There is no question you can ask that will either illuminate the situation or pose any sort of difficulty for the psychic.
When you are dealing with a psychic or belief in psychics, you are dealing with an entirely closed system of thought, wherein any outcome is considered either evidence for the claim/belief or at least compatible with it. If you ask her a factual question and she guesses right, or partly right, this will be deemed evidence of her gift. If she gets it wrong, she has at least a dozen ways to wriggle out of it:
‘I never said my gifts work 100% reliably, all the time’
‘I’m just doing my best to interpret the impressions I get, and it’s not a perfect science’
‘If what I’m saying to you doesn’t seem right now, it will do later on’
‘On the psychic level, we sometimes have to interpret things in a symbolic or an emotional way, and not get too hung up on the literal meanings of words’
‘I sense that this will mean something to someone close to you, even if it doesn’t seem to make sense to you’
‘I think that you perhaps have a rather skeptical, closed-minded point of view, and my gifts don’t work for closed-minded people’
‘I don’t need proof, I know my gifts are real’
‘Maybe I wasn’t very successful here for you, but I have testimonials from hundreds of people from all walks of life going back over ten years… you’re not telling me they are all wrong or all gullible’
…and so on.
You cannot meaningfully either debate or evaluate psychic powers, any more than you can evaluate a hope or a wish. Psychic powers are as real as you want them to be, no more and no less. Some people want to believe in the delusion because it offers some sort of emotional or psychological crutch. Others don’t.
The only fact that needs to be stated, and clearly understood, is that just because something looks psychic, this doesn’t mean it actually is. I have given more ‘test conditions’ demonstrations of ‘psychic ability’ for the media than anyone else in the world (i.e. without pretending it’s actually real, and with the truth always tactfully revealed at the end). Among other things, I ‘talked to the dead’ working with a room of complete strangers, for ABC ‘Prime Time’, in front of an estimated ten million viewers.
When you know the right techniques, there is no point or question that a psychic cannot easily handle or evade.
