Question

select the appositive or appositive phrase. after buying their new house, our new neighbors, the mccormicks, embarked on an ambitious renovation project, turning their garage into a photography studio.

Explanation:

An appositive phrase renames or identifies a noun. In the sentence, "the McCormicks" renames "our new neighbors", so it's the appositive phrase. The other phrases ("After buying their new house", "turning their garage into a photography studio") are not appositive (the first is adverbial, the second is participial).

Answer:

the McCormicks
