Understanding historical context enriches answers during UPSC exams by providing a framework for the analysis of current events. It allows candidates to draw parallels between past and present situations, adding depth to their responses. Incorporating historical insights can help in explaining the origins of issues, thereby enhancing argument validity. Furthermore, referencing significant events or trends can demonstrate a candidate's grasp of the evolution of societal norms and policies. This contextual knowledge not only strengthens essays but also enhances the overall quality of answers in subjects like history, polity, and sociology.
