Each of the pieces of art in the living room _____ from a different part of the world.

a) is
b) isn't
c) are
d) aren't

I think it is C...?

Nope.

Subjects are not in prepositional phrases.

If you put parentheses around the prepositional phrases, you'll easily see the subject.

Each (of the pieces) (of art) (in the living room) _____ (from a different part) (of the world).

So I would say it is A then?

Yes.

Okay thank you.

You're welcome.

To determine the correct answer, we need to identify the subject of the sentence. In this case, the subject is "Each of the pieces of art." Since "each" refers to individual items separately, it takes a singular verb.

Option a) "is" is the correct answer because it agrees with the singular subject "Each of the pieces of art." Therefore, the correct choice is not C, but A.
