IMO A.

A. tested that could eventually propel aircraft anywhere in the world within two hours or help -correct. "that could propel" and "(that could) help" are parallel. Not here that could is understood, and may not need a repetition in the sentence.
B. tested that could eventually have the capability of propelling aircraft anywhere in the world within two hours or to help -use of "capability" with "could / can " is redundant
C. tested, eventually able to propel aircraft anywhere in the world within two hours, or helping -"to propel" and "helping" are not parallel
D. tested, and it eventually could propel aircraft anywhere in the world within two hours or helping -"could propel" and "helping" are not parallel
E. tested, and it could eventually have the capability to propel aircraft anywhere in the world within two hours or help -use of "capability" with "could / can" is redundant

D and E - it could refer to either research and dev. or jet engine

C - tested, helping are all incorrect. that is needed after tested

B - capability of propelling - to help are not parallel

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

Frankly speaking, this is a tricky question that got me stuck on A or E. I finally decided to choose E because of the verb meaning principle which is correctly employed in E as opposed to A. A sounds very attractive, grammmatically correct and is less wordier than E but the there is a subtle difference in the meaning of the verb as it doesn't make sense. A refers to the testing of the jet engine that could propel the aircraft anywhere in the world. Rather its the capability of the jet engine that could propel the aircraft anywhere in the world.

A. tested that could eventually propel aircraft anywhere in the world within two hours or help OK - Initial reaction was that this was wrong. But, I see how GMAT wants subject and verb to be close together only if there is a restrictive clause. Perhaps we can count one this for concision.

B. tested that could eventually have the capability of propelling aircraft anywhere in the world within two hours or to helpWrong - "could have" and "to help are not parallel

C. tested, eventually able to propel aircraft anywhere in the world within two hours, or helping Wrong - "Able to" is wordy. "Able to propel" and "helping" are not parallel. The phrase that begins with "able" was converted in to an adverbial phrase, thereby changing the meaning of the sentence altogether.

D. tested, and it eventually could propel aircraft anywhere in the world within two hours or helping Wrong - "Helping" violates parallelism, making the sentence nonsensical. Splitting the sentence into two different clause creates a different meaning.

E. tested, and it could eventually have the capability to propel aircraft anywhere in the world within two hours or help Wrong - The sentence is split into two different clauses, thereby making the sentence wordy.

IMO A

Answer A is perfect. please find the attached image ... for verification.

http://i.imgur.com/xUr3hAk.jpg

A is correct because that can modify the closest noun which is jet engine as tested is verb here. also in E could and capability of is redundant.

I hope this makes everything clear.

I think I deserve kudos if this is helping you :)

Yes, and adding to this, that is actually very flexible and can also modify the noun that is not nearest to that. For example, in the sentence below:

Marconi conceived of the radio as a tool for private conversation that could substitute for the telephone; instead, it has become precisely the opposite, a tool for communicating with a large, public audience.

While conversation is the nearest noun, that actually modifies tool here.

p.s. Our book SC Nirvana discusses this topic of what that modifies, in significant detail. If you can PM you email, I can send you the corresponding section.

This one is confirmed-gmat-prep problem.

As we know that if modifier is quite long (as Ron says 6 miles long) then we can place verb before modifier to keep verb close to the subject. Definitely all other choice are either awkward or wordy and even I felt that no choice is correct, but now A makes sense after reading discussion on mgmat forum.

the box of nails,that is on the counter, is to be used on this project.

its a correct sentence as 'is' represents singular noun which can only be a box here..

A very minor thing is that if this sentence were to appear on GMAT, you would expect that there is no comma before that.

This is because that is (what is called as) essential modifier and so, is not preceded by a comma.

On the other hand, which is (what is called as) non-essential modifier and is always preceded by a comma.

Having said that, for the most part, punctuation per-se is not explicitly tested on GMAT.

The OA was (A), but I chose (E) because the engine may eventually have the ability to propel, not eventually propel (as option (A) suggests). I also agree with the explanation that shekharvineet gave! Thoughts?

"Can" and "have the capability" are redundant.

I can do so... correct.
I have the capability to do so...... correct
I can have the capability to do so.... redundant.

Therefore E is wrong ("could" here is the hypothetical case of "can").

No need to strain much to reach the goal in a good number of the cases, if we can spot the easily visible and simple errors in a sentence.
'1. Have the capability has never been the correct selection in GMAT. Add to that the redundancy of 'could', and it becomes a popping error. Drop B and E reflexively
2.if there is going to be participle after the fanboys 'or' in the second arm, there should be a correspondingly parallel participle in the first arm. if not, it is a foul on symmetrical parallelism. One can make bold to eliminate C and D on this count.
A is left.

a new type of jet engine is being tested that could eventually propel aircraft

In the above underlined statement that cannot refer to "a new type of jet engine" because
"that" is placed after the verb "is being".

IMO , A is wrong , E is fine

Hi rkandula, this is an official question and the official answer is A.

So, this just shows how flexible that is, in terms of what that can modify, even a noun before the verb.
