• Question 1 of 5 1. Question Urbanisation is often presented as a sign of modern progress, yet many Indian cities struggle with unplanned growth, inadequate infrastructure, and rising environmental stress. Rapid construction and expanding road networks have increased pollution levels, while shrinking green spaces have reduced natural cooling and water recharge capacities. As cities absorb more people, water scarcity, waste mismanagement, and heat island effects intensify. Despite these challenges, urban planning frequently focuses on real estate expansion and commercial development rather than creating resilient, liveable urban ecosystems. Experts argue that unless Indian cities adopt sustainable urban planning—through improved public transport, green infrastructure, and climate-sensitive zoning—the long-term social and economic costs will surpass short-term gains from unregulated urban expansion. Which one of the following statements best reflects the corollary to the above passage? (a) Real estate expansion should be encouraged to accelerate urban economic growth. (b) Sustainable and climate-sensitive urban planning is essential to avoid long-term urban crises. (c) Urban environmental problems are inevitable and cannot be addressed by policy measures. (d) Citizens alone must take responsibility for reducing pollution in cities. Correct Answer: (b) Explanation: Option (b) is correct because the passage clearly argues that sustainable, climate-sensitive, and resilient planning is essential to prevent long-term environmental and social costs in cities. Option (a) is incorrect: the passage criticises unregulated real estate expansion as short-sighted. Option (c) is incorrect: the passage emphasises that policy choices—better planning, green infrastructure—can mitigate urban challenges. Option (d) is incorrect: responsibility is not placed on citizens alone but on systemic planning and governance reforms. Incorrect Answer: (b) Explanation: Option (b) is correct because the passage clearly argues that sustainable, climate-sensitive, and resilient planning is essential to prevent long-term environmental and social costs in cities. Option (a) is incorrect: the passage criticises unregulated real estate expansion as short-sighted. Option (c) is incorrect: the passage emphasises that policy choices—better planning, green infrastructure—can mitigate urban challenges. Option (d) is incorrect: responsibility is not placed on citizens alone but on systemic planning and governance reforms.

• Question 2 of 5 2. Question With reference to the above passage, the following assumptions have been made: I. Sustainable urban planning can significantly reduce long-term environmental and social risks in Indian cities. II. Prioritising short-term commercial development over ecological health will worsen the livability and resilience of cities. Which of the above assumptions is/are valid? (a) I only (b) II only (c) Both I and II (d) Neither I nor II Correct Answer: (c) Explanation: Assumption I is valid because the passage explicitly argues that measures like green infrastructure, efficient public transport, and climate-sensitive zoning strengthen resilience and reduce long-term risk. Assumption II is also valid, as the passage states that an excessive focus on real estate and commercial expansion increases environmental stress and undermines future urban livability.

• Question 3 of 5 3. Question Public health systems form the backbone of a nation’s well-being, yet investment in preventive healthcare often remains inadequate. While hospitals and specialised treatments receive attention, basic services such as early disease screening, nutrition programmes, sanitation, and vaccination coverage are frequently underfunded. This neglect disproportionately affects poor and rural populations, who suffer higher disease burdens due to lack of timely care. Experts warn that without strengthening preventive healthcare, rising cases of lifestyle and infectious diseases will overwhelm existing medical infrastructure. Building resilient health systems requires shifting focus toward prevention through greater funding, community awareness, and equitable access to primary healthcare services. Which one of the following statements best reflects the corollary to the above passage? (a) Public health crises can be solved only by building more hospitals and specialised facilities. (b) Strengthening preventive healthcare is essential to reduce long-term disease burden and protect vulnerable populations. (c) Rural communities are solely responsible for improving their own health outcomes. (d) Lifestyle diseases are inevitable and cannot be reduced by policy interventions. Correct Answer: (b) Explanation: Option (b) is correct because the passage clearly emphasises that preventive healthcare—screening, sanitation, nutrition, vaccination—is essential for reducing future disease burden and preventing health systems from being overwhelmed. Option (a) is incorrect: the passage warns against excessive dependence on hospitals without investing in prevention. Option (c) is incorrect: the passage calls for systemic reforms, not blaming communities. Option (d) is incorrect: the passage suggests that policy interventions can reduce disease burdens through prevention.

• Question 5 of 5 5. Question The price of cooking oil rose by 20%. A family reduced its consumption so that the expenditure increased only by 8%. If their earlier monthly consumption was 50 litres, what is the new consumption? (a) 44 litres (b) 45 litres (c) 46 litres (d) 47 litres Correct Answer: (b) Explanation: Initial price = ₹100 per litre. Initial consumption = 50 litres → Expenditure = 100 × 50 = ₹5,000. New expenditure = 5,000 + 8% of 5,000 = ₹5,400. New price = 100 + 20% of 100 = ₹120. So, 120 × new consumption = 5,400. New consumption = 5,400 ÷ 120 = 45 litres. Incorrect Answer: (b) Explanation: Initial price = ₹100 per litre. Initial consumption = 50 litres → Expenditure = 100 × 50 = ₹5,000. New expenditure = 5,000 + 8% of 5,000 = ₹5,400. New price = 100 + 20% of 100 = ₹120. So, 120 × new consumption = 5,400. New consumption = 5,400 ÷ 120 = 45 litres.
