Guys, the OE says: ' Explanation: In this type of sentence correction problem you need to focus on parallelism and verb form. At the end of the sentence, if you say “did not” you should ask “did not” what? The general rule is that there needs to be a verb that is being replaced by “did”. In this example, there isn’t a verb, just a participle, so the structure would not be parallel: You cannot say “some showing this, while others did not show this” or “some showing this and others did not show this” As a result, (A), (B), and (C) are all incorrect. In (D), you would need a complete clause after while with a comma and all you have is “while others not showing” Only (E) creates a parallel structure with two participles following nouns after the preposition “with” (the second participle is understood): “with some showing this and others not showing this” Answer is (E). '

Any idea whats the logic of while and comma need a clause?

Hi vibhav.

In this question, WHILE is "subordinating conjunction". Subordinating conjunctions join two clauses together. Thus, if you use "while", two clauses are required to make a sentence grammatical. Otherwise, you should use "coordinating conjunction" (and, but, so, yet, for...). Thus E is better than D, and is correct.

Hope it's clear.

Can you elaborate bit more why E is better.

Even within the same study, people responded quite differently to acupuncture, some showing an increase in flexibility, while others not [showing increase in flexibility]

It has clause on both side, isn't it ?

Please note that the ones you pointed out are NOT clauses but phrases.

A clause should contain a" working" verb and a subject.
Do not mistake the -ing form of verb for a "working" verb.

Here showing is used as an adjective , that is, a modifier - giving extra info. about some and others...

A clause would look like the following-

some showed an increased in flexibility , while others did not ( show ).

Here, showed is past form of the verb show. BUT such usage in the above sentence would require a conjunction before some.

Hope the above helps.

I donot mind Kudos.. :-D

I believe that "some" is making the sentence bit vague as not sure if it is referring to people or acupuncture. So I believe "with" is logical and correct construction here.
E is correct as with "While" you need a full [noun] + [verb] construction which is clearly not there in any of the other option.
(p.S.) with option E there should be no "," in question stem.

1. We eliminate all those options which do not have 'with' - Thus, options A and D are eliminated.
2. We eliminate al those options which have 'did not' as it is not parallel to 'with some showing' - Options B and C are eliminated.

What remains is E and hence is the right Answer. Even if we do not use the elimination technique, we can see that E is the only option which gives grammatically and logically parallel entities.

Easy to check for parallelism.

a)some showing increased flexibility ( PHRASE), while (PARALLEL MARKER) others did not.(CLAUSE)

b)with some showing increased flexibility,(PHRASE) while (PARALLEL MARKER) others did not.(CLAUSE)

c) with some showing an increase in flexibility (PHRASE) and (PARALLEL MARKER)others did not.(CLAUSE)

d)some showing an increase in flexibility (PHRASE), while (PARALLEL MARKER) others not.(PHRASE)

We expect a complete clause after while but even that will not make it parallel.Incorrect use of while in D makes it wrong.

e)with some showing increased flexibility(PHRASE) and(PARALLEL MARKER) others not.(PHRASE)

So,E is preferable.

The group of words after "While" is not a clause - Clause requires sub and verb. "Showing" is not a verb as it is not preceded by is, am,are etc.

B) with some showing increased flexibility, while others did not.

E) with some showing increased flexibility and others not.

Hi,
Since there is no verb in the first phrase before , 'did not' doesn't refer to a verb , making the construction nonparallel . 'while' is used to join clauses whereas modifier before comma is a phrase. Therefore, to maintain parallelism we need a phrase after 'and'.

A) some showing increased flexibility, while others did not.
B) with some showing increased flexibility, while others did not.
C) with some showing an increase in flexibility and others did not.
D) some showing an increase in flexibility, while others not.
E) with some showing increased flexibility and others not.

Can anyone please explain the use of "with" in SC?

"With" is used to introduce a prepositional phrase modifier.Prepositional phrase modifiers can be used in 2 ways:
1. Noun modifier: Chicken with rice is my favorite food.
2. Verb modifier: I cannot repair this table, at least with this tool.

A,B and C are easy to eliminate. Why is choice E preferred over D?? Both seem very similar

From the above explanations, "increased flexibility" seems to be preferred over "increase in flexibility". I don't understand why?

Hi Prateek176!

Happy to help

You're right that they are very similar!

The problem with D is not "increase in flexibility", it is "while". "While" is a subordinating conjunction, so it needs to be followed by a clause (subject + verb). Here, we have "while others not", which is not a complete clause, since there is no verb. If we don't have a complete clause, then we need to use a coordinating conjunction ("and", "but", "yet", "for", "so"...) instead. Since E uses "and", which is a coordinating conjunction and so does not need to be followed by a clause, it is correct

Hope that helps!

D) some showing an increase in flexibility, while others not.

There is an issue with "increase in flexibility" in D.

"some" is plural".

"an increase in flexibility" is singular.

So, if read literally, D conveys that multiple people, "some", showed ONE increase in flexibility, as if a bunch of people shared this one increase in flexibility.

To make sense, D would have to use the plural "increases" and say, "some showing increases in flexibility".

E) with some showing increased flexibility and others not.

In E, this issue is avoided, as "increased flexibility" is not countable. So, there is no plural version, and thus, "increased flexibility" is fine with "some".

Also, the meaning conveyed by "increased flexibility" is probably a bit more appropriate than the meaning conveyed by "an increase in flexibility". I doubt that the speaker means to convey that some people showed "an increase", in other words, "one increase", in flexibility. Probably the point is that with acupuncture, maybe multiple treatments, people showed "increased flexibility".

a)some showing increased flexibility, while others did not.

b)with some showing increased flexibility, while others did not.

c) with some showing an increase in flexibility and others did not.

d)some showing an increase in flexibility, while others not.

e)with some showing increased flexibility and others not.

With is required in the answer choice, so A D are removed.
While is required for contrast, so i removed C E out of the remaining and was left with B as the answer choice
IMO the answer should be B

Can you please post the OE and the source of the problem ...

Thanks MartyMurray for clarifying the precise reason of difference b\w last two answer choices.
The actual problem is NOT the usage of "with" or "and/while", but the subject-verb agreement.

Even within the same study, people responded quite differently to acupuncture, some showing increased flexibility, while others did not.

(A) some showing increased flexibility, while others did not

(B) with some showing increased flexibility, while others did not

(C) with some showing an increase in flexibility and others did not

(D) some showing an increase in flexibility, while others not

(E) with some showing increased flexibility and others not

Imo E

This question is very tough. It test many concepts of grammar - namely comparison, parallelism and sentence structure

1) Note that even is present in the non underlined part of the sentence so we have to have contrast sentence and a full clause with its subject and verb will come.
2) Two entities in comparison must be parallel and should make sense.

A some showing increased flexibility, some showing increased flexibility, while others did not highlighted clause is not parallel as different verb forms are used. Second is a full clause with its subject and verb while "some showing increased flexibility" is not a full clause rather is noun modifier. So drop this choice.

B Same problem as A. Parallelism is not correct

C Parallelism is incorrect same as A

D This one is the most difficult to eliminate. while is a subordinating conjunction so a clause will be correct but we do not have a complete clause after while so drop this choice.

E is correct while is replaced by "and" and parallelism is proper

The problem as I see here is not with the use of the prepositional modifier ‘with”. Even an absolute modifier will be good enough and even may be better sometimes because of leanness. For example, the following versions are perfectly acceptable
A. Even within the same study, people responded quite differently to acupuncture, some showing increased flexibility, while others not.(not showing)
D. Even within the same study, people responded quite differently to acupuncture, some showing an increase in flexibility (generally good enough, but not in the given context), while others not.

But the problem with A is with grammar that we are trying to couple a participle with a working verb; this is not parallel. In the case of D, there is distortion of meaning. Increased flexibility is different from an increase in flexibility. An increase in flexibility in some cases may even be an on- going thing, whereas increased flexibility is something that may be already increased and not be increasing any more. This subtlety makes D infidel to the original intent of the text in question. So, A and D are out.

Till now I have learned that [With][noun][gerund] structure is not acceptable in GMAT, but here the correct answer has this structure. Would you able to throw some light on this?

Tamalmallick13 First, not all -ing words are gerunds. A gerund is an -ing word used as a noun, and "showing" is not a noun here. Rather, it's a present participle serving to modify "some." Using -ing words to modify nouns in this way is quite common:

I ran down the street, with my dog running behind me.
People living in glass houses shouldn't throw stones.
