What do readers have to look at closely to direct a theme??

To identify the theme of a story, you have to read through the story and understand the basics of the characterization, plot and other literary elements that are included in the story. Get to know the main subjects of the story. Make sure not to confuse the subject of the story with its theme

Explanation:

the purpose of the heading in the passage is to identify who is telling the story.

this excerpt is part of the book sugar changed the world (2010) written by marc aronson and marina budhos. as the book has been written by two people, the heading "marc" indicates that this specific excerpt is being narrated by aronson. in the fragment, marc describes his grandfather's story after hearing it from his cousin. however, there are other excerpts where budhos is the one that tells the story of her family.

aronson and budhos, who are husband and wife in real life, decided to write sugar changed the world when they found out how sugar, which had an important role in slavery and economy, changed their ancestors' lives.
