我选A，从意思上理解，AD都没有错，但是按照Gmat的要求，要做到concisions，A更加符合，且读起来更像是G的语感。

I'm going to push you to do a little of the work here. Notice that we have the word "unlike" starting the sentence. Unlike is used to compare two nouns. What are the nouns compared using answer choice A, and what are the nouns compared using answer choice D?
[size=14.007px]Choice A compares the noun "innovative study." "that" stands for the innovative study.
[size=14.007px]Choice D compares "earlier works" and "innovative study"
