Sentence Correction

Gas hydrates, chemical compounds of water and natural gas, are increasingly being studied for their potential to be huge reservoirs of energy, possibly causing sea floor instability, and significant contributors to global warming.

A. to be huge reservoirs of energy, possibly causing sea floor instability, and
B. to be huge reservoirs of energy, possibly causing sea floor instability, and even as
C. as huge reservoirs of energy, possibly causing sea floor instability, and
D. as huge reservoirs of energy, and the possible cause of sea floor instability,
E. as huge reservoirs of energy, as possible causes of sea floor instability, and even as

Please also explain your reasoning.

I think E is the Answer
E maintains parallelism

as huge || as possible cause || as significant

At last point, other options are not making sense.

on first look i would have marked E as the answer - for parallelism.
but according to manhattan sc guide - "potential to" is the correct idiom.

hence IMO B.


Thanks!

damn IDIOMS! aaaarrgghhhhh!

IMO E. What is the OA ?

Should be E.

Hi guys......i checked on many sites........

Both potential to be .......and potential as ....are correct..........

Verbal instructors please explain which one of the two should we use in this context....... and also pls explain the rest of the sentence.......

Any thoughts. IMO E coz of parallelism.

which idiom is correct

potential to be or

potential as

Potential to [verb], potential as [noun]. Both are correct idioms, given the verb "be" with "potential to" or the noun clause "huge source of energy" with "potential as"

Everything boils down to parallelism; (E) is the only answer choice where all three elements of the list are parallel "As huge sources....as possible causes...as significant contributors"

Hope that helps!

Hi Eli, thanks for clarifying the potential as/to idiom, but why have you choosed E which repeats as in three places the last being even as..

if potential as is common to all three activity : huge reservoirs of energy, possible causes of sea floor instability, and significant contributors to global warming.

Do not you think that repeat of as w/o potential is awkward to begin with and even as is making it even more awkward.

Hi Eli

I marked C here thinking the intended meaning of the sentence has a causation with "sea floor instability"-it must be retained. Your thoughts pls.
