Environmentalists

Environmentalists associated with the United Nations Environment Programme predict that if the current trends associated with global warming continue, thousands of acres of pristine land is in danger to undergo potentially irrevocable changes that could alter the planet's ecosystem forever.


(A) is in danger to undergo
(B) are in danger of undergoing
(C) is in danger of undergoing
(D) are in danger to undergo
(E) are in danger for undergoing

I am confused here, what is the subject of the clause after the comma?

IMO B

IMO Subject is 'thousands of acres'
'In danger of' is correct idiom

OA is B. Vaibhav, in the clause that begins with "thousands of acres of pristine land" would it make sense if you remove the prepositional phrase "of pristine land".Manhattan SC book states that middleman "of pristine land" be removed and therefore the subject will be 'thousands of acres'

But i also read that the subject can be from prepositional phrase if you cannot remove the object of preposition from the clause, but i guess thats the case when we are dealing with a PART of numbers as in "Half of the pie IS ... and Half of the Carrots Are.."

[vaibhav.iit2002]

You are right.

'thousands of acres' is different from 'half of'.

I selected C thinking that subject is land. For e.g., if we say, thousands of litres of water is sufficient to form a well.
Will the correct sentence be
thousands of litres of water are sufficient to form a well???
