A typical paper will have two-three sub topics for support. These will be stated at the start of each body paragraph, and also in your thesis. You already have your topic sentence, which is your claim. Now, use textual support and other data to prove this claim. Use books, the internet, and even videos to support your topic sentence. The commentary is the main part of any writing piece. Write your reaction to the support you have just provided. Include your opinions and beliefs about the topic.

Summary:
Add your topic sentences. Include claims, evidence, and commentary. Add your view to the end of the paragraph.
