In the following four assessment items, choose the sentence in which the appositive or appositive phrase is essential to the sentence and punctuated correctly.

A)This trip, the result of an election bet, took ten days.
B)This trip the result, of an election bet, took ten days.

The sentence in which the appositive or appositive phrase is essential to the sentence and punctuated correctly is:

A)This trip, the result of an election bet, took ten days.

The correct sentence is A) "This trip, the result of an election bet, took ten days."

To determine which sentence has the appositive or appositive phrase punctuated correctly and is essential to the sentence, we need to understand what an appositive is and how it should be punctuated.

An appositive is a noun or noun phrase that renames or identifies another noun right beside it. It provides additional information about the noun it is modifying. Appositives are often set off by commas, but there are certain cases where they are essential to the sentence and no commas are used.

Let's analyze the two sentences:

A) This trip, the result of an election bet, took ten days.
B) This trip the result, of an election bet, took ten days.

In sentence A, the appositive phrase "the result of an election bet" provides additional information about the trip. The commas around the appositive phrase indicate that it is not essential to the sentence. The sentence could still be understood and convey the same meaning without the appositive phrase.

In sentence B, the appositive phrase "the result" is not enclosed by commas. This implies that it is essential to the sentence and cannot be removed without changing the meaning or clarity of the sentence.

Therefore, sentence B is the correct answer because it has the appositive phrase "the result" punctuated correctly and is essential to the sentence.
