Review: Galileo's Attack


Explanation

Creating a filter: The prompt starts out well but runs into problems with "as well as," a phrase that is rarely well used. We check out the answer choices looking for better options.

Applying the filter: we find bigger defects; there are parallelism problems with the attacking and the expositing all over the place here. Choices (B) through (E) all fail to be parallel. Choice (E) looks close but the article "the" before "expositing" makes it a noun and ruins it. The correct answer is (A). We could defend the "as well as" the way it's written as needed to remove ambiguity and clarify that the Dialogue wasn't an attack on the exposition, but it doesn't matter, as long as we find objective grounds for our answer. The correct answer is (A).
