I agree with the above contributor with exception to the George W. statement. You can also answer a rhetorical question, however, look at the expression on the face of the one who asked the question and you will see that deer in the headlights look.
Just think of those times when you ask someone a very simple question and you get bombarded with an over elaborate answer. You know, the kind of answer that had just a bit more information than you really wanted or more than was actually necessary?
