### HideShow timer Statistics

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
B. tested that could eventually have the capability of propelling aircraft anywhere in the world within two hours or to help
C. tested, eventually able to propel aircraft anywhere in the world within two hours, or helping
D. tested, and it eventually could propel aircraft anywhere in the world within two hours or helping
E. tested, and it could eventually have the capability to propel aircraft anywhere in the world within two hours or help

I was told that the correct answer is A, but I think E is correct. I think that the relative pronoun in A is wrong.
Would anyone explain what is the correct answer?

IMO A

In E, 'could' and 'have the capability to' I think create redundancy.

The word "that" refers directly to the new jet engine. The meaning is clear.

sudeep's reasoning sounds right. Also, "capability to" might be wrong? I'm not sure, but when someone says, "I am capable of learning," the correct idiom is "capable of." I'm not sure if "capability of propelling" would have been correct, but it's just a thought.

I'd go with A.

I think E is too wordy and "have the capability" slightly alters the meaning of the sentence.

A 'that' can't refer to anything else other than 'jet engine'
