OA: D

I have specific questions:

1. Can we use "bot because"?
2. Besides the usage of both because, what is the main problem in C?



Firstly, GMAT prefers the subject to be at the beginning of the Sentence. Therefore you should look for sentence that does exactly that. That leaves us D and E. E is wrong because which at the end of the sentence modifies Dollar.

C uses It, which does not have a clear referent. Also, it completely destroys the parallelism. Ideally moment you spot a list check the answer choices that maintain parallelism, it will help you eliminate the wrong answer choices.

Another mistake people make is that when the idiom used is Both X and Y, sentence should only have 2 items. I.E. Both X,Y and Z is wrong. Its a trick used my Question framers.
