Which question type doesn't necessarily have one correct answer and often does not call for a spoken response?

Rhetorical questions are designed to make a point or provoke thought rather than to elicit an answer. They are often used in speech or writing to engage the audience and emphasize a particular idea. Unlike other types of questions, a rhetorical question does not expect or require a direct spoken response. This quality makes it distinct from open questions, which invite discussion, and closed questions, which typically seek a specific answer. The nature of a rhetorical question allows it to serve as a persuasive device, encouraging the audience to reflect on the information presented rather than providing immediate feedback.
