Sam was more than halfway home now. go back and give them a piece of his mind? sun was almost setting. probably be better to take the shortcut. which one called him a baby? was it tucker? tomorrow's saturday. should probably go back and tell him off right now what is most likely the author's purpose for using this narrative style?

A To explore a  situation through the differing perspectives of two authors.

Explanation:

First of all, we can observe that the initial phrase is in past active objective voice and written in the "third person" point of view. Which means someone narrated the moment, someone who was not him, the tale's narrator. Second, the initial sentence is followed by an active voice phrase, but the difference between the two phrases is that the second one is in present and written in the "first-person" point of view. This means it represented the thoughts of someone, in this cases Sam's Thoughts.

Third, all the paragraph's structure is developed in this sequence: narrators sentence to contextualize, followed by Sam's (main role character) thoughts to dive deep in the moment of the event and his mind.
