Answer:
Rhetorical question
Explanation:
A rhetorical question is a question someone asks not to receive an answer but to emphasize a point. Rhetorical questions are often used for literary effect or as a tool of persuasion. The question might not have an answer at all (e.g. <em>Why me? Why bother? What's the meaning of life?</em>) or it might have an obvious answer (e.g. <em>Is rain wet? Do pigs fly?</em>). Rhetorical questions can also raise doubt (e.g. <em>Or was it?</em>).
As the word <em>rhetorical</em> implies, these questions are used as a figure of speech.
