The lazy version of that, which I recommend, is always deny the first answer. Usually I deny for some obvious reason, but sometimes I just say "isn't that wrong?"
That's a useful trick but I have noticed when I do that it goes in circles a where it suggests "A", I say it's wrong, it suggests "B", I say that's wrong, it suggests "C", I say that's wrong, and then it suggests "A" again.
Usually for it to get a correct answer, I have to provide it a bit of context.
