Question

Which words in the sentence make up the appositive phrase?
Which word does it rename?
The reference book, the one about Earth and its rocks, is missing from the shelf.
a. from the shelf; renames missing
b. and its rocks; renames Earth
c. the one about Earth and its rocks; renames book
d. reference book; renames one

Answer 1

The correct answer here is C. The appositive phrase is a set of words, usually separated by commas, that define the noun, or the subject in more detail. Here, the book is more thoroughly described through the use of the appositive phrase, "the one about Earth and its rocks".
