1) The whole passage restricts the novels to cities the reviewer knows well. No other novels are mentioned. A talks about "any novel," which could include novels NOT in cities the reviewer knows well.
2) As Shun in another thread mentioned, novels are further restricted with the word "good": "This trust increases my enjoyment of a GOOD novel" Answer A says "ANY novel," which is far too broad for "a good novel"
3) The use of the word "virtually." While I haven't begun the quantifiers lesson, I do know that in everyday life, "virtually" is a synonym for "almost," so "virtually any novel" would be similar to "most novels," which fails the S/N test. I'd diagram it as follows: E --some-- TN (Book review enjoys novels --most-- trusted novelists) There aren't any quantifiers in the stimulus, so I don't think we can introduce one in the answer choice.
