Hello. You have not shown the excerpts to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
To answer this question, it is necessary that you first read all excerpts and identify what the main subject they are addressing. This subject is the main theme of the excerpt and it is on this theme that the story will stabilize. In addition, the events covered in the story should have the theme as a base, so you will be able to explain them, showing how they address the theme of the story. For example, if a story is about social inequality, the events showed people experiencing financial difficulties, suffering social problems, suffering situations of intolerance and injustice, among others.
