Which group would have been most likely to answer an ad for a fruit-picking job in california?
bankers on the great plains
farmers in the dust bowl
fruit growers in california
writers such as john steinbeck

B. Farmers in the dust bowl.

A great deal of people moved from territories affected by the Dust Bowl to California. Additionally, bankers, fruit growers, and writers would've had no real reason to answer such an ad because they all already had successful jobs. Farmers would've been looking for opportunities to do something they were familiar with and escape the Dust Bowl.
