May i know which version of OG has this question , curious to see the official explanation :)

This seems to be a GMATPrep question and hence, no official explanation will be available.

In any case, official explanations are of some use for incorrect options.

Also, I do recollect coming across another question from a recent OG, where which was doing the same thing. Again, can't remember the exact question.

I totally agree, and I find that structure to be awkward and illogical. The following alternative structures are better.

After more than four decades of research and development, being tested is a new type of jet engine 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.

After more than four decades of research and development, a new type of jet engine 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 is being tested.

Regardless of whether one could debate that the structure is OK, GMAC should not have used such an illogical, awkward, unfamiliar, and debatably incorrect structure in an OA. The question should have been edited or thrown out.

Before seeing this question, I would always think that "that" refers to immediate noun.
In this question, noun, "the jet engine", is far away from that. Moreover, "A jet engine is being tested" is in passive voice.
So, this question doesn't seem like GMAT question.
I understood parallelism error. My doubt is that can GMAT put such question in which one error is corrected and other is ignored?

Please throw light on this doubt.

Please throw light on this doubt.


First, let's address the use of the passive voice.

In many cases the use of the passive voice is clearly sub optimal. When such sentences are presented in GMAT Sentence Correction questions, the correct answers to the questions will be ones that involve use of the active voice rather than use of the passive voice. However, while it is the case that in most cases, use of the active voice will result in a version better than one in which the passive voice is used, the use of the passive voice makes sense in some cases, and, therefore, it is not the case that one can always consider the use of the passive voice to be an error in a Sentence Correction question. Sometimes, the correct answer to a GMAT Sentence Correction question will involve the use of the passive voice.

So, the use of the passive voice in the OA to this question does not constitute an error.

Now let's address the separation of "that" from the noun to which it refers, which is "engine".

It is not entirely correct to say that a restrictive modifier always directly follows that noun that it modifies. Consider the following example:

The house near the center of town that Jim wanted to buy is no longer available.

In the above example, it is clear that Jim didn't want to buy the center of town or the town, he wanted to buy the house. However, the restrictive modifier, "that Jim wanted to buy" is separated from "house" by another modifier, "near the center of town".

This separation is fine, and a sentence structured in this way would be considered correct were it to appear in a Sentence Correction question. As a matter of fact, the entire structure, "house near the center of town", could be considered a noun, in which case, the restrictive modifier, "that Jim wanted to buy" would directly follow the noun that it modifies, "house near the center of town."

However, in the question posted in this thread, we don't have such a situation, we have a noun, "jet engine", followed by a verb, "is being tested", followed by a modifier, "that could eventually propel ..."

As I said in an earlier post, I find this structure to be illogical and awkward, one could only hope that you wouldn't see such a structure in any other practice question or in any question that you see on the GMAT. However, you might see it. In fact, here it is again in the OA to this question from the Official Guide, https://gmatclub.com/forum/gusty-wester ... 42543.html.

The story out there is that, when a sentence includes a relative clause modifier that is long, as is the modifier in the sentence in the question that is the topic of this thread, a verb in the sentence may correctly come between the modifier and the antecedent of the pronoun that appears at the beginning of the modifier, in order to make identifying the subject-verb relationship easy for a reader.

Therefore, while I personally still do not like this structure, and, while I find that including it in GMAT Sentence Correction questions does not make sense, you may want to keep it in mind on the off chance that you see it in a Sentence Correction question on the actual GMAT.

Firstly Can u please let me know the Subject Verb pairs in this sentence (choice A).
Also if the choice B had 'to propel ' instead of 'of propelling' would the sentence be correct. Please highlight the subject verb pairs for this sentence as well.

Thank you.

Here's (A) again:

Quote:
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.


The two verbs in red correspond to the subject in blue. ("That," technically the subject of the clause, refers to "jet engine.") So the jet engine could propel aircraft or help boost cargoes into space. Perfectly logical.

As for (B), sure, if we changed "of propelling" to "to propel" you'd address the parallel construction issue, but you'd still have two problems. First, "capability to propel" is not an ideal idiom, and second, the phrase "could eventually have the capability to propel" contains a redundancy, since the word "could" already implies a capability. (Notice that (A) leaves out "capability" altogether.) So the adjustment would make (B) less bad, but still an inferior alternative to (A).

I hope that helps!
