The format for writing answers in the UPSC Mains examination typically emphasizes clarity and structure. Answers should begin with a concise introduction highlighting key points, followed by well-organized body paragraphs that elaborate on the argument or discussion. Using headings, subheadings, and bullet points where appropriate can enhance readability. Each answer should be concluded with a concise summary or opinion that encapsulates the main argument or key takeaway. Adhering to an effective and coherent structure ensures that answers are not just factually accurate but also engaging and straightforward for the evaluator to assess.
