This question is incomplete since you have not provided a specific text, but anyway I will give you an answer that will be useful.
Explanation:
The motivation of a character is one of the fundamental elements when writing a story. Motivation is always relevant, but especially when it comes to the protagonist.
Motivation is what is behind every action that your protagonist undertakes. And its importance lies in the fact that it helps the reader understand why the character does what he does.
Without motivation, any narrative, be it a novel or a story, would be no more than the more or less attractive description of some facts.
