There are questions and there are questions.  In this case these "questions" are more accusatory in nature than asking for enlightenment.  If the former were not so they would have accepted the information and wrapped themselves in their cloaks and silently stolen away to their various castles.  The first time a thing is asked, it is indeed a question.  After they have the answer and continue to ask, it is no longer a question but an accusation wrapped in a question.
