Reasons and examples

A closing idea should appear in a conclusion.

In a conclusion, a closing idea should be included. A conclusion is the final paragraph or section of an essay or paper, where the main points are summarized and the overall message is reinforced. The closing idea should bring the discussion to a natural end and leave a lasting impression on the reader, emphasizing the significance of the topic or the thesis statement. It should not include an introduction, supporting details, or reasons and examples, as these elements are typically found in the body paragraphs of the essay or paper.

In a conclusion, the following elements should appear:

1. A closing idea: A conclusion should provide a final thought or summary of the main points discussed in the body of the text. It serves as the last opportunity to leave a lasting impression on the reader.

To include a closing idea in your conclusion, you can review the main points from your essay or paper and emphasize their significance or relevance to the overall topic. This allows you to tie everything together and provide a sense of closure.

2. Reasons and examples: While the body paragraphs are where you typically present your supporting details, a conclusion can briefly restate or summarize the most important reasons and examples that were discussed.

By including reasons and examples in your conclusion, you reinforce your main arguments and remind the reader of the evidence you provided earlier. However, keep in mind that the conclusion should be concise, so only include the most relevant and impactful supporting details.

On the other hand, an introduction should not appear in the conclusion. The introduction serves to introduce the main topic and provide background information, while the conclusion is meant to summarize and wrap up the discussion.

To effectively craft a conclusion, it's important to revisit your main points, restate your thesis statement (if appropriate), and leave the reader with a final thought or reflection on the topic.
