UPSC Prelims 2015— Question 52

Correct answer: Option D. Namdapha National Park in Arunachal Pradesh spans a remarkable altitudinal range and supports vegetation and climatic conditions from tropical through subtropical and temperate zones to alpine or near-arctic conditions at high elevations. This exceptional vertical range explains the description in the question. Option-wise analysis: Option A: “Khangchendzonga National Park” is incorrect. It does not match the specific fact, definition, institutional role, geographical association, or constitutional/economic principle required here. The key distinction is the one identified in the core explanation, so this option can be eliminated. Option B: “Nandadevi National Park” is incorrect. It does not match the specific fact, definition, institutional role, geographical association, or constitutional/economic principle required here. The key distinction is the one identified in the core explanation, so this option can be eliminated. Option C: “Neora Valley National Park” is incorrect. It does not match the specific fact, definition, institutional role, geographical association, or constitutional/economic principle required here. The key distinction is the one identified in the core explanation, so this option can be eliminated. Option D: “Namdapha National Park” is correct. It directly matches the factual or conceptual requirement tested by the question and is supported by the principle explained above. Prelims takeaway: Focus on the precise institutional role, constitutional provision, geographical association, or technical definition being tested. UPSC questions often place a broadly familiar fact beside a narrowly incorrect qualifier; identifying that qualifier is essential for elimination.
