TNPSC Group 2 Mains 2025 Question Paper with Answers – GS Paper II

• Intro: The Palayakarar (Poligar) revolts (1799 and 1800–01) in the Tamil country were among the earliest armed resistances to Company rule; the 1800–01 phase is called the 'South Indian Rebellion'.
• Causes: Carnatic Treaty of 1792 gave the East India Company the right to collect tribute (kist) from the palayams; harsh revenue demands and insults (Jackson–Kattabomman meeting at Ramanathapuram, 1798) hurt the palayakarars' sovereignty and honour.
• Causes (contd.): Company interference in the palayakarars' policing and judicial rights; loss of traditional status; earlier resistance by Puli Thevar (1750s) set a precedent.
• First revolt (1799): Veerapandiya Kattabomman of Panchalankurichi resisted; fort captured by Major Bannerman; Kattabomman hanged at Kayathar on 16 October 1799.
• Second revolt (1800–01): a confederacy led by the Marudhu brothers of Sivagangai with Oomaithurai and Dheeran Chinnamalai's support; Tiruchirappalli Proclamation (June 1801) called all people to unite; the Marudhu brothers were hanged at Tiruppathur (Sivagangai) in October 1801.
• Results: Carnatic Treaty of 1801 brought the Tamil region under direct British control; the palayakkarar system was abolished, forts demolished, people disarmed; the zamindari (Permanent Settlement) system was introduced from 1802.
• Conclusion: Though crushed, the revolts became the first chapter of Tamil Nadu's freedom struggle and a lasting source of inspiration (e.g. Vellore Revolt 1806).

• Intro: Maternity cash benefits are conditional cash transfers meant to protect the health of mother and newborn; the National Food Security Act, 2013 (Sec. 4) entitles pregnant women and lactating mothers to maternity benefit of not less than Rs 6,000.
• Schemes: Pradhan Mantri Matru Vandana Yojana (2017; Rs 5,000 for the first child, and under Mission Shakti an additional benefit for a second child if a girl); Janani Suraksha Yojana (2005) for institutional delivery; Tamil Nadu's Dr. Muthulakshmi Reddy Maternity Benefit Scheme (Rs 18,000 including nutrition kits).
• Wage-loss compensation: women in the unorganised sector lose income around childbirth; cash after delivery allows rest and recovery instead of an early return to work.
• Nutrition and breastfeeding: money supports the mother's diet and exclusive breastfeeding for six months, reducing maternal anaemia and low birth weight.
• Conditionality as a nudge: instalments linked to institutional delivery, birth registration and child immunisation improve health-seeking behaviour; Direct Benefit Transfer reduces leakage.
• Outcome: institutional deliveries and falling MMR/IMR – Tamil Nadu's MMR is far below the national average (SRS).
• Conclusion: Post-delivery cash is an investment in the first 1,000 days of life; timely payment and wider coverage of informal workers will make it more effective.

• Intro: Census 2011 – 31.16% of India's population (about 377 million) was urban; Tamil Nadu (48.45%) is among the most urbanised large States.
• Census towns and 'hidden' urbanisation: census towns rose from 1,362 (2001) to 3,894 (2011) – villages turning urban without municipal status.
• Metropolitan concentration and peri-urban sprawl: 53 million-plus cities (2011); growth along corridors and satellite towns around Chennai, Bengaluru, Delhi NCR.
• Rise of Tier-2/Tier-3 cities as service and manufacturing hubs (e.g. Coimbatore, Tiruppur, Madurai in TN).
• Policy-led urbanisation: Smart Cities Mission and AMRUT (2015), PMAY-Urban, metro rail and transit-oriented development, Swachh Bharat (Urban).
• Challenges: slums (about 65 million slum dwellers, Census 2011), informal jobs, urban flooding, heat islands, traffic and weak finances of urban local bodies (74th Amendment only partly implemented).
• Conclusion: India must move from unplanned to planned, climate-resilient and inclusive urbanisation.

• The 2023 Nobel Prize in Chemistry was awarded 'for the discovery and synthesis of quantum dots' to:
• Moungi G. Bawendi (MIT, USA) – developed high-quality chemical synthesis of quantum dots (1993).
• Louis E. Brus (Columbia University, USA) – showed size-dependent quantum effects in colloidal nanoparticles in solution (1983).
• Alexei I. Ekimov (Nanocrystals Technology Inc., USA; earlier in the USSR) – first created size-dependent quantum effects in coloured glass (early 1980s).
• Key idea: quantum dots are semiconductor nanocrystals (2–10 nm) whose colour/optical properties depend on their size.

Diagram / table: Simple figure: smaller dot → blue light, larger dot → red light (size vs colour).

• Displays: QLED television and monitor screens – pure, bright colours with lower power use.
• Lighting: quantum-dot LEDs that give warm, energy-efficient white light.
• Medicine: fluorescent labels for bio-imaging – tracing tumour tissue to guide surgeons, and cell/molecule tracking.
• Solar energy: quantum-dot solar cells and photodetectors that can absorb a wider range of sunlight.
• Quantum technologies and sensors: single-photon sources for quantum communication/encryption; chemical and bio-sensors; photocatalysis.

Diagram / table: Table: Field | Application | Property used (size-tuned colour, bright fluorescence, light absorption).

• Intro: High Courts (Articles 214–231) are the apex courts of the States with writ jurisdiction under Article 226 and superintendence over subordinate courts (Article 227).
• Pendency: lakhs of cases are pending in High Courts (National Judicial Data Grid) – delays defeat 'justice delayed is justice denied'.
• Vacancies and appointment delays: a large share of sanctioned judge posts remain vacant; delays between collegium recommendation and government notification; Memorandum of Procedure not finalised.
• Transparency and accountability: opaque collegium selection; no effective mechanism short of removal (Article 217 read with Article 124(4)); low diversity (few women and under-represented groups).
• Access issues: proceedings in English (Article 348) – demand for Tamil in the Madras High Court; distance for litigants (Madurai Bench since 2004 eased this for south TN); high costs and frequent adjournments.
• Infrastructure and administration: shortage of staff and courtrooms; slow digitisation in some courts; long vacations.
• Way forward: time-bound appointments, e-Courts Phase III, case management and AI tools, more benches, ADR/Lok Adalats, regional-language judgments. Conclusion: reforms must strengthen efficiency without diluting judicial independence.

• Background: Dhar Commission (1948) and JVP Committee (1949) were cautious; after Potti Sriramulu's fast-unto-death, Andhra State was formed (1953); Fazl Ali States Reorganisation Commission (1953–55) led to the States Reorganisation Act, 1956 (14 States, 6 Union Territories). Madras State was renamed Tamil Nadu in 1969.
• Merit – administrative efficiency: administration, courts and education in the people's language bring government closer to citizens.
• Merit – democratic participation and cultural growth: regional languages, literature and identity flourished; Tamil gained wider official use.
• Merit – national unity: accommodating linguistic aspirations defused agitations and strengthened federalism ('unity in diversity').
• Demerit – sub-regionalism and new demands for division (e.g. Telangana, 2014); 'sons of the soil' attitudes.
• Demerit – border and river-water disputes (e.g. Belagavi; Cauvery) and problems of linguistic minorities (safeguards: Articles 350A, 350B).
• Conclusion: On balance linguistic reorganisation strengthened Indian unity; cooperative federalism and protection of minorities address its side-effects.

• Intro: Regional (State) parties represent region-specific language, culture and development interests; Tamil Nadu has been ruled by Dravidian parties continuously since 1967.
• Coalition politics: from 1989 to 2014 no single party won a Lok Sabha majority; in 2024 the ruling party (240 seats) again depended on regional allies – regional parties became kingmakers.
• Federal assertion: they champion State autonomy and fiscal federalism (Rajamannar Committee 1969 by TN; Sarkaria 1983 and Punchhi 2007 Commissions), Governor's role, GST compensation and Finance Commission devolution.
• Identity and welfare politics: language, social justice and welfare schemes connect directly with voters (TN's reservation and welfare model).
• Policy influence: shaping national debates on issues like NEET, delimitation, Hindi imposition and Centre–State relations.
• Concerns: dynastic politics, freebie competition, narrow regional focus and coalition instability.
• Conclusion: Regional parties deepen democracy and federalism when they balance regional interests with national goals.

• Intro: Ecological balance is the dynamic equilibrium among species and their environment maintained through food chains and nutrient cycles; IPBES (2019) warned that about one million species face extinction.
• Food-web collapse: loss of a species breaks food chains – prey populations explode or predators starve (trophic cascade).
• Keystone species: removal of tigers, elephants or sea otters changes the entire ecosystem; reintroduction of wolves in Yellowstone (1995) showed the reverse effect.
• Loss of ecosystem services: decline of pollinators (bees) hits crop yields; loss of seed dispersers affects forest regeneration.
• Indian example: collapse of vulture populations (due to the veterinary drug diclofenac) left carcasses uncleared, increased feral dogs and rabies risk.
• Nutrient cycling and disease: decomposers and predators keep pests and pathogens in check; their loss favours invasive species and disease outbreaks.
• Conclusion: Protecting biodiversity – protected areas, Biological Diversity Act 2002, Project Tiger/Elephant, Nilgiri Tahr project in TN – is essential to keep ecosystems stable.

• Definition: Balance of Payments is a systematic record of all economic transactions between residents of a country and the rest of the world in a given period (IMF BPM6 framework; compiled in India by the RBI).
• Current account – (a) merchandise trade (exports and imports of goods); (b) invisibles: services (IT/software, travel, transport), primary income (interest, dividends, wages) and secondary income (remittances, grants).
• Capital (and financial) account – foreign direct investment, foreign portfolio investment, external commercial borrowings, external assistance, NRI deposits and other capital flows.
• Errors and omissions – a balancing item for statistical discrepancies.
• Change in foreign exchange reserves – the overall surplus/deficit is settled by a change in RBI's reserves (and IMF transactions).
• India's pattern: persistent merchandise trade deficit, offset largely by a services surplus and remittances (India is the world's largest recipient of remittances); 1991 BoP crisis led to reforms.
• Conclusion: The BoP always balances in accounting terms; a sustainable current-account deficit financed by stable FDI is the policy goal.

• Intro: Adichanallur, on the banks of the Thamirabarani in Thoothukudi district, is one of the largest Iron Age urn-burial sites of South India.
• Excavation history: first excavated by the German Dr. Andreas Fedor Jagor (1876); extensive excavation by Alexander Rea of the Archaeological Survey (from 1899); ASI re-excavation in 2004–05; renewed work in recent years.
• Nature of burials: human remains placed in large terracotta urns (burial urns) buried in pits cut into the rock/gravel; some urns contained complete skeletons, others secondary burials.
• Grave goods: iron weapons and tools, bronze objects, gold diadems (mouthpieces), black-and-red ware pottery, beads, husk and grains – showing metallurgy, agriculture and belief in an after-life.
• Significance: evidence of an advanced Iron Age culture on the Thamirabarani; links with the habitation evidence nearby and with Sangam-age culture (cf. Sivakalai, Keezhadi).
• Recognition: declared one of five 'iconic archaeological sites' in the Union Budget 2020–21; foundation stone for an in-situ site museum laid in August 2023.
• Conclusion: Adichanallur pushes back the antiquity of Tamil civilisation and is central to the study of Tamil heritage.

• Intro: Thiruvalluvar devotes a full chapter, 'Naduvunilaimai' (Impartiality, Chapter 12, Kurals 111–120, Arathuppal – Illaraviyal), to fairness in thought, word and deed.
• Definition: Impartiality is to act justly towards all – friend, foe and stranger alike (Kural 111: 'தகுதி எனவொன்று நன்றே பகுதியால் பாற்பட்டு ஒழுகப் பெறின்').
• Its fruit: the wealth of the just man does not perish and passes on as security to his descendants (Kural 112).
• Reject unjust gain: give up at once any gain that comes by abandoning fairness, even if it seems good (Kural 113).
• Image of the balance: like a balance that weighs evenly, the wise do not lean to one side (Kural 118: 'சமன்செய்து சீர்தூக்குங் கோல்போல் அமைந்தொருபால் கோடாமை சான்றோர்க் கணி').
• Self-check and application: a person who swerves from fairness should know he is ruining himself (Kural 116); even traders should guard others' interests as their own (Kural 120).
• Conclusion: Valluvar's ideal of impartiality is relevant to judges, administrators and public servants today – the core of good governance and integrity.

• Intro: Kalithogai is one of the Ettuthogai (Eight Anthologies) of Sangam literature; its Mullaikkali section (17 poems) was composed by Chozhan Nalluruthiran and describes the life of the Ayar (herding community), including 'Eru Thazhuvuthal' (bull-embracing/taming).
• The event: fierce bulls with sharpened horns were released into an enclosure (thozhu); young Ayar men leapt to embrace and hold the bulls' humps and horns.
• Valour and marriage: a girl of the Ayar community would marry only the youth who tamed her family's bull – 'கொல்லேற்றுக் கோடஞ்சுவானை மறுமையும் புல்லாளே ஆய மகள்' (Kalithogai 103): she will not embrace, even in the next birth, one who fears the horns of the killer bull.
• Vivid descriptions: bulls of different colours, the sound of drums, dust rising, wounded youths – the arena is compared to a battlefield.
• Social aspects: the whole community gathered to watch and cheer; the event was followed by the 'kuravai' dance and was linked to worship and community festivity.
• Continuity: today's Jallikattu (e.g. Alanganallur, Palamedu, Avaniyapuram) continues this tradition; after the 2017 protests Tamil Nadu amended the Prevention of Cruelty to Animals Act, upheld by the Supreme Court Constitution Bench in 2023.
• Conclusion: Mullaikkali is the oldest literary evidence of Jallikattu as a symbol of Tamil valour and culture.

• Intro: Folk music is the oral, community-based music of the common people, linked to work, seasons, festivals and life-cycle events, passed down through generations.
• Features: simple tunes, local dialect, collective singing, use of indigenous instruments, and themes of nature, love, devotion and social life.
• Regional forms: Baul and Bhatiali (Bengal), Bihu songs (Assam), Lavani (Maharashtra), Pandavani (Chhattisgarh), Manganiyar/Langa songs (Rajasthan), Bhangra/Boliyan (Punjab).
• Tamil Nadu: Thalattu (lullaby), Oppari (lament), Etra paattu and harvest songs (work songs), Kummi and Kolattam songs, Villupattu, Naiyandi melam, Gaana (Chennai).
• Instruments: Parai, Thavil, Urumi, Nadaswaram, Ektara, Dotara, Dhol, Algoza.
• Significance and protection: preserves history and identity, a medium for social messages (freedom movement, awareness campaigns); supported by Sangeet Natak Akademi, Zonal Cultural Centres and Tamil Nadu Iyal Isai Nataka Mandram (Kalaimamani awards).
• Conclusion: Folk music is the living root of Indian music; documentation and support for artists are needed against commercial decline.

• Intro: The Dravidian Movement was a social-justice and self-respect movement in Tamil Nadu against caste hierarchy and for the rights of non-Brahmins, Tamil language and identity.
• Origins: Madras Dravidian Association (1912, C. Natesanar); South Indian Liberal Federation (Justice Party) founded in 1916 by Dr. T. M. Nair and Sir P. Theagaraya Chetty with Natesanar; Non-Brahmin Manifesto (December 1916).
• Justice Party rule (from 1920): Communal G.O.s (1921, 1922) for reservation in government jobs; Hindu Religious Endowments Act; mid-day meal experiment in Madras city; women's franchise (1921).
• Self-Respect Movement (1925) of Periyar E. V. Ramasamy: rationalism, abolition of caste, women's rights, self-respect marriages; journal 'Kudi Arasu'; first anti-Hindi agitation (1937–40).
• Dravidar Kazhagam (1944, Salem conference) and DMK (1949, C. N. Annadurai); anti-Hindi agitation of 1965.
• Political power: DMK government in 1967; Self-Respect Marriages legalised (1967); State renamed Tamil Nadu (1969); AIADMK formed in 1972 by M. G. Ramachandran – Dravidian parties have ruled TN since 1967.
• Conclusion: The movement shaped TN's social-justice model – reservation, welfare schemes and Tamil identity – though issues like caste discrimination remain.

• Intro: Vasco da Gama reached Calicut in 1498 by the Cape route; the Portuguese came for spices, especially pepper, and their power grew out of trade.
• Trading posts to forts: factories at Calicut, Cochin and Cannanore; the first fort at Cochin (1503) – commercial settlements became bases of political power.
• Francisco de Almeida (1505–09): 'Blue Water Policy' – naval supremacy to protect trade; victory at the Battle of Diu (1509) over the Egyptian–Gujarat fleet.
• Afonso de Albuquerque (1509–15): captured Goa from Bijapur (1510), Malacca (1511) and Hormuz (1515) – controlling the key choke-points of Indian Ocean trade; Goa became capital of the 'Estado da India'.
• Cartaz system: Asian ships had to buy Portuguese passes; monopoly over spices and control of the horse trade (Arab/Persian horses supplied to Vijayanagara) brought revenue and political leverage.
• Expansion of settlements for trade: Bassein (1534), Diu (1535), Daman, Hooghly (1579), San Thome (Mylapore) and Nagapattinam on the Coromandel coast.
• Limits and decline: religious intolerance and the Goa Inquisition (1560), corruption, small population, rise of the Dutch and English (Battle of Swally, 1612), Spanish union (1580–1640).
• Conclusion: Trade backed by sea power created the first European maritime empire in India; Goa, Daman and Diu remained Portuguese until 1961.

• Intro: The press was the 'voice of the nation' – it spread political awareness, exposed colonial exploitation and united Indians across regions.
• Early phase: Hicky's Bengal Gazette (1780); Raja Ram Mohan Roy's Sambad Kaumudi and Mirat-ul-Akbar – social reform and press freedom.
• Nationalist papers: The Hindu (1878, co-founded by G. Subramania Iyer) and his Swadesamitran (1882); Amrita Bazar Patrika; Tilak's Kesari and Mahratta; Agarkar and Gokhale's Sudharak – Moderates used the press to criticise drain of wealth and demand reforms.
• Tamil Nadu: Subramania Bharathi's 'India' (1906) and his patriotic writings; V. O. Chidambaram Pillai's Swadeshi campaign was reported widely; Periyar's 'Kudi Arasu' (1925) for social justice.
• Gandhian era: Young India, Navajivan and Harijan carried Satyagraha messages to the masses; Bombay Chronicle and National Herald.
• Repression proves its power: Vernacular Press Act (1878, repealed 1882), Newspapers (Incitement to Offences) Act 1908, Indian Press Act 1910, Press (Emergency Powers) Act 1931; Tilak's sedition trials.
• Limitations: low literacy, urban and elite readership, financial weakness, some communal papers.
• Conclusion: Despite limits, the press built a national public opinion and trained leaders; its legacy is reflected in Article 19(1)(a).

Diagram / table: Table: Newspaper | Founder/Editor | Year | Contribution; plus a column of repressive press laws.

• Intro: Commercialisation meant growing crops for sale in national/international markets rather than for village consumption – driven by Britain's industrial needs, not by Indian farmers' choice.
• Causes: land revenue demanded in cash (Permanent Settlement 1793, Ryotwari – Munro in Madras), railways and Suez Canal (1869) linking ports to world markets, demand for raw materials (cotton, indigo, jute, tea, opium).
• Shift from food to cash crops: indigo, cotton (American Civil War boom 1861–65), jute, sugarcane, groundnut in Madras Presidency – reduced food-grain output and food security.
• Famines and distress: recurring famines (Great Famine 1876–78 hit the Madras Presidency hard); price crashes left peasants indebted.
• Indebtedness and land alienation: moneylenders and traders grabbed land (Deccan Riots 1875); growth of landless labourers and tenancy.
• Exploitation and revolts: forced indigo cultivation – Indigo Revolt (1859–60), Champaran Satyagraha (1917); plantation labour and indentured migration (to Ceylon, Malaya, etc.) from Tamil districts.
• Some positive effects: market integration, a class of rich peasants, spread of new crops; but gains went mostly to traders and the colonial state (drain of wealth).
• Conclusion: Commercialisation without investment in irrigation or technology impoverished Indian agriculture – a legacy addressed after independence by land reforms and the Green Revolution.

Diagram / table: Flowchart: cash revenue + railways + British demand → cash crops → less food grain → famine/indebtedness → land alienation → peasant revolts.

• Intro: SCs (16.6%) and STs (8.6%) of India's population (Census 2011); in Tamil Nadu SCs are 20.01% and STs 1.10%. Constitutional base: Articles 15(4), 16(4), 17, 46, 275(1), 330, 332, 338, 338A, Fifth and Sixth Schedules.
• Legal protection: Protection of Civil Rights Act 1955; SC/ST (Prevention of Atrocities) Act 1989 (amended 2015, 2018); PESA 1996; Forest Rights Act 2006.
• Central education schemes: Post-Matric and Pre-Matric Scholarships, National Overseas Scholarship, Eklavya Model Residential Schools, hostels.
• Central economic and livelihood schemes: PM Anusuchit Jaati Abhyuday Yojana (PM-AJAY), Stand-Up India (bank loans for SC/ST and women entrepreneurs), NSFDC/NSTFDC loans, PM-JANMAN (2023) for Particularly Vulnerable Tribal Groups, Dharti Aaba Janjatiya Gram Utkarsh Abhiyan.
• Tamil Nadu: 69% reservation including 18% SC and 1% ST (Tamil Nadu Act 45 of 1994, placed in the Ninth Schedule by the 76th Amendment, 1994); Adi Dravidar and Tribal Welfare Department hostels and schools; TAHDCO loans and housing; Annal Ambedkar Business Champions Scheme (2023); free education/scholarships; 'Tholkudi' scheme (TN Budget 2024–25, about Rs 1,000 crore) to improve the living standards of tribal communities.
• Analysis – achievements: rising literacy, representation in legislatures and services, entrepreneurship; TN's strong social-justice tradition.
• Analysis – gaps: under-utilisation and diversion of SC/ST sub-plan funds, delays in scholarships, low conviction under the Atrocities Act, manual scavenging persists, landlessness, poor implementation of FRA, data gaps.
• Way forward and conclusion: outcome-based budgeting, timely DBT, special courts, land and skill access, social audit – moving from welfare to empowerment as envisioned by Dr. Ambedkar.

• Formation: the Bhanwari Devi case led to Vishaka v. State of Rajasthan (1997) – the Supreme Court framed the Vishaka Guidelines under Articles 14, 15, 19(1)(g) and 21 and CEDAW; reiterated in Medha Kotwal Lele (2012); Parliament enacted the Sexual Harassment of Women at Workplace (Prevention, Prohibition and Redressal) Act, 2013 (in force from 9 December 2013).
• Feature – wide definitions: sexual harassment includes physical contact, demand for sexual favours, sexually coloured remarks, showing pornography and other unwelcome conduct (Sec. 2(n)); 'workplace' covers public and private sectors, unorganised sector, dwelling places and places visited during employment.
• Feature – Internal Committee (Sec. 4): mandatory for every workplace with 10 or more employees – presided by a senior woman employee, at least half the members women, and one external member from an NGO/expert.
• Feature – Local Committee (Sec. 6): constituted by the District Officer for workplaces with fewer than 10 employees and for domestic and informal workers.
• Feature – procedure: complaint within three months (extendable by three months); conciliation possible but no monetary settlement; inquiry to be completed within 90 days; interim relief; confidentiality; employer's duties; penalty up to Rs 50,000 for non-compliance (higher for repeat); SHe-Box online portal.
• Hurdles: many organisations have not constituted ICs (Supreme Court in Aureliano Fernandes v. State of Goa, 2023, flagged this); weak Local Committees; informal-sector women largely uncovered; fear of retaliation and stigma; IC members lack training and independence; Sec. 14 (malicious complaint) deters complainants; low awareness; unclear coverage of political parties, sportspersons, gig workers.
• Tamil Nadu: Tamil Nadu State Commission for Women and district Local Committees; awareness through the Social Welfare Department.
• Conclusion: Mandatory audits, digital tracking of ICs, training, coverage of gig and informal workers and gender-sensitisation will turn the law into a safe-workplace reality.

• Intro: Article 40 (DPSP) directs the State to organise village panchayats; Gandhiji's 'Gram Swaraj' ideal; in Tamil Nadu, Uthiramerur inscriptions (Chola period) show ancient village self-government (kudavolai system).
• Evolution: Balwant Rai Mehta Committee (1957) – three-tier system, first launched at Nagaur, Rajasthan (2 October 1959); Ashok Mehta (1977), G. V. K. Rao (1985), L. M. Singhvi (1986) committees.
• 73rd Constitutional Amendment Act, 1992 (in force 24 April 1993 – National Panchayati Raj Day): Part IX (Articles 243 to 243-O) and the Eleventh Schedule (29 subjects); Gram Sabha (243A); three tiers; five-year term; reservation for SC/ST and not less than one-third for women; State Election Commission (243K); State Finance Commission (243-I). PESA Act 1996 for Fifth Schedule areas.
• Tamil Nadu: Tamil Nadu Panchayats Act, 1994; three tiers – village panchayats, panchayat unions and district panchayats; 50% reservation for women; Gram Sabha meetings on fixed days (26 January, 1 May, 15 August, 2 October, and later added days such as 22 March and 1 November).
• Achievements: grassroots democracy, women's leadership, local planning (Gram Panchayat Development Plans), implementation of MGNREGS, Jal Jeevan Mission, sanitation.
• Problems: inadequate devolution of funds, functions and functionaries ('3Fs'); dependence on grants; weak own revenue; bureaucratic control; proxy representation ('sarpanch-pati'); irregular elections in some States; weak Gram Sabhas; capacity gaps.
• Measures: activity mapping and real devolution of 3Fs; timely State Finance Commissions and Finance Commission grants; property-tax and own-source revenue; e-Gram Swaraj, Meri Panchayat, SVAMITVA; training under Rashtriya Gram Swaraj Abhiyan; strict action against proxy leaders; social audit and strong Gram Sabhas.
• Conclusion: Empowered panchayats are the foundation of 'democratic decentralisation' and inclusive rural development.

• Intro: Blockchain is a decentralised, distributed digital ledger in which records (blocks) are cryptographically linked, making them transparent, tamper-resistant and verifiable without a central authority; Bitcoin (2009) was only its first use.
• Smart contracts: self-executing code (e.g. on Ethereum) automates insurance claims, trade finance and payments when conditions are met.
• Supply chains and agriculture: farm-to-fork traceability of food, drugs and seeds; checks counterfeits; helps farmers get fair prices and organic certification.
• Governance: land records and property registration, digital certificates (education, caste/income), e-procurement, transparent subsidy delivery; MeitY's National Strategy on Blockchain (2021); Tamil Nadu Blockchain Policy (2020) and the State's blockchain backbone 'Nambikkai Inaiyam'.
• Health and identity: secure patient records shared with consent; self-sovereign digital identity; tracking of vaccines and organ donation.
• Others: tamper-proof voting trials, intellectual-property and copyright registration, energy (peer-to-peer power trading), banking KYC and cross-border trade documentation, NFTs.
• Challenges: scalability and speed, energy use (proof-of-work), privacy versus transparency, interoperability, legal recognition and skills gap.
• Conclusion: Used wisely, blockchain can build 'trust by design' into governance and the economy, far beyond cryptocurrencies.

• Definition: Artificial (synthetic) seeds are somatic embryos, shoot buds or other meristematic propagules produced by plant tissue culture and encapsulated in a protective gel coat so that they can be handled, stored and sown like natural seeds; the idea was proposed by Toshio Murashige (1977).
• Types: hydrated (encapsulated in hydrogel such as sodium alginate) and desiccated (coated with polyoxyethylene and dried) synthetic seeds.
• Step 1 – Selection of an elite mother plant and explant (leaf, shoot tip, embryo); surface sterilisation.
• Step 2 – Callus/embryogenic culture on a nutrient medium with plant growth regulators, followed by induction of somatic embryogenesis (or shoot-bud formation).
• Step 3 – Maturation and synchronisation of somatic embryos (uniform size and stage).
• Step 4 – Encapsulation: mixing embryos in sodium alginate solution (about 2–4%) and dropping into calcium chloride solution, forming calcium-alginate beads (artificial endosperm with nutrients, fungicides may be added).
• Step 5 – Storage (low temperature) and conversion/germination in vitro or in soil, followed by hardening.
• Importance in forestry: mass clonal propagation of elite trees (teak, eucalyptus, sandalwood, bamboo) for plantations; conservation of rare, endangered and endemic species; propagation of species with recalcitrant/short-viability seeds or long seed cycles; easy germplasm storage and exchange (with cryopreservation); disease-free, genetically uniform planting stock; reduces cost and time of raising nurseries. Conclusion: a key biotechnological tool for afforestation and biodiversity conservation.

• Intro: Bohr (1913) and Sommerfeld (elliptical orbits, 1916) models could not explain fine structure of spectral lines or the Zeeman effect; the vector atom model added two ideas – spatial quantisation and electron spin (Uhlenbeck and Goudsmit, 1925).
• Concept: the orbital and spin angular momenta of an electron are treated as vectors that can take only certain quantised orientations in space and combine vectorially (L + S = J).
• Principal quantum number (n = 1, 2, 3 …): size and energy of the orbit (shell K, L, M …).
• Orbital (azimuthal) quantum number (l = 0 to n−1): shape of the orbit / sub-shell s, p, d, f; orbital angular momentum = √[l(l+1)] ħ.
• Magnetic quantum number (m_l = −l … 0 … +l): orientation of the orbital in a magnetic field (2l+1 values) – explains the normal Zeeman effect.
• Spin quantum number (s = 1/2; m_s = +1/2 or −1/2): spinning of the electron about its own axis; total angular momentum quantum number j = l ± 1/2 and m_j – explain fine structure (e.g. sodium D1 and D2 lines) and anomalous Zeeman effect.
• Pauli's exclusion principle: no two electrons in an atom can have the same set of four quantum numbers (n, l, m_l, m_s) – basis of electronic configuration and the periodic table.
• Conclusion: The vector atom model bridged Bohr's theory and modern quantum mechanics; it underlies spectroscopy, lasers and MRI.

• Intro: The District Mental Health Programme (DMHP) is the key component of the National Mental Health Programme (1982); in Tamil Nadu it began as a pilot in Tiruchirappalli in 1997 and now covers all districts, implemented by the Directorate of Medical and Rural Health Services under the National Health Mission. The Erwadi fire tragedy (2001) gave impetus to humane, community-based care.
• Objectives: shift care from mental hospitals to primary and district health care; early detection and treatment; reduce stigma; prevent mental illness and suicide; integrate mental health with general health and social development; reach the underserved.
• District team: psychiatrist(s), clinical psychologist, psychiatric social worker, psychiatric nurse, multipurpose health worker and data-entry operator, based at the district headquarters hospital.
• Primary activities: OPD and in-patient care with free medicines; outreach/satellite clinics at PHCs, CHCs and sub-district hospitals; special clinics (suicide prevention, de-addiction, geriatric, child and adolescent); prison visits; life-skills education in schools and colleges; training of doctors and health workers; IEC campaigns.
• Tamil Nadu innovations: 104 tele-counselling for suicide prevention; follow-up counselling for suicide attempters; de-addiction centres; Emergency Care and Recovery Centres for wandering persons with mental illness (reuniting them with families); the 'Markkam & Maruthuvam' (faith and medicine) project at the Erwadi dargah, modelled on the 'Dava–Dua' approach, referring visitors to the psychiatric team at the Government Hospital, Erwadi.
• Community-centred approach: home visits and follow-up; treatment camps in villages; involving families as caregivers, ASHAs/village health nurses, teachers, NGOs, self-help groups and religious places; de-institutionalisation and rehabilitation; anti-stigma awareness; linkage with Tele-MANAS (14416) and the rights-based Mental Healthcare Act 2017 (Sec. 115 – presumption of severe stress in attempted suicide).
• Gaps: shortage of psychiatrists and psychologists, low budget share, drug-supply gaps, stigma, weak data and follow-up, limited urban workplace and adolescent coverage.
• Conclusion: Strengthening human resources, community volunteers and digital tele-mental health can make DMHP the backbone of 'mental health for all' in Tamil Nadu.

• Intro: The 42nd Constitutional Amendment Act, 1976, enacted during the Emergency on the recommendations of the Swaran Singh Committee, made such sweeping changes that it is called the 'Mini-Constitution'.
• Preamble: added 'Socialist', 'Secular' and 'Integrity' ('unity and integrity of the Nation').
• Fundamental Duties: new Part IVA, Article 51A – ten duties (on the Swaran Singh Committee's recommendation).
• Directive Principles: new Articles 39A (equal justice and free legal aid), 43A (workers' participation in management), 48A (protection of environment, forests and wildlife); Article 39(f) on children; Article 31C extended to give all DPSPs primacy over Articles 14 and 19 (this extension was struck down in Minerva Mills, 1980).
• Federal changes: five subjects moved from the State List to the Concurrent List – education, forests, weights and measures, protection of wild animals and birds, administration of justice (constitution of courts other than SC/HC); Article 257A allowed deployment of central armed forces in States.
• Executive and legislature: President bound by the advice of the Council of Ministers (Article 74); term of the Lok Sabha and State Assemblies extended from 5 to 6 years; Articles 323A and 323B for tribunals.
• Judiciary curtailed: Articles 32A, 131A, 144A, 226A and 228A restricted judicial review (omitted by the 43rd Amendment, 1977); Article 368(4) and (5) barred review of amendments – struck down in Minerva Mills (1980) as violating the basic structure (Kesavananda Bharati, 1973).
• Analysis and conclusion: it strengthened socio-economic goals and introduced duties, but centralised power and weakened checks; the 43rd (1977) and 44th (1978) Amendments undid much of it – the 44th restored the 5-year term and added safeguards on Emergency ('armed rebellion', written Cabinet advice) – showing the resilience of the basic structure.

• Intro: A Citizen's Charter is a public document in which an organisation declares its services, standards, time-limits and grievance redress to citizens; it originated in the UK (1991, John Major); India adopted it after the Conference of Chief Ministers (1997), coordinated by the Department of Administrative Reforms and Public Grievances (DARPG).
• How it empowers: information – citizens know what services they are entitled to; standards and time-limits create clear expectations; choice and consultation with users; courtesy and helpfulness; grievance redress and remedies; value for money.
• Accountability tools: Sevottam model (DARPG) for service quality; CPGRAMS online grievance portal; Right to Information Act 2005; Right to Public Services laws in several States; Second ARC (12th Report, 'Citizen Centric Administration') recommended charters with specific standards and penalties.
• Tamil Nadu: e-Sevai centres, single-window and online services, 'Makkaludan Mudhalvar' and 'Mudhalvarin Mugavari' grievance mechanisms, CM helpline 1100 – taking services to the people's doorstep.
• Limitations: charters are not legally enforceable; prepared top-down without consulting users; vague standards; poor publicity and awareness; no compensation for delay; frequent transfers and lack of staff training.
• Way forward: statutory backing with time-bound delivery and compensation (the lapsed Citizens' Right to Grievance Redress Bill, 2011 idea), periodic review with citizen feedback, digital dashboards, social audit and capacity building.
• Conclusion: A charter empowers citizens only when it is enforceable, measurable and owned by both officials and people – turning 'subjects' of administration into 'stakeholders'.

• Intro (choose cyclones/floods): Tamil Nadu's 1,076 km coastline faces north-east monsoon cyclones and floods (Chennai floods 2015; cyclones Thane 2011, Vardah 2016, Gaja 2018, Michaung 2023, Fengal 2024; southern TN extreme rain December 2023).
• Existing system – forecasting: IMD (Regional Meteorological Centre and Cyclone Warning Centre, Chennai; colour-coded warnings), Doppler weather radars, satellites (INSAT series), INCOIS tsunami and storm-surge warnings (since 2007), Central Water Commission flood forecasts.
• Existing system – State dissemination: Tamil Nadu State Disaster Management Authority and State Emergency Operation Centre; TNSMART web/app for hazard alerts and vulnerability mapping; Common Alerting Protocol SMS alerts; Chennai flood warning system (C-FLOWS) developed with national scientific institutions; first responders and multi-purpose cyclone shelters.
• Strengths: cyclone track and landfall forecasts are now accurate several days ahead; timely evacuation has sharply reduced deaths compared with earlier cyclones; good coordination with NDRF/SDRF, fishermen warnings, pre-positioning of resources.
• Weaknesses: forecasting extreme localised rainfall (cloudburst-like events, e.g. Thoothukudi–Tirunelveli, December 2023) remains poor; urban flood warnings lack street-level detail; reservoir-release coordination (Chembarambakkam, 2015) and encroached water bodies; last-mile reach to the elderly, migrants, fishermen at sea; alert fatigue; limited impact-based forecasting.
• Way forward: impact-based and ward-level forecasting, more radars and automatic rain gauges, AI-based nowcasting, integration of dam operations, restoration of tanks and drainage, community-based early-warning volunteers (Aapda Mitra), regular drills.
• Conclusion: TN's cyclone EWS is a success story in reducing deaths, but flood EWS must move from 'forecast to impact' to reduce economic losses – in line with Sendai Framework Target G and the UN 'Early Warnings for All' initiative.

• Intro: Hydropower is a clean, renewable and flexible source (large hydro was declared renewable energy in 2019); India's installed large-hydro capacity is around 47 GW against an assessed potential of about 145 GW (CEA), most of it in the Himalayan rivers.
• Physical factors: perennial and adequate water flow; steep gradient/head (waterfalls, narrow gorges); rainfall regime and monsoon variability; catchment area; hard rock base for dams.
• Constraints: siltation of reservoirs; seismic and landslide-prone Himalaya, glacial lake outburst floods (e.g. Chamoli 2021, Sikkim 2023); climate change altering flows.
• Economic and social factors: high capital cost and long gestation; difficult terrain and transport; transmission from remote areas; land acquisition, displacement and rehabilitation; environmental clearances and protests (e.g. Narmada, Silent Valley); inter-state and international water disputes; competing uses (irrigation, drinking water).
• Role of northern (Himalayan) rivers: snow- and glacier-fed, perennial, steep slopes – greatest potential (Brahmaputra basin has the largest share); projects: Bhakra-Nangal (Sutlej), Tehri (Bhagirathi), Nathpa Jhakri (Sutlej), Salal and Uri (Chenab/Jhelum), Subansiri Lower (Arunachal–Assam).
• Role of peninsular rivers: rain-fed and seasonal, but steep Western Ghats escarpment gives good heads; projects: Koyna (Maharashtra), Sharavathi (Karnataka), Idukki (Periyar, Kerala), Srisailam and Nagarjuna Sagar (Krishna); Tamil Nadu – Pykara (1932, first in TN), Mettur (Kaveri), Kundah, Kodayar and Kadamparai pumped-storage.
• Future: pumped-storage projects to balance solar and wind power, small hydro, safer dam engineering (Dam Safety Act 2021), basin-wise planning.
• Conclusion: Himalayan rivers are India's hydropower reservoir for the future, while peninsular rivers provide important regional and peaking power – sustainable development requires balancing energy with ecology and people.

• Intro: India, the world's largest producer of millets, proposed the UN International Year of Millets 2023; millets were notified as 'Nutri-Cereals' (2018) and branded 'Shree Anna' (Union Budget 2023–24); the Indian Institute of Millets Research, Hyderabad is the Global Centre of Excellence. Tamil Nadu runs its own Millet Mission (ragi, kambu, cholam, thinai, samai, varagu, kuthiraivali).
• Mission components: area expansion and seed distribution under the National Food Security Mission (Nutri-Cereals), MSP procurement, inclusion in PDS/ICDS/PM-POSHAN, processing units, FPOs, startups and the PLI scheme for millet-based foods, awareness campaigns.
• Economic impact – farmers: climate-resilient crops needing less water, fertiliser and inputs – suited to rainfed, dry lands; lower cost of cultivation and risk; crop diversification; income through MSP and value addition.
• Economic impact – rural livelihoods: employment in processing, value-added products (flour, flakes, snacks), women's SHGs and FPOs; export opportunities.
• Health impact: rich in dietary fibre, protein, iron, calcium (finger millet/ragi is very rich in calcium), zinc and B-vitamins; low glycaemic index – helps manage diabetes and obesity; gluten-free; combats anaemia and 'hidden hunger' among women and children when included in noon-meal and anganwadi menus.
• Environmental co-benefits: low water footprint, short duration, fewer pests, carbon-friendly – supports sustainable agriculture.
• Challenges: low yields and productivity, weak procurement and storage, drudgery in de-hulling, short shelf life, low consumer demand and price, limited seed varieties; risk that benefits go to processors rather than small farmers.
• Conclusion: With better seeds, assured procurement, decentralised processing and inclusion in public nutrition schemes, the millet mission can deliver both farm income and nutrition security to rural communities.

• Intro: Agricultural marketing covers assembling, grading, storage, transport and sale of farm produce; problems include many intermediaries, distress sales, inadequate regulated markets, poor storage and price volatility – farmers get a small share of the consumer rupee.
• Suggestions (committees): Royal Commission on Agriculture (1928) led to regulated markets; Shankarlal Guru Committee (2001) on market reforms; Model APMC Act (2003) – private markets, direct marketing, contract farming; Model Agricultural Produce and Livestock Marketing Act (2017) – single state market, e-trading, warehouses as markets; Ashok Dalwai Committee on Doubling Farmers' Income – Gramin Agricultural Markets (GrAMs) and market-led extension.
• Steps – institutions: APMC regulated markets; National Agricultural Market (e-NAM, launched 14 April 2016) for online, transparent trading across mandis; Warehousing Development and Regulatory Authority (2007 Act) with negotiable warehouse receipts; Agmarknet price information; AGMARK grading.
• Steps – price support: Minimum Support Price for 22 mandated crops, PM-AASHA (2018), Price Stabilisation Fund, Operation Greens (tomato, onion, potato, later all fruits and vegetables).
• Steps – infrastructure and collectives: Agriculture Infrastructure Fund (Rs 1 lakh crore, 2020); formation of 10,000 Farmer Producer Organisations; Kisan Rail; cold chains under PM Kisan SAMPADA Yojana; ONDC/e-commerce linkages.
• Tamil Nadu: Uzhavar Sandhai (farmers' markets, 1999) for direct sale to consumers; regulated markets under the TN Agricultural Produce Marketing (Regulation) Act; e-NAM mandis; cold storages, pledge loans, and price information through the agri-marketing department.
• Remaining issues: limited reach of e-NAM inter-state trade, few mandis per area, the 2020 farm laws repealed in 2021, need for assaying labs and logistics; draft National Policy Framework on Agricultural Marketing (2024) proposes further reform.
• Conclusion: Strengthening FPOs, digital markets, storage and price support can ensure 'one nation, one market' with fair prices for farmers.

• Intro: The Finance Commission is a constitutional, quasi-judicial body under Article 280, constituted by the President every five years (or earlier); qualifications are laid down by the Finance Commission (Miscellaneous Provisions) Act, 1951; the first FC was chaired by K. C. Neogy (1951).
• Functions (Article 280(3)): (a) distribution of the net proceeds of shareable taxes between the Union and States (vertical) and among States (horizontal); (b) principles governing grants-in-aid to States out of the Consolidated Fund of India (Article 275); (bb)/(c) measures to augment the Consolidated Fund of a State to supplement the resources of Panchayats and Municipalities (added by the 73rd and 74th Amendments); (d) any other matter referred by the President (e.g. disaster management financing, fiscal consolidation).
• Fifteenth Finance Commission (Chairman N. K. Singh; 2021–26): States' share 41% of the divisible pool (the 14th FC had raised it to 42%; 1% adjusted for J&K reorganisation).
• Horizontal criteria (15th FC): income distance 45%, population (2011) 15%, area 15%, forest and ecology 10%, demographic performance 12.5%, tax and fiscal effort 2.5%; Tamil Nadu's share is about 4.08%.
• Grants: revenue-deficit grants, local-body grants (rural and urban, with conditions such as audited accounts), disaster-management grants (SDRF/NDRF), sector-specific and State-specific grants; fiscal-deficit roadmap for States.
• Sixteenth Finance Commission (Chairman Arvind Panagariya) covers 2026–31.
• Issues: recommendations are advisory, though usually accepted; rising cesses and surcharges outside the divisible pool shrink States' share; criteria penalise better-performing States like Tamil Nadu (lower population growth, higher income); demands from States for 50% devolution and a permanent FC secretariat.
• Conclusion: The Finance Commission is the 'balancing wheel of fiscal federalism'; a fair, predictable formula that rewards efficiency and equity strengthens cooperative federalism.

Diagram / table: Pie chart of 15th FC horizontal devolution criteria (45 / 15 / 15 / 10 / 12.5 / 2.5) and a vertical-devolution bar (13th 32% → 14th 42% → 15th 41%).

• Intro: Starlink is a satellite-internet service of the US company SpaceX that uses a mega-constellation of Low Earth Orbit (LEO) satellites to provide broadband anywhere on Earth, especially where fibre and mobile networks cannot reach.
• Feature – LEO constellation: thousands of small satellites orbiting at roughly 550 km (compared with about 36,000 km for geostationary satellites) – low latency suitable for video calls and online services.
• Feature – technology: flat phased-array user terminal ('dish') that self-aligns; laser inter-satellite links; ground gateways; reusable Falcon 9 rockets lower launch cost; direct-to-cell services being developed.
• Feature – uses: rural and remote connectivity (hills, islands, forests), disaster response when terrestrial networks fail, maritime and aviation internet, defence and backup networks; complements BharatNet in India.
• India status: satellite spectrum is assigned administratively (not auctioned) under the Telecommunications Act 2023; competitors include Eutelsat OneWeb, Jio–SES and Amazon's Kuiper. (Latest, after this exam: Starlink received the DoT's GMPCS licence in June 2025 and IN-SPACe authorisation in July 2025.)
• Challenges – economic and access: high cost of the terminal and monthly charges for rural users; weather (heavy rain) and capacity limits in dense areas.
• Challenges – security and sovereignty: data localisation, lawful interception and security clearance, dependence on a foreign private company (concerns highlighted by its use in conflicts), unauthorised terminals; level playing field with telecom operators over spectrum pricing.
• Challenges – space environment: space debris and collision risk (Kessler syndrome), interference with astronomical observations (light pollution, radio noise), orbital crowding. Conclusion: with proper regulation, affordability and indigenous alternatives (ISRO/Indian private constellations), satellite broadband can bridge India's digital divide.
