Could you please comment on this one? I never try to learn any idiom and intsead try to go by the context and the meaning a particular phrase conveys.

On this one I chose E,
As a result of both X and Y , Z was made possible.

Why I discarded B- made possible by X and Y .here X and Y are non living things and hence I thought using "by" would convey that the action( making possible) was done by Einstein theory.

Please correct my understanding. Where did I go wrong? And is there a way to tackle this problem without looking at the idiom ?

Doesn't the article placement violate parallelism on 'B'?
Don't get me wrong, others have solid reasons for elimination, I just found it odd that B would keep the stray "the" or is that an acceptable practice?

'B' doesn't strictly follow Both X and Y; it follows Both X and the Y, which is usually a cause for concern on parallelism questions.

Am I missing something?

During the twentieth century, the study of the large-scale structure of the universe evolved from the theoretical to the practical; the field of physical cosmology was made possible because of both Einstein's theory of relativity and the better ability to observe extremely distant astronomical objects.

(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

"made possible by" would convey the intended meaning appropriately. So it's between B and C.
"by both X and Y" in B is better than "by X and also + Y (noun)" in C.
Hence, B.
