What is the function of rhetorical questions in communication?

Rhetorical questions serve the function of engaging the audience and provoking thought by encouraging them to consider a particular issue or perspective without expecting a direct answer. This technique prompts listeners to reflect on their beliefs or feelings regarding the topic at hand, often leading them to arrive at conclusions on their own. By asking a question that doesn't necessarily require a response, the speaker creates a moment of interaction that can enhance the overall impact of the message being communicated. This method is commonly employed in persuasive speaking and can effectively keep the audience's attention while reinforcing the speaker's points.
