OE

The correct response is (B). This choice correctly uses the present-tense verb “allows” which agrees with the present-tense verb “are.” Additionally, it correctly places a comma before “which.”

If you chose (A), we need a comma before the word “which” to set it apart as a clear modifying phrase. The past tense verb “allowed” does not agree with the present tense verb “are” in the non-underlined portion of the second independent clause.

If you chose (C), no comma here before "which" means this choice is incorrect. We’ve also got a past perfect verb (“has allowed”) that conflicts with present tense “are” in the non-underlined portion of this sentence.

If you chose (D), remember the word “that” is restrictive meaning it is necessary to the meaning of the phrase, while "which" is not restrictive. The word “which” adds a sort of parenthetical note to a sentence.

If you chose (E), “water allowing” is unclear. We are missing a relative pronoun or a comma between “water” and “allowing.”

B again, because it has a comma before the word which

I picked E as it is constant oxygenation that should cause rejuvenation not water as in B

Without comma which modifies water


B. by virtue of their constant re-oxygenation of the water, which allows them
Correct

C. on the grounds that their constant re-oxygenation of the water which has allowed them
Without comma which modifies water


D. since the constant re-oxygenation of the water that has been allowing them
It is not clear that the doer of re-oxygenation is Algae


E. by virtue of their constant re-oxygenation of the water allowing them
Without comma allowing modifies water

In my opinion the question is poorly designed.
In the OA B "which" modifies "water" and is not correct as it should refer to "the algae virtue".
So I marked E because I supposed that the author forgot the "," before allowing

The "which" refers to "re-oxygenation" and not to "algae virtue". Therefore, the question is designed correctly. "Which" doesn't always have to refer right to word it is next to, sometimes a modifier can be in between.
