The answer is B: Move to California.
Explanation for each option:
A. Get a loan from the bank - This option is incorrect. In Chapter 5 of "The Grapes of Wrath," the owners do not suggest that the tenant farmers get a loan from the bank. Instead, they are more focused on the economic pressures and the need to mechanize farming, which leads to the displacement of the tenant farmers.
B. Move to California - This option is correct. In Chapter 5, the landowners and representatives of the banks suggest that the tenant farmers move to California. They imply that there are opportunities for work and a better life there, even though this advice is given more out of convenience for the landowners than out of genuine concern for the farmers' well-being.
C. Start driving tractors - This option is incorrect. While the chapter does discuss the introduction of tractors and mechanized farming, the suggestion is not for the tenant farmers to start driving tractors. Instead, the tractors are part of the reason the tenant farmers are being displaced.
D. Buy their own land - This option is incorrect. The tenant farmers are being evicted because they cannot afford to buy their own land. The economic situation and the power of the banks make it impossible for them to purchase land.
In summary, the correct answer is B: Move to California, as this is the suggestion given to the tenant farmers by the landowners in Chapter 5 of "The Grapes of Wrath."
