This question is flawed 'Forcing children who show a preference for their left hand to use their right hand' is third person singular
so it should be 'results' not result.

Hello parijit, how are you?

Yes you are right, our subject is "forcing children" - v-ing as noun, hence SINGULAR.
But did you noticed modal verb "may" befor main verb?
This is the main trick, we use origical verb form without "to" after the modal verbs, thus everything is okay with our subject-verb agreement.

Questions are welcome, hope it will be helpful ;)

Forcing children who show a preference for their left hand to use their right hand may not only result in speech difficulties, creating behavioral problems.

Meaning analysis: If we force children who use their left hand to use their right hand this can lead to 2 things:
1. may result in speech difficulties 2. may create behavioral problems

Error analysis: let's see the sentence structure -->

From the meaning analysis we know that forcing children is not good and it leads to 2 things, but this 2 parts are not connected properly. Idom "not only" is missing its pair "but also". Moreover ",+v-ing" is not good way to present it. If there was no "not only", then "creating" will be okey suggesting "how" aspect of "may result in speech dificultires". But now we require "but also" becouse "not only" is in non-underlined part of the orginal sentence.

In reality "not only X ... but also Y" is one of the most favourite idioms that GMAT tests us.
And we are going to be really lucky if we see this idiom in real GMAT in D day.

There is a lot of variations of this idiom (thank you @daagh)
Whenever you spot this idiom, just keep in mind that X // Y.

A. difficulties, creating behavioral problems
(wrong as explained in error analysis)

B. difficulties but also creating behavioral problems
(we've back our missing "but also", but "creating" is not // to result)

D. difficulties; it also creates behavioral problems
(we don't need here any IC, our "not only" is in non-underlined part, "but also" is required here)

E. difficulties; behavioral problems themselves are also created by it
(same as (D), too wordy construction, "themselves"-?? "it"-refers to what???)



C. difficulties but may also create behavioral problems

C is the answer

"Not only" must be followed by "but also", eliminating A,D and E.
Option B: "result in" is not parallel with "creating".
C is the right answer.

The best/excellent answers get kudos, which will be awarded after the answer is revealed.
There may be no best/excellent answers, or a there may be a few excellent answers!

Official Explanation:


The underlined portion of the sentence contains the verb creating and the non-underlined portion of the sentence contains the verb result, so check for parallel construction errors. The non-underlined portion of the sentence also contains the beginning of the idiomatic construction not only…but also, so check for idiom errors. The verb creating is not parallel to the verb result, so there is a parallel construction error. Because the correct idiomatic structure is not only…but also and the underlined portion of the sentence does not complete the idiom with but also, there is also an idiom error. Eliminate choice A for both the parallel construction and idiom errors and look for obvious repeaters. Choice B is an obvious repeater of the parallel construction error since it also uses the verb creating, so eliminate choice B. Now, evaluate the remaining answer choices individually, looking for reasons to eliminate each.

Choice C fixes the original parallel construction error by using the verb create which is parallel to the verb result, fixes the idiom error by using the correct construction may not only…but may also, and introduces no new errors, so keep choice C. Choice D uses the verb creates which is not parallel to the verb result and uses the unidiomatic construction may not only…it also, so eliminate choice D for both the parallel construction and idiom errors. Choice E uses the verb created which is not parallel to the verb result and uses the unidiomatic construction may not only…also, so eliminate choice E for both the parallel construction and idiom errors.

Choice A: No. The verb creating is not parallel to the verb result and the idiom not only…but also is incorrectly written as not only. Parallel construction; Idiom.

Choice B: No. The verb creating is not parallel to the verb result. Parallel construction.

Choice C: Correct.

Choice D: No. The verb creates is not parallel to the verb result and the idiom not only…but also is incorrectly written as not only...it also. Parallel construction; Idiom.

Choice E: No. The verb created is not parallel to the verb result and the idiom not only…but also is incorrectly written as not only...also. Parallel construction; Idiom.

The correct answer is choice C.

Good catch! Simple answer: it is NOT justified. There is no valid answer to this unofficial question.

'Not only' result, 'but also' create, option C makes most sense.
