Understand the Directive Word First

Practice Questions With Model Approach

Q1. (10 marks, 150 words) Explain why the Minimum Support Price alone cannot solve the agrarian distress in India. Suggest an alternative approach.

Model approach: Start with what MSP does: assured price for 22 crops, procurement mainly of wheat and rice in a few States. Limits: it covers few crops and farmers, encourages water-intensive cropping, strains the food stock and does not solve small holdings, debt and weather risk. Alternatives: crop diversification, FPOs and e-NAM for markets, storage and food processing, direct income support, price deficiency payments, crop insurance. Conclude with an integrated income-based approach.

Q2. (10 marks, 150 words) What is 'jobless growth'? Examine its causes in India.

Model approach: Define it as growth in output without matching growth in jobs. Causes: capital-intensive growth, a services sector that uses skilled labour, an informal economy, automation, a skill mismatch and a weak manufacturing base. Suggest labour-intensive manufacturing, MSME support, skilling, apprenticeships and rural non-farm jobs.

Q3. (15 marks, 250 words) Examine the role of GST in strengthening cooperative federalism. What are its limitations?

Model approach: Introduction: GST (2017) replaced many taxes with a dual structure. Role: the GST Council is a joint forum of the Centre and the States where decisions need a three-fourths weighted majority, in which the Centre has one-third of the votes and the States together have two-thirds. Limitations: loss of fiscal autonomy for States, revenue concerns after the five-year compensation period ended in 2022, complex rate slabs, and disputes. Conclude with simpler rates, a dispute settlement system and trust between the Centre and the States.

Q4. (15 marks, 250 words) Discuss India's climate commitments and the issue of equity in global climate action.

Model approach: Mention the updated NDC (2022): reduce emission intensity of GDP by 45 per cent from the 2005 level by 2030, and 50 per cent of installed electric capacity from non-fossil sources by 2030, and the net-zero goal for 2070 announced at COP26 (Panchamrit). Equity: historical emissions of developed countries, low per capita emissions of India, the principle of common but differentiated responsibilities and the need for climate finance and technology. Challenges: coal dependence, energy demand, finance gap. Conclude with a just transition and the LiFE movement.

Q5. (10 marks, 150 words) Why is the Western Himalayan region prone to landslides and flash floods? Suggest mitigation measures.

Model approach: Causes: young, fragile fold mountains, steep slopes, heavy rain and cloudbursts, glacial lake outbursts, deforestation, unplanned roads, tunnels, hydropower and tourism. Mitigation: carrying-capacity studies, strict EIA, zoning, slope stabilisation, early warning systems, community preparedness and sustainable tourism.

Q6. (10 marks, 150 words) Discuss the institutional framework for disaster management in India.

Model approach: Describe the Disaster Management Act, 2005, and the three tiers: NDMA headed by the Prime Minister, State Disaster Management Authorities headed by the Chief Ministers and District Authorities headed by the District Magistrates or Collectors. Add the NDRF, the NIDM and the Sendai Framework (2015 to 2030) with its focus on risk reduction. Suggest better local capacity, funds and coordination.

Q7. (15 marks, 250 words) Left Wing Extremism requires both security and development responses. Discuss.

Model approach: Introduce the causes: tribal alienation, land and forest rights, poor governance and poverty. Security: the SAMADHAN doctrine, better intelligence, central forces and State police coordination. Development: roads, mobile connectivity, schools, the Forest Rights Act and the Aspirational Districts Programme. Challenges: terrain, trust deficit and local grievances. Conclude with a balanced approach: security for control, and development, dialogue and rights for lasting peace.

Q8. (10 marks, 150 words) What are the major cyber threats to critical infrastructure? Discuss India's response.

Model approach: Threats: ransomware, phishing, malware, DDoS attacks, supply chain attacks and state-sponsored hacking on power grids, banks and hospitals. Response: IT Act 2000, CERT-In, the NCIIPC for critical infrastructure, the Indian Cyber Crime Coordination Centre, the Digital Personal Data Protection Act 2023, and the cyber security strategy. Suggest capacity building, mandatory audits and international cooperation.

Q9. (10 marks, 150 words) How can Artificial Intelligence help in governance? What are the risks?

Model approach: Uses: targeting of welfare benefits, fraud detection, language translation (Bhashini), crop advisories, health diagnosis and traffic management. Risks: bias in data, privacy loss, lack of transparency, job losses and misuse like deepfakes. Suggest ethical guidelines, human oversight, strong data protection and public awareness.

Q10. (15 marks, 250 words) Evaluate the role of PM Gati Shakti and the National Logistics Policy in improving India's infrastructure and logistics.

Model approach: Introduce Gati Shakti (2021) as a GIS-based digital platform for multimodal connectivity, and the National Logistics Policy (2022) for reducing logistics cost. Merits: better coordination among ministries, fewer delays and overlaps, faster project planning, lower cost for industry. Challenges: land acquisition, funding, State-level coordination, skill gaps and last-mile connectivity. Conclude with the need for cooperative federalism and green logistics.

A Simple Structure for GS Paper 3 Answers

Add Value With Facts, Diagrams and Examples

GS Paper 3 rewards answers that bring in current and relevant material. Use the Economic Survey, government reports, schemes and recent events to support your points. A small flowchart or a table for causes and solutions can save words and make the answer attractive. Add an Indian example and, wherever possible, a global example. But avoid unverified figures: a general statement that is correct is better than a number that is wrong.

Linking Static and Current Topics

Most questions in this paper combine a basic concept with a current issue. For example, a question on climate commitments needs your static knowledge of the Paris Agreement and the recent policies. A question on cyber security needs the IT Act and the latest data protection law. Keep a short note for each topic with three parts: the concept, the government response, and the latest development. This three-part note works as a ready-made answer outline. Our environment notes, economy notes and internal security notes can help you build the base.

Sample Introduction and Conclusion

For Question 2, an introduction can be: "Jobless growth refers to a situation in which the economy expands, but employment does not grow at the same pace, so the benefits of growth do not reach many workers." A conclusion can be: "To make growth inclusive, India must link its manufacturing and services growth with skilling and labour-intensive sectors, so that every new unit of output creates decent jobs." Notice that both are short, clear and free of unnecessary words.

Common Mistakes in GS Paper 3

• Ignoring the directive word: A "discuss" answer cannot be a one-sided list.
• Giving only the problem: The way forward carries marks, so do not skip it.
• Writing generic answers: Use the specific schemes, institutions and laws.
• Poor time management: Leaving the last questions unwritten costs more marks than writing an average answer.
• No practice with a timer: Writing at home without a time limit hides the speed problem.
