between A and C I will go for A because in C one's - his. (There is no antecedent for his)
What is the OA

CarlosMoraM · Answer

I go with A

C is wrong because of "allowing him" and D is wrong because of the idiom "ability to". Among the other options, I think that because is better than because of in this sentence

Shobhit7 · Answer

'Ability to' is the correct Idiom: C and D are wrong

'Because of Improving' is idiomatically incorrect: B and E are wrong.

Ans A

I remember i did some SC OG question, which had split between especially and specially. I think option with "especially" was correct in that SC problem. Can anyone tell me what is the difference between especially and specially.

LoneSurvivor · Answer

Can someone please explain the different usage of "Especially" and "Specially"

Maxximus · Answer

"Especially" is generally the preferred adverb; you will probably never see "specially" winning over "especially".

"Special" is the preferred adjective.

In other words,
"special" is preferred for the "adjective" usage and "especially" is preferred (over especially) for the "adverb" usage.

However, GMAT will not test you on only this rule; there would be other, meaty concepts involved, as is the case with this question.

Here is the video explanation for this problem-

My doubt is about non-underlined portion -- , and improve....why not improves..??

it improves...,and improve???

minalgambhir · Answer

ANSWER CHOICE ANALYSIS -

A) CORRECT
B) 'because of' is used to give the effect - the criticality of cognitive abilities does not cause improvement in brain's ability
C) If 'one' is used in the sentence, 'him' can't be used
D) 'especially' and 'specially' mean the same - so no error, 'in adapting' - wrong
E) Same as B

It is because, "improve" & "learn" are not standalone verbs. They are showing the intent "to+verb", which again is a part of the result, of a previous action.

IanStewart · Answer

The above is the "OA", and it's not in English (it needs to say " the  brain", and the last comma needs to be deleted, among other issues). There is not a good answer among the choices.
