@CMas, well, if you look at the first-person perspective, if extrasensory perception exists --> everyone will believe it --> people with those powers would easily convince everyone --> will be rich, which would equate to him saying, since the general public doesn't believe, then it's not real.

The second person doesn't refute that it would satisfy all skeptics, as B says; in fact, he says you can't please any skeptics, which takes B out entirely. So what he's saying is that just because the general population believes it's true doesn't mean it's not real; it is just that it hasn't had a chance to prove it, which is why D fits best.

I notice that I get part of the answer and miss the others in each question.
