Here's a breakdown:
* Restating the thesis: The conclusion should reiterate the main argument, but using different language than the introduction. This helps to emphasize the key point and tie the entire essay together.
* Summarizing key points: The conclusion should briefly summarize the main supporting arguments you presented in the body paragraphs. This reinforces the reader's understanding of your evidence and analysis.
* Leaving a lasting impression: The conclusion should offer a final thought or reflection that leaves a lasting impression on the reader. This can be a call to action, a prediction, or a broader perspective on the topic.
In short: While restating the thesis is a crucial part of a concluding paragraph, it's not the only element. A strong conclusion effectively combines restatement with a brief summary and a thought-provoking final statement.
