UPSC Prelims 2018— Question 94

**Concept and analysis:** Pakhui Wildlife Sanctuary, now commonly known as Pakke Wildlife Sanctuary or Pakke Tiger Reserve, is in Arunachal Pradesh. It is part of the Eastern Himalaya biodiversity region and is important for species such as the hornbills. It is not located in Manipur, Meghalaya or Nagaland. The question is testing precise UPSC-level identification rather than a broad association. The key is to distinguish the exact institutional, constitutional, historical, geographical, economic or scientific feature being asked. **Option-wise evaluation** **Option A:** Correct. Arunachal Pradesh directly matches the concept or factual identification established in the analysis. **Option B:** Incorrect. Manipur is a different institution, place, definition, proposition or description and does not satisfy the specific requirement of the question. **Option C:** Incorrect. Meghalaya is a different institution, place, definition, proposition or description and does not satisfy the specific requirement of the question. **Option D:** Incorrect. Nagaland is a different institution, place, definition, proposition or description and does not satisfy the specific requirement of the question. **UPSC takeaway:** The safest way to solve this type of question is to anchor the answer in the defining feature of the concept and then test every option against that feature. Closely related institutions or terms are often used as distractors. In statement-based questions, do not judge the option as a whole before checking each statement independently. In factual questions, compare the wording of each option with the exact definition, location, institutional role, chronology or scientific property. The correct answer follows from that verification rather than from familiarity with a keyword.
