College Composition CLEP Prep Practice Exam

Rhetorical questions are used in essays to engage readers and encourage them to think critically about the topic being discussed. They are not meant to provide evidence or create suspense, so options B and C are incorrect. Option D is also incorrect because the purpose of a rhetorical question is not to simply ask a question, but rather to make a statement in a way that promotes further thinking and reflection. Therefore, the only correct answer is A, as rhetorical questions are used to motivate and engage readers.
