Parallelism + Idioms are the sorts of concepts that need to be verified.

Option A: Incorrect
The statement in option A is not idiomatic. The phrase “as” is missing after “was” in the first half of the sentence. The statement would be “ the invention of anesthesia was (as) essential ….as the invention of the propeller was to powered flight”. There option A is incorrect as it includes a grammatical error within it.

Option B: Incorrect
Option B does not maintain parallelism. The statement used the word “inventing” first as a verb and then it is used as a noun (invention). The statement follows “ inventing anesthesia was as essential for the development of surgery as the invention of the propeller was for powered flight.” Therefore, the statement needs to be parallel and had to use the word “invention” as a noun (invention) in both cases. Option B thereby gets eliminated.

Option C: Incorrect
Option C is not idiomatic. The statement structure “ the invention …. was as essential…. much as the invention….” does not follow the idiomatic pattern. Therefore, option C goes out of scope.

Option D: Correct

Option D follows the adjustment of the given phrase. The statement states “ the invention … as essential …as the invention…”. Therefore the statement in option D is parallel and idiomatic. Thus it is the correct answer.

Option E: Incorrect
Option E follows the statementthe invention of anesthesia was essential…, so was the invention of the propeller….”. The statement does not maintain the idiomatic pattern and it is a little bit wordy. Therefore, option E is incorrect and thereby gets eliminated.
