Explanation, spoiler by Brook Miscoski)
Actually, number 5 cannot be answered right off the bat. The
tricky thing about this test is that just because an answer is correct
doesn't mean it's the RIGHT answer. It's hard to explain, but
number 19 is a good example. All of the choices are correct, but
only one is right, as suggested by the other questions.
