Question

select the appositive or appositive phrase.
prevailing over another publisher by just twenty minutes, william byers published denver’s first newspaper, the rocky mountain news.

Explanation:

To identify the appositive or appositive phrase, we recall that an appositive is a noun or noun phrase that renames another noun right beside it.

In the sentence "Prevailing over another publisher by just twenty minutes, William Byers published Denver’s first newspaper, The Rocky Mountain News," the phrase "The Rocky Mountain News" renames the noun "newspaper" (specifically "Denver’s first newspaper").

An appositive renames a nearby noun. Here, "The Rocky Mountain News" renames "Denver’s first newspaper".

Answer:

The Rocky Mountain News
