The document defines rhetorical questions and discusses their purpose and use. A rhetorical question is a question asked to make a point or persuade rather than to get an answer, as the answer is obvious or implied. Rhetorical questions are used in debates to change people's minds or make them think of things in a new way. They can also be used to indirectly state a point rather than asking a question. The document provides examples of rhetorical and non-rhetorical questions and instructs readers to determine if a question is rhetorical by considering whether the asker truly wants new information from the answer.
