Final answer:
In 'The Grapes of Wrath', mice and animals move into the abandoned houses of tenant farmers. The displacement of humans and subsequent occupation by animals reflect the agricultural and economic hardships of the era.
Step-by-step explanation:
Regarding the question from the novel "The Grapes of Wrath", specifically in chapter 11, the correct answer to who moves into the tenant farmers' houses would be A. Mice and animals. Within the context of the Dust Bowl and the Great Depression detailed in John Steinbeck's novel, the tenant farmers are displaced due to economic hardship and environmental disaster, and as a result, these abandoned homes become shelters for various creatures.
Throughout the narrative, Steinbeck illustrates the challenges faced by farmers who, burdened by debt and poverty, were often forced to give up their land. As banks and larger economic forces moves to foreclose and seize properties, these homes are left empty and are soon occupied by mice and other animals. This exemplifies the cycle of displacement and the broader struggles of American agrarian communities of the era. Sharecropping became a common solution for those who lost their land, a situation in which farmers would work on land owned by someone else and pay rent with a portion of their crop yield.
