A中的could是can的过去时态.时态不对吧.请指正.

本题A虽然读起来不爽，但是没有致命错误，个人意见：

After more than four decades of research and development, a new type of jet engine is being tested that could eventually propel aircraft anywhere in the world within two hours or help boost cargoes into space at significantly lower costs than current methods permit.其中的is being tested是倒装，因为that从句的修饰部分太长了，所以is being tested提前了。

E的致命错误除了could和have ability重复之外，capability的用法是，capability of doing，没有to do的用法，这个是肯定了，相信所有的语法书里都是一样的。

所以，E绝对不能是答案。

我觉得E对,因为A中that引导的是非限制性定语从句,也就是去掉后句意依旧完整,而非限制性定语从句一来不能用that引导,二来需要用逗号与主句隔开,那A就不对了

我坚决支持michellechang的意见，我觉得Ｅ不对，如果选Ｅ，这句话it could eventually have the capability to怎么解释呢，是重复，还是把原句的ｃａｎ（表能够）改变成表示可能的意思，无论是那种都是不对的。而且tianwan说的也对，ｈｅｌｐ和谁平行啊？

After more than four decades of research and development, a new type of jet engine is being tested that could eventually propel aircraft anywhere in the world within two hours or help boost cargoes into space at significantly lower costs than current methods permit.

A.
            tested that could eventually propel aircraft anywhere in the world within two hours or help

E.
            tested, and it could eventually have the capability to propel aircraft anywhere in the world within two hours or help

个人认为应该是E。A里面的that说不通，既不是定语从句（与修饰的东西隔得太远）也不是先行词，（因为没有主语）。所以句子读起来总觉得缺了什么。E 罗嗦了点，但是语法没有问题，句意也算有理。这里的could和capability不是同一个意思，应该不是句意重复。

赞同A，是定语从句后置修饰，E中can和capability明显重复

A正确。正式的英文中，为了避免句子的头重脚轻，经常把主语的定语置后，保持句子的平衡。
