Why is it essential to summarize key points in a conclusion?

Summarizing key points in a conclusion is essential because it allows the writer to reiterate the main ideas presented throughout the text and reinforce the central argument. This consolidation helps provide clarity to the reader, ensuring that the most important themes and messages are highlighted and easily remembered. By summarizing, the writer can effectively remind the audience of the significance of the discussion and the rationale behind the conclusions drawn. This technique also enhances the cohesiveness of the text by linking back to the arguments made earlier, leaving the reader with a clear understanding of the topic at hand.

In contrast, extending the discussion or introducing new elements in the conclusion may confuse the audience, as they expect the conclusion to encapsulate rather than expand the ideas previously discussed. Confusing the reader about the main message can undermine the effectiveness of the entire piece. Thus, the focus should always be on reinforcing what has been articulated, solidifying the overall argument.
