Solution

Sentence Analysis

The sentence says:

The pilot JC had 17 official speed records by 1940. She earned these records at a time when aviation was so new that many of the planes she flew were dangerous to fly.

The sentence has one error: "aviation was still so new for many of the planes she flew" communicates that aviation was new for the planes!! Logically, it seems we want to use ?so X that Y" idiom.

Option Analysis

(A) Incorrect . For the reason mentioned above.

(B) Incorrect . For the following reasons:

  1. Repeats the meaning and idiomatic error of the original sentence.
  2. ?for?, a preposition, is followed by a clause "many of the planes were_". A preposition can never be followed by a clause.

(C) Incorrect . For the following reasons:

  1. ?where? refers to a place, not ?time?. Therefore, its use is incorrect.
  2. The use of demonstrative pronoun ?these? without a noun following it is not recommended. The demonstrative pronouns ?this? and ?these? need to be followed by a noun e.g. this idea, these records etc.

(D) Incorrect . For the following reasons:

  1. The structure ?so new such that? is incorrect. It should be ?so new that_".
  2. Given the context of the sentence, the correct word for ?time? is ?when?, not ?in which?. (OG explanation says so and I agree)

(E) Correct . ?earned? acts as a verb-ed modifier correctly modifying ?records?. Everything is fine with this option.
