Idiom - 'made possible by [something]' and never 'made possible because...' ---> eliminates A, D and E

Essentially, the statement is saying, "field of physical cosmology is made possible by Einstein's theory of relativity; field of physical cosmology is made possible by the better ability to observe [farther]...'. So, for concision's sake, we say 'made possible by both [X] and [Y]'.
This can also be rewritten as 'Both [X] and [Y] made [Z] possible' ---> hence, B is correct.

+1 B

Split between "Because of", "by", and "as a result" --> demands a "by"
two parallel causes require a "both". Thus, "B"

The term "because of" represents the reason for an action.

Precisely because of the above reason - made possible 'because of ' seems correct.

Please any one clear the ambiguity here. As i am clear about one thing, 'because of' is used to represent the reason for an action.

IDIOM: It was made possible BY. So either B or C. In C, and also is redundant.

1) made possible because of - Wrong idiom; Correct idiom is - made possible by someone/something; So A, D, E are out.
2) Between B and C, in C, in 'and also', also after and is redundant.

Shouldn't 'and' also be highlighted in the question? it was really confusing at first since the highlighted area doesn't include and, yet it was mentioned in all solutions. At first I was crossing out options because they were repeating and.

Imo B

Its has a structure Both x and Y a closed parallel , hence we should be looking for answer choices that contain parallel structure .
B does that better than any other option.

Are we concerned at all about "because of... the better"? The awkwardness of that really threw me off. Also, isn't "both Einstein's theory" and "the better ability" lacking in parallelism?

(A) because of both Einstein's theory of relativity and

(B) by both Einstein's theory of relativity and

(C) by Einstein's theory of relativity and also

(D) because of Einstein's theory of relativity and also

(E) as a result of both Einstein's theory of relativity and

OFFICIAL EXPLANATION

The underlined portion of the sentence introduces two idioms: made possible by and both X and Y. The former idiom is incorrectly presented in the sentence as made possible because of.

(A) The choice is incorrect as it repeats the original sentence.

(B) CORRECT. This choice uses both idioms correctly: made possible by and both X and Y.

(C) This choice corrects the first idiom (made possible by) but introduces a new error by removing both and replacing it with and also, which is redundant.

(D) This choice repeats the original idiom error made possible because of. It also introduces a new error by removing both and replacing it with and also, which is redundant.

(E) This choice presents the incorrect idiom (made possible as a result of) rather than the correct idiom, made possible by.
