I think the men either do have problems with the answers on all these questions, or he is just a disguised elder who wants to nail you or make you a fool if you answer one of these questions in a not proper way. If I were you, I would only take all these questions in one sack turn them back to him (perhaps a little bit converted) and ask him why he does not ask the elders in his congregation for the answer. This naturally in his own name openly and amongst all other friends. If he does, he will have no chance do get baptized or if he is baptized, he will be Df.sh.
I think that such an experience will make him understand that the org. is not guided by god, but by greedy men, just concerning of their own power.
