E is simply awkward and wordy IMO

Compare the two sentences - (2) is concise and clear and conveys the same meaning as (1)

it could eventually have the capability to propel --- (1)

that could eventually propel --- (2)

I can not tell you official answers for all my questions.
Just I can inform you the answers what I've got. =)

My choice for this question was A. HOWEVER,
my answer sheet says it's E...............

IMO, the problem of A is,
"being tested that could"
Where's subject of could? If a type of jet is subject for could, isn't this sentence adequate in terms of grammar?

You answered my explanation. "that" should follow a noun.
though E is wordy, it does not have grammatical error.

Oh I see.. wow.. missed it.

Well, jet engine is not the subject but the subject is TYPE [of jet engine]. Remember "of jet engine" is a prepositional phrase modifying TYPE - Subjects are never included within prepositonal phrases.. they just serve as adjectives.

Given that "TYPE" by itself can't propel - we need "something" that can.. Hence E.

Not sure if you all concur with the above - but this is certainly a tricky question and that's the way I would look at it if I had to explain E.

Could anybody elaborate on whether "it" in E is correct?

I always have problems with pronouns, and I (for example: this "I" is needed?) dont know when do they need to be repeated and when not.
