I think I like E

"tested that" is incorrect IMO... tested that it could propel or tested that it could help??? unclear

b/w C D and E

C is a mess... able to propel or helping; D also isn't parallel: could propel or helping

A looks fine to me. In E i think 'capability' is not needed.

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

1. GMAT always thinks "have the capability to" and "could/can" are redudant. Please refer to og10th sc#87:

87. Beyond the immediate cash flow crisis that the museum faces, its survival depends on if it can broaden its membership and leave its cramped quarters for a site where it can store and exhibit its more than 12,000 artifacts.

(A) if it can broaden its membership and leave

(B) whether it can broaden its membership and leave

(C) whether or not it has the capability to broaden its membership and can leave

(D) its ability for broadening its membership and leaving

(E) the ability for it to broaden its membership and leave

Choice C uses whether or not where only whether is needed, includes the awkward and wordy construction has the capability to,

2. the correct idiom should be "have the capability of doing"

are you saying E is not OA? I agree that it's not the best, but by POE I didn't like any other choice (Idioms are my nemesis, so E didn't look wrong for "of" part)

A would be my 2nd choice... I don't think B is parallel

Would go with A too....

In "C" and "E" "to propel" and "helping"/"help" are not parallel

A does maintain that

B is surely out as we need a singular("engine" is the subject here)

Will go with A.

I think A is more || than E. Also E is wordy.

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

E - not ||
tested, and it could eventually have the capability to propel aircraft anywhere in the world within two hours or help

Guys, I agree with A.

But I cannot clearly understand the sentence structure.
Anyone can help?

"that" in the sentence is used as pronoun or relative pronoun?

I would choose A but have a question here

Is tested that correct.... the part after that seems to refer to the new engine and not it's testing....

There is a similar question in GMAT PREP (can't rem it)

something that humans....

U2 I think E is also having the ambiguous "it". "it" can refer to reasearch and development or jet engine.

So I think this should be A.

I think A is better one than E.

E is more wordy. As said in the previous posts, usage like capable or could all seems to me redundant

So I think this should be A.

PS Boss - I don't think "it" in E can refer to "research and development" because they are a compound subject.. what do you think?

Is it (E).
(A) seems to indicate that the jet engines will keep running until they "eventually" propel an aircraft within 2 hours

Precisely, and this is why I think the OA should be (A)

What`s the source of this question?

Is "that" correct in A?

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