Answer:
You have not provided the text to which your question refers but anyway I will give you an explanation so that you can answer it yourself.
Explanation:
The theme of a text is a phrase that synthesizes or encompasses the entire text, a very brief exposition of the central idea of the writing around which the meaning of the text is organized and that gives meaning -universal- to the data or specific events to present the text
The theme of a text is not the summary of the text. We call summary the expository text capable of reporting the main idea and secondary ideas of a given text, linked by discourse connectors.
Therefore, you must identify a phrase capable of expressing the full meaning of a story, that is, a very brief exposition of its main idea, around which the rest of the secondary ideas are distributed.
