skills and committees stop meeting within about two years of an event.
• SDRF funds are weighted towards relief rather than preparedness, which structurally underinvests in prevention.

• Separatism operated through a political ecosystem, cross-border support and terror financing sustaining a shutdown economy.
• Article 370 limited Parliament's power to Defence, External Affairs and Communications without state concurrence.
• Article 35A came from the Presidential Order of 1954, not a parliamentary amendment — the core constitutional objection.
• 35A let the state define permanent residents, excluding West Pakistan refugees, Valmikis and Gorkhas for generations.
• On 5 August 2019 a Presidential Order under 370(3) plus the Reorganisation Act created two union territories.
• In Re Article 370 (December 2023) upheld the abrogation and directed restoration of statehood at the earliest.
• Statehood remains unrestored and political alienation is not identical to militancy, which has declined.

• Terrorism is cheap to execute and expensive to sustain, which makes finance the decisive vector.
• High-quality FICN needs industrial capability, pointing to state or state-tolerated production.
• Laundering runs placement, layering and integration; hawala is the dominant Indian channel because it leaves no formal record.
• Terror financing can invert laundering by applying legitimate money to illegitimate ends.
• FATF was established at the 1989 G7 Paris summit; India became a full member in 2010.
• Mutual evaluation assesses technical compliance and effectiveness — most countries fail on the second.
• Grey and black listing work through reputational and correspondent-banking cost rather than formal sanction.
