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

Solution: E

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).

https://well.blogs.nytimes.com/2013/04/26/ask-well-do-we-need-to-stretch/

Some have had young, healthy volunteers stretch for 20 minutes or more, others for 5 minutes or less. Still others have used older, stiffer volunteers or people with existing injuries. Not surprisingly, the results have been inconsistent. Even within the same study, people respond quite differently to stretching, with some showing increased flexibility and others not.

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.

"did not" is incorrect because it is not congruent with "showing", which is a continuous verb form (even if used as a participle here). "Did not" illogically refers to "responded". On this basis we eliminate A, B, and C.

d)some showing an increase in flexibility, while others not.
"Increase in flexibility" is not the same as the original "increased flexibility".
(I am not sure if "with" is needed here as you claim. I would not regard it incorrect. Please explain.)
This AC does not sound idiomatically.
e)with some showing increased flexibility and others not.
Succinct.

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 ...

I got E... but it was really tough.

I eliminated A and D for the same reason you did.

I then eliminated B and C because an ING form + and =/ did.
(others did not showing ... doesn't make sense... however simply having "others not showing" works)

I think the contrast is nice but not necessary.

I do not know whether i am correct or not but i feel that .......
The underlined portion is a modifier modifying the verb "reponded", hence a preposition phrase or clause must be used...hence B,C and E remains...."did " is past form but showing is not a past form, hence eliminate B and C
E is the best answer

I eliminated a,b and c, because others did not is incorrect.

D is wrong because an increase in flexibility and others not are not parallel.

Can anyone explain about below:
1. Why with is required here ? Will it be wrong if we don't use with?
2. difference between and and while to show contrast.

Hi guys,

I think use of with is not even an issue!

1)clearly "show+ing" increased flexibility & "did not show" are not parallel.
thus we can eliminate the options with "did".

2)D & E are left with us, we cannot eliminate them on the basis of "with".

here I think, there is a small & subtle difference=> "People" is the subject, thus people can show "Flexibility" either increased or decreased or little etc but people cannot show "an increase", this can be shown by a study or a survey or a result.

then, E it is!!!

this is how I interpreted it, please correct me if I am wrong!!

Cheerz!

Hi Archit,

I think the underlined portion modifies "people" and not responded.

pls correct me, cuz its contradicting the "ING" form's convention!

I think it's "B". Since it's a verb modifier, the modfier does not have to touch the verb, and "while" creates the required contrast.

Hi
I think the option is D because it is very straight short and simple i understand hope you all also agree that when a word is starting with a vowel for eg apple or elephant, we say an apple or an elephant not just apple or elephant similarliy in option D has we have "an increase" hence it is correct

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.

Hi vibhav

I'm happy to share.

Coordinating conjunctions join equals to one another (words to words / phrases to phrases / clauses to clauses)
For example:
* words to words: I love both POP and Rock music.
* phrases to phrases: Volcanoes are usually be observed near Hawaiian islands or Japanese islands volcanic arc.
* clauses to clauses: What you think and what you do are different.

Subordinating conjunctions join two clauses together, they make one clause dependent (or "subordinate") upon the other.
For example:
I was eating pizza, while my mother was eating noodle.

In short, coordinating conjunctions (FANBOYS) are more flexible than subordinating conjunctions.

Hope it helps a bit.

a)some showing increased flexibility, while others did not (showing increased flexibility) --- Not parallel and awkward

b)with some showing increased flexibility, while others did not (showing increased flexibility) --- Not parallel and awkward

c) with some showing an increase in flexibility and others did not (showing increased flexibility) --- Not parallel and awkward

d)some showing an increase in flexibility, while others not. (showing an increase in flexibility) > this correct but meaning changed

>Intended meaning --- some people have shown increased flexibility { Let's say flexibility increased by 50%) and others haven't

>Distorted meaning in option "D" --- some people are showing an increase {ongoing} but this is not the intended meaning

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

I think we are entirely talking about a meaning and parallelism problem here. My logic in general:
(1) You cannot use the structure "some showing...others did not" as it is not parallel. Further, "showing" plays a slightly different role vs. what a verb would normally have. So IMO, you canno refer to the same action with any form of "do" after it. => (A), (B) and (C) are out.
(2) Additionally, in all the options without "with" you are basically left with a very complex sentence, in which the last part lacks a verb. I would therefore prefer answer choices that have "with" so that the logical connection between the two parts of the sentence is clearer. => (D) is out and we are left with (E).

The only thing that still worries me a bit is the comma before the underlined part.

Can you elaborate bit more why E is better.
