Step-by-step explanation:
John Steinbeck included intercalary chapters in The Grapes of Wrath to tell a bigger story about the Dust Bowl. These intercalary chapters serve as a narrative device that provides a broader context for the events experienced by the main characters, the Joad family. They depict the experiences of different characters and groups affected by the Dust Bowl, such as the migrants, the farmers, and the big companies. By doing so, Steinbeck emphasizes the social and economic impact of the Dust Bowl on a larger scale, beyond the Joad family's personal story.
