OFFICIAL EXPLANATION
The longer fossil fuels are used to run transport vehicles, the more damage the earth’s ecosystem will suffer, with resources being exhausted to such a large degree that it will be difficult to restore them.(A) the more damage the earth’s ecosystem will suffer, with resources being exhausted to such a large degree
This answer choice is stylistically flawed. The phrase to such a large degree is wordy and redundant. Look for a more concise answer choice.
What helps us identify this question as a Redundancy question as well as identify this mistake is the following Stop Sign: to such a large degree / to a large enough degree(B) the more damage the ecosystem of the earth will be made to suffer, with resources being so exhausted
Although this answer choice corrects the Redundancy in the original sentence by replacing to such a large degree with so, it is not the most concise answer choice. The phrase the more damage the ecosystem of the earth will be made to suffer is wordy and redundant.(C) earth’s ecosystem will suffer further damage, with resources being so exhausted
Although this answer choice corrects the Redundancy in the original sentence by replacing to such a large degree with so, it is grammatically incorrect. This question uses a Double Comparative. The second part of a Double Comparative must begin with the word the. In this answer choice, however, it begins with the word earth's.
The structure of a Double Comparative should be: the + comparison..., the + comparison....
Example: The more he eats, the fuller he will be.
The faster he is, the greater his chance of winning.
(D) more damage the ecosystem of the earth will suffer, with resources being so exhausted
Although this answer choice corrects the Redundancy in the original sentence by replacing to such a large degree with so, it is grammatically incorrect. This question uses a Double Comparative. The second part of a Double Comparative must begin with the word the. In this answer choice, however, it begins with the word more.
The structure of a Double Comparative should be: the + comparison..., the + comparison....
Example: The more he eats, the fuller he will be.
The faster he is, the greater his chance of winning.
(E) the more damage the earth’s ecosystem will suffer, with resources becoming so exhausted
The phrase to such a large degree is wordy and redundant. This answer choice corrects the Redundancy by replacing the phrase with so. It also correctly begins the second part of a Double Comparative with the.
