Hi experts,

Can you please assist me in understanding the below question?

Because of differences in the human body's internal pressure and the ocean's, it is essential that a diver returning to the surface ascends slowly or they will suffer a painful condition known as the "bends."

a. differences in the human body's internal pressure and the ocean's, it is essential that a diver returning to the surface ascends slowly or they
b. the difference between the human body's internal pressure and the ocean's, it is essential that a diver returning to the surface ascend slowly or they
c. the difference in the human body's internal pressure and that of the ocean, it is essential that a diver returning to the surface ascends slowly or he
d. differences in the human body's internal pressure and that of the ocean, it is essential that a diver returning to the surface ascend slowly or they
e. the difference between the internal pressure of the human body and that of the ocean, it is essential that a diver returning to the surface ascend slowly or he

The OA is E. OE is - The phrase "difference between" correctly replaces "differences in." Additionally, the verb "ascend" is in the subjunctive mood. Finally, the singular pronoun "he" correctly refers to the singular "a diver."

My question is how do we see the mood of the verb -Ascend?
Also, how do we spot the subjunctive mood ?

Sentences with subjunctive mood have the following structure regardless of the subject:

that + the infinitive form of the verb without 'to'.

Subjunctive mood is used to represent somebody's recomondation, hope, desire, order etc. for someone else.

For example: I hope that he WIN the game.

In the same manner in this sentence 'essential that' should be followed by 'ascend'.

it is essential that a diver returning to the surface ascend slowly or he

Hi prachigautam, not sure if you noticed the structure a diver ascend.

With a diver (singular), you would normally expect singular verb ascends. However, the presence of ascend here is a hint of the usage of subjunctive.

Our book EducationAisle Sentence Correction Nirvana discusses Subjunctive, its application and examples in significant detail. If someone is interested, PM me your email-id; I can mail the corresponding section.
