Question

which best describes what drew migrants to california in the 1930s?
opportunities in coal mining
family that had migrated previously
the promise of free housing
the promise of fruit - picking jobs

Explanation:

In the 1930s, the Dust Bowl displaced millions from the Great Plains. California's agricultural industry advertised abundant fruit-picking jobs, which attracted these migrants. Coal mining was not a major draw, free housing was not offered, and family ties were a secondary factor compared to job opportunities.

Answer:

the promise of fruit-picking jobs
