C is the right answer. The important issue with those is that when we are construing a sentence we have to make sure apples are being compared to apples and oranges are being compared to oranges. In the original sentence the efficiency of cars is being comapred to "any time in their production ...

I think the Answer is D! A and B are out becuase it does not specifically refer to the levels. Does it refer to material level or mystical level? E the correct idiom is contact...through not contact....due to. Eliminate. Between C and D the correct idiom when discerning two options is the former or ...

E is wrong because the sentence is not conjoining gerunds which requires "the" to clarify the clause. The sentence is joining verbs therefore establsihing is correct and "the establsihing" breaks parallelism.

I think the Answer is D
A and B has an subject verb issue. makes v. make. The subject is plural therefore make is preferred. Eliminate A and B.
Both C and E have an ambiguous pronoun issue. Specifically who is "they" referring to? The people or the food? Therefore eliminate.
Pick D!

Definitely go with E myself. I think the first split comes between worry vs. worrying or worried. There are no indication in the sentence that the concern is in the past tense therefore eliminate C. The sentence indicates that concern is present therefore the simple present form of "worry"...

I think what you have to keep in mind foremost is not necessary if a certain choice changes the meaning. It is more of an issue whether the sentence makes logical sense. You can get a hang of this when you initially read the sentence. Here "or monitoring of population changes of as many as, or ...
