I think its E, because it sounds the most parallel. However sentence correction is my Achilles heel....

I was between B & E but go with E because B's 'to be....and even as' doesn't seem right....

the question is about gas hydrates potential as A, as B and as C. the best construction is the parallel construction choice E.

Yes. It should be E. But OA given says "A" which, I believe, doesn't make sense at all!

I chose "A."

I see your decision to go with "E," based on parellism, but first that parallelism has to be idiomatic: "...being studied for their potential as...". When you put it back in the sentence, "potential as" does not sound as good as "potential to be." Instead, "A" correctly uses the idiom, "...being studied for their potential to be...". It also has correct parallelism, "...to be [blank]...and [blank]". If you take out the modifier, "possibly...instability," it makes more sense. The modifier is there to throw you off.

Despite the above reasons, it cannot be "B" because adding "even" in there is unnecessary. Just plug the answer choice back in the stem to make sure it flows.

Although the idiom is 'potential to' but E makes more sense in this case because of ||ism.
In A it is not clear what 'possibly causing' refers to reservoirs or gas hydrates.

Potential to be ~ / as ~ both seem ok. // Structure.
E seems to be the best choice.

Correct idiom is "for x to be y", and choice B isnt parallel, thus A.

Any one can confirm this idiom? I searched up and right and couldn't find it though. But I think it is the correct way of using it.

I think "potential to do something", not for x to be y

I go with A ....
however my reasoning is slightly different ..
I reckon potential as is not the correct idiom ..
e.g X has the potential to score 750.
hence I narrowed down to A or B ....
In B , there is no need for even as

I have never seen "potential as"
potential to is correct.

A is parallel.

I found the below article from which the sentence is extracted and the article itself is written with option E.

can someone explain what is the correct option...A or E?

Hey All,

I get asked by PM to take this one on, so here I am. How goes it?

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.

This question is about parallelism versus modifiers. We don't really want any modifiers here, so we have to get rid of answer choices that try to spin it that way.

A. to be huge reservoirs of energy, possibly causing sea floor instability, and
PROBLEM: Commas set off lists or modifiers. If it's a list, it's already unparallel (to be huge, causing, significant are not parallel). Modifier doesn't make sense either, however, as "causing" would be modifying the previous clauses. The fact that the hydrates may be reservoirs of energy is not causing sea floor instability, so that's out.

B. to be huge reservoirs of energy, possibly causing sea floor instability, and even as
PROBLEM: Same as above on every level.

C. as huge reservoirs of energy, possibly causing sea floor instability, and
PROBLEM: Same as above.

D. as huge reservoirs of energy, and the possible cause of sea floor instability,
PROBLEM: You only use COMMA followed by "and" at the end of a list of more than three things, not just two. Also, now the final section has become an appositive modifier. This is because the list MUST have ended after the "and", so the comma must be setting off a modifier. Because it's just a noun at the end, it could only be a noun modifying a noun ("Thomas Jefferson, our nation's third president, was awesome."). Obviously, the "instability" is not a "significant contributor to global warming"

E. as huge reservoirs of energy, as possible causes of sea floor instability, and even as
ANSWER: Look at the lovely parallelism "as, as, as", plus it finally makes sense!

Hope that helps!

Tommy
Sorry I have to disagree. PROBLEM: You only use COMMA followed by "and" at the end of a list of more than three things, not just two. -----> D is wrong since the list has to be similar.
"huge reservoirs" is plural, so other items in the list have to be plural (technically)

D. as huge reservoirs of energy, and the possible cause of sea floor instability, ---> should be "causes" not "cause"

Pls correct me, if I'm wrong.
