GS Paper 1 practice questions for UPSC Mains 2026.

Introduction: Place the Indus / Harappan civilisation in the Bronze Age (c. 2600–1900 BCE) and frame the dual claim — urban planning plus craft specialisation.

Body — three dimensions: (1) Hydraulic engineering: Great Bath at Mohenjodaro, Dholavira’s sixteen reservoirs, Lothal dockyard. (2) Town planning: grid streets, citadel–lower town division, covered drains, standardised baked bricks (1:2:4 ratio). (3) Craft and trade economy: shell from Nageshwar, carnelian beads from Chanhudaro, weights in 16-ratios, Meluhha seals at Mesopotamian sites.

Conclusion: The Harappan achievement was an integrated urban system; recent excavations at Rakhigarhi and Sinauli are extending, not overturning, this picture.

Introduction: The Dandi March (12 March to 6 April 1930) launched the Civil Disobedience Movement by walking 240 miles from Sabarmati Ashram to the Dandi sea coast in Gujarat.

Body — three dimensions: (1) Symbolic: salt as universal commodity, breaking a tax monopoly that fell hardest on the poorest — inverting Lord Salisbury’s claim that salt was not a political issue. (2) Strategic: 78 chosen marchers, daily speaking halts, nation-wide replication on the West and East coasts — Sarojini Naidu at Dharasana, C. Rajagopalachari’s Vedaranyam march. (3) International: world press coverage by United Press’ Webb Miller, the Salt March as the moment Indian nationalism became a global news story; led to the Gandhi-Irwin Pact, 5 March 1931 and Gandhi’s Second Round Table Conference visit.

Conclusion: Dandi turned an obscure tax into the most legible image of colonial injustice and made the Congress a global political actor.

Introduction: PLFS 2023-24 reports FLFPR at 41.7%, an 18-point rise in six years; the headline conceals a quality problem.

Body — weigh evidence: (1) Composition: most of the rise sits in unpaid family labour and self-employment in agriculture; salaried regular wage share for women fell to 15.9%. (2) Care burden: NSO Time Use Survey 2024 — women do 289 minutes a day of unpaid domestic work, men 88 minutes (3.3x gap). (3) Policy: Maternity Benefit Amendment 2017, Anganwadi crches under Mission Saksham Anganwadi, Code on Wages 2019, Lakhpati Didi scheme; missing pieces — universal childcare, paid eldercare, social security for gig and self-employed women.

Conclusion: Diane Elson’s ‘recognise, reduce, redistribute’ frame for care work is the missing third pillar; without it, FLFPR rises will keep being counted, not paid.

Introduction: India’s urban share, last measured at 31.16% in Census 2011, is projected by the World Bank’s 2025 report to reach about 951 million urban Indians by 2050.

Body — three dimensions: (1) Migration: 45.36 crore migrants in Census 2011, with rural-to-urban moves driving city growth. PRS data shows over 80% of urban informal workers are migrants. (2) Housing: National Buildings Organisation puts the urban housing shortage at 1.88 crore in 2012 with 95% in EWS and LIG; PMAY-Urban 2.0 (September 2024) sanctioned around 3.53 lakh houses by mid-2025. (3) Governance: 74th Constitutional Amendment 1992 devolved 18 functions to ULBs but state finance commissions remain weak; municipal own revenue is 1% of GDP against the global 7%.

Conclusion: The Isher Judge Ahluwalia HPEC 2011 report’s estimate of ₹39 lakh crore in urban investment over 20 years is still the benchmark; without fiscal devolution to ULBs the dual city will harden.

Introduction: Place the Rigvedic period c. 1500–1000 BCE in the Sapta Sindhu region. Pastoralism dominates the literary surface (gau-dhana, cattle-raid hymns) but archaeology and stray hymns reveal a working agrarian base.

Body — three dimensions: (1) Irrigation and field practice: avata (well), kulya (canal), khanitra (digging tool) in the Rigveda; ploughing references in book IV; barley (yava) as principal crop. (2) Kshetra and ritual: the kshetra-pati hymn (RV IV.57) personifies the field; Atharvaveda's kshetra-patni elevates the 'mistress of the field' as ritual presence; agricultural rites bind the household economy. (3) Continuity into Later Vedic: shift to Doab, iron axes (krishna ayas), expansion into Painted Grey Ware villages — agriculture moves from supplementary to principal. R.S. Sharma's 'Material Culture and Social Formations' anchors this transition.

Conclusion: The pastoral idiom of the Rigveda masks an emerging agrarian order whose deepening through the Later Vedic period laid the base for the second urbanisation.

Introduction: The Gupta age (c. 319–550 CE) under Chandragupta I, Samudragupta, Chandragupta II and Skandagupta is conventionally framed as a classical golden age, a label that deserves disaggregation.

Body — three dimensions: (1) Cultural synthesis: Sanskrit literature peaks with Kalidasa's Abhijnanashakuntalam and Meghaduta, Vishakhadatta's Mudrarakshasa; Aryabhatiya (499 CE) defines astronomy and mathematics; Nalanda emerges as a mahavihara; classical sculpture at Sarnath, Deogarh, Udayagiri caves; decimal system formalised. (2) Political reach: Samudragupta's Allahabad pillar lists conquests but most southern kings remain tributary, not annexed; Hun invasions weaken Skandagupta; empire collapses by mid-6th century. (3) Limits and critique: D.N. Jha and R.S. Sharma point to early feudalism — land grants to Brahmanas and temples, decline of urban-monetary economy, hardening of varna and patriarchy as recorded in Smritis.

Conclusion: The Gupta age is golden in art, science and Sanskritic culture; politically it is a north-Indian classical revival whose social undercurrents preview medieval Indian feudalism.

Introduction: Between 1793 and 1833 the East India Company experimented with three revenue regimes that together covered most of British India and shaped agrarian society into the 20th century.

Body — three dimensions: (1) Permanent Settlement (1793, Bengal, Bihar, Orissa, parts of Madras): Cornwallis fixed land revenue forever with zamindars as proprietors; created absentee landlordism, sub-infeudation, indebtedness; the Sunset Law dispossessed older zamindars. (2) Ryotwari (1820, Madras and Bombay): Thomas Munro and Captain Read settled directly with the cultivating ryot, revenue revised every 30 years, no intermediary — but revenue often set at 45–55% of gross produce, leading to chronic indebtedness and the Deccan Riots of 1875. (3) Mahalwari (1822, North-Western Provinces and Punjab): Holt Mackenzie and R.M. Bird settled with the village (mahal) treated as a corporate body, revenue collected through lambardars; revision every 20–30 years. (4) Common effect: cash revenue regardless of harvest, commercialisation of agriculture (cotton, indigo, opium), rise of moneylender, decline of village artisans — the Bengal famine of 1770 and Madras famine of 1876–78 expose the system's brittleness.

Conclusion: Bipan Chandra reads the three settlements as a single colonial project of revenue maximisation with regional variations; their structures echo into post-1947 land reform debates.

Introduction: Between 1965 and 1990 the Indian state turned a food-deficit, milk-importing economy into a wheat-rice surplus producer and the world's largest milk producer through two state-led technological revolutions.

Body — three dimensions: (1) Green Revolution: launched after the 1965–66 drought and PL-480 dependence; Norman Borlaug's Mexican wheat varieties (Lerma Rojo, Sonora 64) and IRRI's IR-8 rice introduced by M.S. Swaminathan; package programme of HYV seeds, chemical fertilisers, assured irrigation, MSP and FCI procurement after 1965; output of foodgrains rose from 74 million tonnes in 1966-67 to 211 million tonnes by 2001-02. (2) White Revolution: Operation Flood launched 13 January 1970 under Verghese Kurien; Anand pattern co-operative federated as Gujarat Co-operative Milk Marketing Federation (Amul); India became the world's largest milk producer in 1998. (3) Continuity and consequences: both used cooperative-state hybrid institutions and price support; Green Revolution concentrated in Punjab, Haryana, western UP — by-passed eastern India, dryland regions; led to groundwater depletion (CGWB data — 78% blocks in Punjab over-exploited), soil salinity, agrarian distress; White Revolution diffused widely but caused buffalo monoculture and bovine population pressure.

Conclusion: Both revolutions show that scale was achieved by state-cooperative scaffolding; sustaining them now requires correcting regional and ecological imbalances.

Introduction: The Indian subcontinent is built from three structural blocks — the active Himalayan thrust belt, the stable Peninsular shield (the Indian craton with Deccan Trap cover), and the Indo-Gangetic foredeep. Each has a distinct seismic signature.

Body — three dimensions: (1) Tectonic causes: ongoing collision of the Indian Plate moving north at 5 cm/year against the Eurasian Plate generates the Himalayan thrust; intra-plate stresses in the peninsula along the Narmada-Son lineament produced Latur (1993, M 6.4) and Koyna (1967, M 6.5). (2) Bureau of Indian Standards seismic zoning: Zone V (Kashmir, NE, parts of Gujarat, A&N) — very high risk; Zone IV (Delhi NCR, Mumbai metro, parts of UP, Bihar); Zone III (Chennai, Bengaluru), Zone II — low risk. Around 59% of India's land falls in Zone III or higher. (3) Policy gap: NDMA Earthquake Guidelines 2007 require structural compliance with IS 1893; municipal enforcement weak; National Building Code 2016 not adopted by all states; retrofitting limited; Kashmir 2005, Sikkim 2011, Doda 2013, Manipur 2016 illustrate continuing exposure. NDRF and INSAT-3DS provide post-event response.

Conclusion: The shift India needs is from response to risk-informed urban planning along the Himalayan front and in Zone IV megacities.

Introduction: India holds the world's fifth-largest iron ore reserves (over 5.5 billion tonnes per IBM, 2023), is the second-largest crude steel producer (140 million tonnes, 2023), and is targeting 300 million tonnes by 2030 under the National Steel Policy 2017.

Body — three dimensions: (1) Ore geography: 80% hematite reserves in Odisha (Joda-Barbil, Keonjhar), Jharkhand (Singhbhum), Chhattisgarh (Bailadila), Karnataka (Sandur, Hospet); magnetite in Karnataka (Kudremukh) and Tamil Nadu (Salem); siderite minor. (2) Steel plant location: weight-loss principle — older plants (TISCO Jamshedpur 1907, Bhilai 1955, Rourkela 1959, Durgapur 1959, Bokaro 1965) located on Damodar-Subarnarekha coal-iron axis. Newer plants (Vijayanagar JSW, Hospet Karnataka; ArcelorMittal Hazira; AMNS Paradip) on coast-orientation for imported coking coal and export. (3) Policy and industrial corridors: National Steel Policy 2017; PLI for specialty steel 2021; iron ore export restrictions; Vizag-Chennai Industrial Corridor and East Coast Economic Corridor align with new steel geography; railway corridors (DFC East-West) carry iron ore to ports. Conflict: Bailadila in Bastar — Maoist insurgency overlaps with mineral belt.

Conclusion: India's steel future requires integrating mineral logistics, port-led growth (Sagarmala) and conflict-affected mining areas into one industrial policy frame.

Introduction: Sagarmala was approved by the Union Cabinet on 25 March 2015, drawing on the National Perspective Plan 2016, with the four-fold objective of port modernisation, port connectivity, port-led industrialisation, and coastal community development. Sagarmala 2.0 was launched in 2024.

Body — three dimensions: (1) Components: 12 major ports + over 200 non-major ports; six new mega-ports including Vadhavan (Maharashtra, foundation August 2024), Galathea Bay (Great Nicobar), Vizhinjam (Kerala, commissioned 2024) as India's first deep-water transshipment terminal; coastal economic zones; multi-modal logistics parks; Roll-on Roll-off (Ro-Ro) ferries. (2) Progress: 839 projects worth Rs 5.79 lakh crore identified; over 240 projects completed by 2024; coastal cargo doubled 2014–24; Jawaharlal Nehru Port Authority and Mumbai Port pursuing capacity expansion. (3) Concerns and gaps: environmental clearances at Vadhavan and Vizhinjam contested under CRZ; Great Nicobar Holistic Development overlaps Sundaland biodiversity hotspot; coastal fisher displacement (Vizhinjam protests 2022); concentration of investment in west coast; East Coast Economic Corridor implementation slower; dredging and silting in major ports.

Conclusion: Sagarmala's logic — replacing land-based with coast-based logistics — is sound but its execution must reconcile port economics with CRZ, fisher livelihoods and biodiversity.

Introduction: Define communalism as the political mobilisation of religion, distinct from religious diversity. Bipan Chandra's three-stage formulation — communal consciousness, liberal communalism, extreme communalism.

Body — three dimensions: (1) Colonial construction — separate electorates under the Indian Councils Act, 1909; the two-nation theory; partition violence of 1947 killing an estimated 0.2–2 million. (2) Post-1947 incidents — Ahmedabad 1969, Bhiwandi 1970, Sikh massacre 1984, Mumbai 1992-93, Gujarat 2002, Muzaffarnagar 2013, Delhi February 2020 (53 dead per Delhi Police). (3) Drivers — fake news on social media, urban segregation, ‘love jihad’ and conversion laws in Uttar Pradesh and Madhya Pradesh.

Conclusion: Constitutional secularism (Articles 25–28, S.R. Bommai 1994 judgment), the Sachar Committee (2006) and the National Foundation for Communal Harmony are the institutional response; political will is the missing input.

Introduction: The Multidimensional Poverty Index (MPI), developed by Sabina Alkire and James Foster at OPHI (2010), measures poverty as overlapping deprivation in health, education and living standards.

Body — three dimensions: (1) Method — 12 indicators across 3 dimensions; a household is multidimensionally poor if deprived in at least one-third weighted indicators; NITI Aayog's National MPI uses NFHS data. (2) Progress — national MPI head-count ratio fell from 29.17% (2013-14) to 11.28% (2022-23); 24.82 crore lifted out (NITI Aayog Discussion Paper, January 2024). (3) Persistence — Bihar 33.76%, Jharkhand 28.81%, Meghalaya 27.79% still poor; nutrition (33% deprivation) and maternal health (22%) the slowest indicators.

Conclusion: The MPI moves with PMAY, Jal Jeevan, Ujjwala, Saubhagya — but anaemia, nutrition and antenatal care need targeted convergence, especially in EAG states.

Introduction: FLFPR (15+) jumped to 41.7% by PLFS 2023-24; yet the Time Use Survey 2019 shows women spend 299 minutes/day on unpaid domestic services vs 97 for men — a 3:1 gap.

Body — three dimensions: (1) Quality — most of the rise is in unpaid family-farm or own-account self-employment, not waged jobs; agricultural feminisation. (2) Care burden — TUS-2019: women 134 min/day on care of children/elderly/sick vs 76 for men; 53.7% of e-Shram registrants female. (3) Policy — Mission Shakti's Sambal (safety) + Samarthya (empowerment) pillars; PMMVY ₹5,000 maternity benefit; creche provisions under the Code on Social Security; Anganwadi as a care infrastructure.

Conclusion: Recognising, reducing, redistributing unpaid care (Diane Elson's 3R framework) is the missing leg — invest in childcare, eldercare and time-saving infrastructure (water taps, LPG) to convert FLFPR rise into real economic agency.

Introduction: NFHS-5 (2019-21) — stunting 35.5%, wasting 19.3%, underweight 32.1%, child anaemia 67.1%. India runs the world's largest child-nutrition programme yet one in three under-fives is stunted.

Body — three dimensions: (1) The 20-80 split — Bhutta (Lancet 2013): direct nutrition interventions cut stunting only ~20%, the rest rides on WASH, maternal health, poverty. (2) Maternal-cycle problem — low birth weight 27.4%, women's anaemia 57%; about half of growth failure happens in the womb. (3) Scheme architecture — POSHAN 2.0 reaches ~10 crore beneficiaries across 14 lakh Anganwadis, ₹21,960 crore in 2025-26; Poshan Tracker app; Anemia Mukt Bharat.

Conclusion: Converge Jal Shakti (sanitation, water), Health (anaemia, antenatal care), Women and Child Development (POSHAN) and Education in the same district — nutrition is a horizontal problem trapped in a vertical bureaucracy.

Introduction: The Hashim Committee (2012) estimated urban housing shortage at 1.88 crore units, of which ~96% was in EWS/LIG. PMAY-U (launched 25 June 2015) has sanctioned about 1.18 crore homes by 2024.

Body — three dimensions: (1) Supply gaps — PMAY-U four verticals (ISSR, AHP, BLC, CLSS); PMAY-U 2.0 (2024) targets 1 crore more; affordable rental housing complexes for migrants. (2) Demand side — urban informality, in-situ slum upgrading vs eviction; 65 million slum residents (Census 2011). (3) Employment side — case for an Urban Employment Guarantee Scheme: Kerala's Ayyankali Scheme, Himachal's MGNREGS-style urban programmes; need is highest among construction-dependent workers post-pandemic.

Conclusion: Bundle PMAY-U 2.0 with rental housing for migrants and an UEGS as a counter-cyclical floor; otherwise PMAY units stand empty while migrants live in slums.

Introduction: Indian secularism = principled distance (Rajeev Bhargava), allowing state engagement with religion for reform while maintaining equal respect. 42nd Amendment (1976) inserted ‘secular’ in the Preamble.

Body — three dimensions: (1) Constitutional fabric — Articles 25–28 (freedom of religion), 29-30 (minority rights), 44 (UCC directive); S.R. Bommai (1994) — secularism as basic structure. (2) State engagement — Hindu Code Bill 1955-56, Places of Worship Act 1991, Triple Talaq verdict (Shayara Bano, 2017) and law 2019, Sabarimala (2018). (3) Tensions — Sachar Committee 2006 (Muslim deprivation index), CAA 2019 debate, anti-conversion laws in 9 states.

Conclusion: The model permits intervention for equality while protecting religious freedom; the test is even-handed application, not retreat to either French or American template.

Introduction: World crude-steel output crossed 1,892 million tonnes in 2023 (worldsteel). Top five: China (1,019 MT), India (140 MT), Japan (87 MT), USA (81 MT), Russia (76 MT).

Body — three dimensions: (1) Raw-material orientation (Weber's theory) — coking coal, iron ore, limestone bulky, high weight-loss; Ruhr (Germany), Donbas (Ukraine), Pittsburgh historically; India's Jamshedpur near Jharia coal and Singhbhum iron. (2) Market orientation — Japan (Yawata, Kawasaki) built on imported ore (Australia) and coking coal (Indonesia), located on coastal sites near consumers. (3) Energy and policy — China's Anshan-Wuhan-Baotou belt on Datong coalfield; India's Bhilai and Rourkela located on Bailadila and Barsua ore via national policy.

Conclusion: Modern steel locations are pulled by ports more than coalfields — Japan's coastal model and India's emerging coastal capacity (Paradip, Hazira) confirm the shift.

Introduction: India's 2011 population was 1.21 billion; UN World Population Prospects 2024 puts 2024 estimate at 1.45 billion. National density 382/km² (Census 2011); huge regional disparity.

Body — three dimensions: (1) Density — Bihar 1,106/km², West Bengal 1,028, Kerala 859 vs Arunachal Pradesh 17/km², Mizoram 52, Sikkim 86; six states (UP, Maharashtra, Bihar, WB, MP, TN) hold ~50% of population. (2) Growth — Census 2011 decadal growth 17.7% (down from 21.5% in 2001); EAG states above 20%, southern states below 16%. (3) Migration — Census 2011 recorded 45.6 crore internal migrants (37.6% of population); Bihar-UP source corridor to Delhi-Mumbai-Punjab; PMGKY 2020 pandemic exposed migrant precarity.

Conclusion: Geography determines who is dense, who is sparse, and who moves — the 2027 Census will be the first to map this in 16 years.

Introduction: Groundwater meets 62% irrigation needs and 85% rural drinking water; India is the world's largest groundwater user (~245 BCM annually, ~25% of global use).

Body — three dimensions: (1) Spatial stress — CGWB Dynamic Assessment 2024: of 6,746 blocks/units assessed, 751 over-exploited (>100% extraction) and 206 critical; concentrated in Punjab, Haryana, Rajasthan, western UP, Tamil Nadu's Cauvery delta. (2) Drivers — free/subsidised power for tube wells, MSP-led paddy-wheat in northwest, sugarcane in Maharashtra; recharge falling as monsoon variability rises. (3) Policy — Atal Bhujal Yojana (2019, ₹6,000 crore) in seven states; Jal Shakti Abhiyan ‘Catch the Rain’; PMKSY-Per Drop More Crop micro-irrigation push.

Conclusion: Switch to participatory groundwater management at panchayat level, decouple electricity subsidy from extraction, and align crop choice with aquifer recharge.
