A rhetorical question is a question that is not intended to be answered. It is used to make a point or to emphasize something. For example, the question “Who could forget the events of that day?” is a rhetorical question. It is not meant to be answered; rather, it is used to emphasize the importance of the events of that day.
Rhetorical questions are often used in persuasive speeches and writing. They can be used to make a point seem more forceful or to emphasize a particular point of view. For example, the question “Why should we continue to fund this program?” is a rhetorical question that is used to argue against the funding of the program.
