I think E is the correct answer and the reasons are as following.
choice A:the reviewer states that trust the books that he knows the cities' conditions are true but did not mentioned that he trust the writers.
choice B: the text does not mention any explicit atitude of the reader about novels set in cities that are strange to him. In other words, the reviewer may like a story based on fictitious situation.
choice C:although the writer acclaimed that he liked the second book set in San Francisco as well as the first book. However the first book may set in a city he is farmiliar with besides San Francsico.
choice D is obiviously fallacious, also because the reviewer didnot mention anything about the books with the description of cities he does not well
