Research plays a pivotal role in answering UPSC Mains questions effectively. Candidates are required to support their answers with factual data, relevant examples, and contemporary issues. Conducting thorough research helps gather information pertinent to the syllabus and current affairs, providing a well-rounded view of topics. This not only enhances the quality of responses but also demonstrates analytical abilities and depth of knowledge. Furthermore, when candidates cite statistics or case studies, they elevate their answers, making them more persuasive. Thus, a solid research foundation is integral to composing compelling narratives in the Mains examination.
