What must a conclusion have to be accepted

A conclusion is what you will leave with your reader
It “wraps up” your essay
It demonstrates to the reader that you accomplished what you set out to do
It shows how you have proved your thesis
It provides the reader with a sense of closure on the topic.

In a conclusion paragraph, you summarize what you’ve written about in your paper. When you’re writing a good conclusion paragraph, you need to think about the main point that you want to get across and be sure it’s included. If you’ve already written a fabulous introductory paragraph, you can write something similar with different wording.
