What is the appositive phrase in the sentence: Problem number 19, the final question, was difficult."?

1 Answer

The final question

Explanation:

An "appositive" word or phrase renames the word next to it.

In the sentence in question, we first read about "Problem number 19". This is the first reference we have to a question on a test.

The appositive is what comes next and renames it - "the final question".
