Sample Questions (2025)

2025 Q5Science & Tech
Consider the following substances : I. Ethanol II. Nitroglycerine III. Urea Coal gasification technology can be used in the production of how many of them?
(a) Only one
(b) Only two
(c) All the three
(d) None
Answer: (b)
Trap: Partial Truth
Coal gasification produces syngas (CO + H2), which can be used to make ethanol (via Fischer-Tropsch or fermentation routes) and urea (via ammonia synthesis from H2). Nitroglycerine requires glycerol + nitric acid; while nitric acid can be derived from syngas route, the direct association is weaker. Candidates may pick (c) thinking all chemical synthesis traces back to syngas.
2025 Q12Environment
Consider the following statements : Statement I : At the 28th United Nations Climate Change Conference (COP28), India refrained from signing the 'Declaration on Climate and Health'. Statement II : The COP28 Declaration on Climate and Health is a binding declaration; and if signed, it becomes mandatory to decarbonize health sector. Statement III : If India's health sector is decarbonized, the resilience of its health-care system may be compromised. Which one of the following is correct in respect of the above statements?
(a) Both Statement II and Statement III are correct and both of them explain Statement I
(b) Both Statement II and Statement III are correct but only one of them explains Statement I
(c) Only one of the Statements II and III is correct and that explains Statement I
(d) Neither Statement II nor Statement III is correct
Answer: (c)
Trap: Partial Truth
Statement II is wrong - the COP28 Declaration on Climate and Health is NOT binding, it's voluntary. Candidates who assume COP declarations are binding will pick (a) or (b). Statement III is correct - rapid decarbonization could compromise healthcare resilience in a developing country, which explains India's hesitation.
2025 Q14Environment
Consider the following statements : Statement I : Article 6 of the Paris Agreement on climate change is frequently discussed in global discussions on sustainable development and climate change. Statement II : Article 6 of the Paris Agreement on climate change sets out the principles of carbon markets. Statement III : Article 6 of the Paris Agreement on climate change intends to promote inter-country non-market strategies to reach their climate targets. Which one of the following is correct in respect of the above statements?
(a) Both Statement II and Statement III are correct and both of them explain Statement I
(b) Both Statement II and Statement III are correct but only one of them explains Statement I
(c) Only one of the Statements II and III is correct and that explains Statement I
(d) Neither Statement II nor Statement III is correct
Answer: (a)
Trap: Partial Truth
Candidates may think Article 6 is only about carbon markets (Statement II) and not about non-market approaches, leading them to pick (c). However, Article 6.8 explicitly covers non-market approaches. Both II and III explain why Article 6 is frequently discussed.
