A) NO CHANGE
(B) backgrounds-is
(C) background-are
(D) background-is



Answer :

The correct answer is:

(B) backgrounds-is

In this sentence, the subject is "American society," which is singular. Therefore, the verb should be "is" to match the singular subject. Additionally, the prepositional phrase "from vastly different backgrounds" does not affect the subject-verb agreement, so the correct form should be "backgrounds-is."
