What is the effect of the chapters which come between the narrative about the Joads? how would the elimination of those chapters affect the meaning and impact of the novel?

The narrative shifts dramatically between different points of view. In some chapters, the narrator describes events broadly, summarizing the experiences of a large number of people and providing historical analysis. Frequently, in the same chapters, the narrator assumes the voice of a typical individual, such as a displaced farmer or a crooked used-car salesman, expressing that person’s individual concerns. When the narrator assumes the voice of an anonymous individual, the words sometimes sound like what an actual person might say, but sometimes they form a highly poetic representation of the anonymous indiv-idual’s thoughts and soul. The chapters focusing on the Joad family are narrated primarily from an objective point of view, representing conversations and interactions without focusing on any particular character. Here, the characters’ actions are presented as an observer might witness them, without directly representing the characters’ thoughts and motivations. At certain points, however, the narrator shifts and presents the Joads from an omniscient point of view, explaining their psychologies, characters, and motivations in intimate detail.
