Current affairs significantly shape opinion-based questions in the UPSC mains exam by providing relevant context and real-world examples that test candidates’ understanding of contemporary issues. As the exam aims to assess analytical and critical thinking abilities, staying updated on current events enables candidates to formulate well-informed arguments and opinions. This knowledge helps in articulating thoughts effectively, demonstrating awareness of socio-economic and political landscapes. Thus, candidates who actively engage with current affairs are better equipped to tackle these questions, showing their readiness to address issues pertinent to governance and public administration.
