The first thing I tell people is that a good question has to be a question. I warn them that if they take a statement and try to raise the pitch of their voices at their end of their sentences, we won’t be tricked. I tell the audience that grammarians will agree that there’s no such thing as a two-part question. I tell people that if they think they have a two-part question, what they really have are two questions, and that they should just pick the better of the two.
