Speaking to Ms. Moore's comment as to why we would have four as opposed to three--because you were questioning the number--right now our chair is a Conservative. So it would make sense to have four people, as opposed to three, so that when we have a witness here, and the rounds of questioning occur, we could have a government member pose the question, because the chair is supposed to remain neutral and out of the questioning. That is the reason for the four.
