12. (D)
Question Type: Analyze Argument Structure
The argument starts with background information and an opposing point (the novels are similar, so plagiarism might be involved), but then pivots to the author’s main conclusion with the word "however." The author concludes that it’s probably not plagiarism, but rather coincidence. The author then supports his/her conclusion with a supporting premise at the end of the argument. This is a very common argument structure: OPPOSING POINT --- CONCLUSION --- SUPPORTING PREMISE. Answer (D) correctly expresses the main conclusion.
(A) restates some of the background information given for the argument.
(B) restates the opposing point.
(C) restates the supporting premise.
(E) gives a cause/effect relationship that does not accurately represent the conclusion made in the passage.
