What is a rhetorical question?

A rhetorical question is a figure of speech that is posed for its persuasive effect rather than to elicit a direct response from the audience. It often encourages the audience to think critically or reflect on the issue being discussed without expecting them to reply. This literary device is effective in public speaking as it engages the audience's interest and prompts them to consider a viewpoint or argument presented by the speaker.

This type of question can be used to emphasize a point or invoke emotion, thereby influencing the audience’s mindset. For instance, a speaker might ask, "Who wouldn't want to live in a world free from pollution?" This prompts the audience to consider the implications and feelings surrounding the topic, even though the question does not require a verbal response.
