First question of last passage:

Why not A - I had it down to two.

Last paragraph of third passage:

What is the best thing to do on test day if I'm not sure about the content of this entire paragraph. I understood it was the author's point of view and it was generally disagreeing with the first two paragraphs - but I wasn't too sure about what the first two paragraphs really were... I had A's view circled, "disagree" with a question mark on the side notes.

Re-read entire passage quickly? Re-read third paragraph? Or plug and chug onto the questions?

I just did this PT yesterday. I would say A is wrong because passage B doesn't say anything concrete about continuous sounds=pleasure. It sounds extreme mismatches cause displeasure, but doesn't say much more than that.
