When faced with ambiguous questions in the UPSC exam, candidates should adopt a structured approach. First, they should carefully analyze the question to identify its core components. Clarifying uncertainties through applicable knowledge and framing their answer around known concepts can help. If multiple interpretations exist, they should present their understanding clearly while backing it with relevant examples or theories. Prioritizing a coherent argument over a perfect answer can enhance clarity. Remaining calm and composed is vital, allowing the candidate to think critically rather than succumbing to stress. Time management during the exam is also crucial to ensure thoughtful responses.
