I'm having a question about a minor detail regarding the correct answer choice: (B).
I feel that the word "only" in choice (B) distorts the main point to have a degree issue. The author presents her main point in lines 30-34 beginning with "But the..." However, can we really deduce that the author feels that the works can only have anticipated new directions in artistic perception and expression? I am having a hard time justifying this.
Of course, since this is a choice that "most accurately" states the main idea, I eliminated the other choices on the following basis:
(A): Too narrow and the "common desire" part is unsupported.
(C): Opposite answer.
(D): "Incapable" is contrary to author's view that it CAN potentially express a vision.
(E): The reasoning that it was "impossible to predict" is unsupported.
