It could be an example, an argument or an illustration. Put the topic for the paragraph in the first sentence so it ties in with the hook at the end of the introduction. After you have written a few sentences about this main topic, end the paragraph with another hook that transitions the reader into the second paragraph.
The Second Paragraph of the Body
The second strongest statement belongs here, and you follow basically the same pattern you did with the first paragraph, using transition sentences at the beginning and the end. All the topics including this one should relate to the thesis statement and provide support for it.
The Third Paragraph of the Body
The third paragraph is the last one of the body and would contain a third topic which supports the thesis statement. It should be the weakest of the three, and you need to set up transitions between paragraphs just like you did in the first and second paragraphs. The hook at the end of this paragraph should be designed to lead into the conclusion, which is the fifth and final paragraph of the five paragraph style of essay.
