Even within the same study, people responded quite differently to

Hello experts,
A prompt question about answer choice B , I was wondering how is the proper way of doing the test of replacing the "did" , to see if the sentence makes sense.
"While others did not respond" OR "while others responded not" so the correct way of conducting the test is by replacing did with the verb or by putting it next to did ?

Hello again, UNSTOPPABLE12. Of the two choices you listed, unless you are speaking or writing in a stylistic manner for some purpose (perhaps imitating Yoda-speak), there would be no context in which you would use the latter construct. If you work around did in choice (B), you get the following:

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

You cannot eliminate did and retain the negation of the sentence within the while construct, unless you changed the sentence a bit: while others showed no such increase (or something similar). Otherwise, you could replace did in the following manner:

... with some showing increased flexibility, with others not [showing increased flexibility].

English is atypical among world languages in its adoption of a separate verb, to do, to negate an original action. It does not really make sense to do so, but that is what history has passed down to us.

Hi,

Abhi077

I am completely lost with Ellipsis. I made notes on the question by saying :
.... , while others did not (" show increased flexibility - show verb not available in the previous part, hence wrong).

Now my question is: I tried extending this idea to a question from Veritas :
" https://gmatclub.com/forum/the-plateau-in-global-warming-that-took-place-in-the-1950-s-and-60-s-i-216116.html"

The question goes: pollution from dirty factories may have played a role, just as natural variability did in ocean circulation.

I eliminated this choice saying - natural Variability did (play - required but not available in the previous half of sentence.) .
Pl enlighten me what am I missing when reading the ellipsis. Thank you

Ellipses can be tough and confusing to tackle if you lack conceptual understanding of it I suggest you go through these articles https://e-gmat.com/blogs/ellipses-in-co ... ing-verbs/

GMAT has evolved way past hard and fast rules, what may apply to one particular question might not apply to another. each question is different with respect to its structure and meaning. I hope these articles help

“with other nations … holding” —- this structure is common in colloquial speech, but the GMAT doesn’t like this at all: “with” + [noun] + [participle]. The prepositions “with” is designed to hold a noun, maybe even a modified noun, but not an entire action. This choice is incorrect.

Got this from Magoosh's blog on Absolute phrases. Considering this, shouldn't E be incorrect as well ?
D should be the right answer in my opinion. Can anybody explain this ?

No, that proposed rule is not a thing. Here's an official example where the construction they're decrying is used correctly: https://gmatclub.com/forum/starfish-wit ... l#p1084777

As for D, it definitely won't fly. After "while," we need an action. We can't just say "while others not." Although "while" certainly does not always refer to two actual simultaneous actions--sometimes it just shows contrasting ideas--it is still used grammatically as if the two things described are both events.

(B) fails the ellipsis test, where as (D) looks like the most suitable?

E might be the best of 5, but that isn't the best way to put it either.

E) Even within the same study, people responded quite differently to acupuncture with some showing increased flexibility and others not.

Using 'and' looks like a problem to me, especially with a comma after study.

Hi there, just to confirm my understanding on the usage of 'while' as a parallel marker.

please see the sentence below:

1) The opinions of politicians who are mostly guided by the vote bank while preparing their propaganda are no more relevant in this matter than those of the citizens who form most of that vote bank


a. Here 'while' is a conjunction joining two modifiers- a RPC and an ing verbal. Are these two parallel. It might be an exception. Just thinking if we also have an OG question on similar lines?

Hi,

When I open up ''show spoiler'' it gives me explanation on choice D.

saying that ''while'' usage is incorrect and a complete clause should have been there.

can't we say that option d] function as an absolute phrase and 'while' is just a preposition. Do we really need to look for a rule that 'while' begins a clause??
