Rhetorical Questions :


Put a question mark at the end of a sentence that is, in fact, a direct question. Sometimes writers will simply forget. Rhetorical questions (asked when an answer is not really expected), by the way, are questions and deserve to end with a question mark:

How else should we end them, after all?

What if I said to you, "You've got a real problem here"?

Notice that the question mark here comes after the quotation mark and there is no period at the end of the statement.
