baski6 · Answer

they usage is wrong in a,b,d.

Narrowed down to C and E.

C uses ascends properly. So C is my answer.

paddyboy · Answer

E it is.

Narrowing down b/w C and E, would select E coz of -
||ism -> "internal pressure of the human body and that of the ocean"
usage -> "it is essential that a diver ...  ascend  slowly...."

mukeshnathani · Answer

For the above reasons I agree that E is the best option.But I beleive that the "ascend" should be "ascends" in option E.Option C does use "ascends" but then "difference ..between" is more appropriate.Hence I beleive that option E is the best and "ascend" should be "ascends".Please correct me if I'm wrong.

ugo_castelo · Answer

E

"It is essential " requires the subjcuntive mode so "ascend"

the same for other words such as :

arrange, desire, demand, directive, pleadd, recommend, request, etc

I was trapped by "c" though at first sight

trivikram · Answer

It is not the body pressure and ocean pressure that ascends sloyly

It is the diver so....ascends is correct IMO

I will pick C

laxieqv · Answer

no, buddy, this one is subjunctive mood

According to the golden Manhattan SC book which we know is the best of the kind: you should use subjunctive mood for verbs following words and phrases such as "advice, advisable, ask, arrange,....essential, fitting, imperative, important, insist, necessary,etc....." So the verb following these indicators must be in bare-infinitive form.

SimaQ · Answer

The OA is E....

faifai0714 · Answer

Shouldn't the sentence be "...it is essential that a diver returning to the surface  be ascending  slowly or he..."

It is also a continuous subjunctive form as explained here:
 https://www.englishpage.com/minitutorials/subjunctive.html 

it should follow the word "be" after "ascend"

trivikram · Answer

shoot

you are right......

GMATT73 · Answer

Talk about pinpointing the rule! Good work Laxie.

anandsebastin · Answer

After narrowing it down to C or E, I choose  E  because "differences between" is more appropriate thatn "differences in" when comparing two things.
