Congrats on those that got it right. I thought they were pretty tricky.
For A) icandy gave a good explanation on the right answer.
For C) This is the OE -
Although the question stem contains a specific line reference, the words would most likely agree indicate that the correct answer to this question depends on making an inference. First, it is worth noting that the beginning of the sentence relays a fact about the author’s approach to the book: the author does not...challenge the customary list of Baroque characteristics. The author of the passage suggests in the second part of the sentence that some students of art history would perceive this refusal to question custom as insufficient academic rigor. The correct answer, then, will identify what, to the author of the passage, would constitute sufficient academic rigor.
a) This is a corruption of the meaning of the sentence.
b) Students of art history are the group perceiving the academic rigor applied by the author of the book; their use of academic rigor is not the focus of this sentence.
c) CORRECT - The sentence suggests that art history students may accuse the author of the passage of insufficient academic rigor for failing to challenge the customary list of Baroque characteristics. It can be reasonably concluded, then, that sufficient academic rigor would include a challenge to this received knowledge.
d) Entertaining in the passage is used as a verb, not as an adjective as it is in this answer choice.
e) While the author of the passage might agree with this in a different context, the meaning of academic rigor in this passage is more specific.
