To effectively draft the introduction of an essay for UPSC, candidates should aim for a hook that captivates the reader's attention. This can be achieved by posing a rhetorical question or presenting a striking fact related to the topic. Following this, clearly defining the central thesis and outlining the key points to be discussed can provide structure. Ensuring that the introduction reflects relevance to current issues or debates in governance enhances its impact. Maintaining brevity while ensuring clarity is crucial. A well-crafted introduction sets the tone for the essay, prompting the examiner to engage with the subsequent arguments presented.
