Dear Friends,

I was having problems in answering the following question.

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 help.

OA after some discussions.

IMO E

A) not parallel: to be smth, doing smth and smth. it should be " to be smth, smth and smth"
B) out, because not parallel: "to be" and "as";
C) not parallel: one more "as" should be used after the last "and" just to maintain parallelism;
D) as in C, in D "as" is lacking;
E) i think this is the correct answer!

although i always use "potential" with "for", not with "as"!
I know of no more encouraging fact than the unquestionable ability of a man to elevate his life by conscious endeavor.

IMO E - A typical question to test parallelism and Option E is the only sentence with a parallel structure.

"Potential to" and "potential as" both are correct.

Potential to + verb

potential as + noun

Here "as" is correct as "huge reservoirs of energy" is a noun phrase. So we are left with C,D and E.

Only E maintains parallelism.

I hope this helps !!
