This chapter discusses researching, supporting, and delivering ideas. It covers researching your topic, using supporting materials like explanations, comparisons, illustrations, examples, statistics, and expert opinions to clarify, prove, and add interest. It discusses improving delivery through body language, gestures, voice, language, and confidence. The key purposes of supporting materials are to clarify, prove, and add interest to ideas. Explanations should be brief and used for clarification, not proof. Comparisons show similarities or differences to make things easier to understand. Illustrations and examples are used for both proof and clarification. Statistics and expert opinions are also discussed.
