Question

find the appositive. if it is nonrestrictive, set it off with commas. if it is restrictive, submit the text without making any changes.
the lyricist oscar hammerstein ii is the only person named oscar to have won an academy award.

Explanation:

The phrase "Oscar Hammerstein II" is a nonrestrictive appositive. It provides extra, non-essential information about the noun "the lyricist" (we already know we're talking about a specific lyricist, and this name adds additional context that doesn't narrow down the identity of the lyricist). Nonrestrictive appositives require commas to set them apart from the main clause.

Answer:

The lyricist, Oscar Hammerstein II, is the only person named Oscar to have won an Academy Award.
