Question

select the correct pronoun to complete the sentence.
the morgans are wonderful neighbors; it was ____ who brought us this tin of cookies.
they them

Explanation:

In the sentence, we need a subject pronoun for the relative clause "who brought us this tin of cookies". "They" is a subject pronoun (used for the subject of a clause), while "them" is an object pronoun (used for the object of a verb or preposition). Here, the pronoun is the subject of the clause introduced by "who", so "they" is correct.

Answer:

they
