Explanation
Creating a filter: in this question, we can identify an
error in the original sentence by restoring an elided portion of the sentence;
an elided phrase, or elision, is a phrase which has been omitted but is clearly
understood. When a sentence contains an
elision, inserting the elided words will sometimes expose an error, especially
in the use of comparisons and pronouns. Namely, the sentence as written
says, "his symphonies are performed more than any other composer is performed."
Composers aren't performed. The intended meaning is that, "His symphonies are
performed more than those of any other composer...are performed."
Applying the filter: our expectation is satisfied in
choice (D). Choices (B) and (C) fail to solve the problem and still make us
talk about composers when we want to talk about their symphonies. (E) is proper
in making the comparison about symphonies, but "as" is incorrect. The sentence
using the comparative word "more," and both "more" and "less" require always
the word "than" and never "as." So (E) is out. The correct answer is (D).
