请教大家一道并列结构的题目，谢谢！

the development of a new jumbo rocket that is expected to carry the United State into its next phase of space exploration will be able to deliver a heavier load of insruments into orbit than the space shuffle and at a lower cost.

D> a newly developed jumbo rocket, which is expected to carry teh United States into its next phase of space exploration, will be able to deliver a heavier load of instruments into orbit than the space shuttle can. and at a lower cost.

E> a newly developed jumbo rocket, which is expected to carry teh United States into its next phase of space exploration, will be able to deliver a heavier load of instruments into orbit than the space shuttle can. and to cost less.

这个题目我最后徘徊在DE之间 不知道该选择哪一个。我最后选择的E，这个题目的主干结构为……rocket will be able to ……， and ……  所以我认为句尾的and 应该与be able to 后面的部分并列，但是答案是D，很不理解。 请NN帮忙！！谢谢！！

我觉得这个存在语意上的差别，E在语意上是不可能并列的，前面说的是能够传递什么东西，但是他不能是“能够花钱少”前后在内部联系上出现了不一致的现象，不能并列，反而D的感觉更好一些，不要一味地追求并列关系。LZ细细体会一下吧。（可能不对，但我是这么感觉的呵呵）

感觉D语义上比较合适，选择E就是觉得结构上更合理。谢谢你的意见！
