Hi ESB! Happy to help you out with why answer choice (E) is incorrect
The correct answer choice will explain something that the author would disagree with based on the passage. However, the author would not necessarily disagree with answer choice (E).
In the first paragraph of the passage, the author explains how sometimes painting exhibitions are chosen based on the artist who created the paintings exhibited (such as an exhibit of only paintings by Rembrandt). However, the author does not comment on whether or not he disagrees with this approach for displaying paintings—all we know from the passage is that the author believes that we should not curate a display of early, nonfiction films based on the creator or studio behind the film (which he explains in the second paragraph).
Because we only know that the author disagrees with this method of "collecting the similar" in the context of early, nonfiction films, we do not know that the author would deny that art exhibitions should
sometimes use this method. From the information given in the passage, for example, it is possible that the author believes that painting exhibitions should be based around one particular artist. Since we do not know whether the author thinks there are situations in which collecting works all by the same artist for an exhibition is appropriate, we cannot know whether the author would definitely disagree with the principle stated in answer choice (E).
On the other hand, answer choice (B) describes a principle that the author would definitely disagree with, since the approach advocated for in the second paragraph is the exact opposite of this principle.
I hope this helps!
