Which question doesn't need an answer?
A rhetorical question is a figure of speech in the form of a question that is asked to make a point rather than to elicit an answer. Though a rhetorical question does not require a direct answer, in many cases it may be intended to start a discussion or at least draw an acknowledgement that the listener understands the intended message.
A common example is the question "Can't you do anything right?" This question, when posed, is intended not to ask about the listener's ability but rather to insinuate the listener's lack of ability.
