These 2 questions from UPSC Zoology Optional papers (2004–2026) fall outside the present syllabus of their paper – mostly from papers set on the older syllabus. We keep them here for completeness.
Each question ends with a code such as [2024/15m/3b] – the year, the marks, the word limit (where UPSC set one) and the question number in the paper.
