The document provides definitions and examples of the key elements of an introductory paragraph for a persuasive essay: the hook, topic, thesis statement, and rainbow sentence. The hook is meant to grab the reader's attention, the topic states what the essay will be about, the thesis gives the author's position, and the rainbow sentence lists the three main reasons for supporting the thesis. These elements are to be presented in order in the introductory paragraph, with the hook relating to the topic and a transition sentence leading to the body.
