GWD29--41

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

答案是D,但我觉得明显不对,有人说答案是A,从to be 和as上区分? possibly causing sea floor instability,是修饰还是并列成分呢?

从并列结构上来说,我觉得E最合适了.

大家提点一下哈…

第二段刚开始

What they had were bits of gas hydrates--chemical compounds that are increasingly being studied for their potential as huge reservoirs of energy, as possible causes of sea floor instability, and even as significant contributors to global warming. Scientists had long speculated about them and even made them in the laboratory, but until now only a few had been seen in nature.

只要google一下什么都有了，很好很强大，我也找到那个出处了http://findarticles.com/p/articles/mi_m1134/is_n4_v106/ai_19493094/
就是应该选E
