Answer:
The correct answer is B: They left their land and migrated to California.
Step-by-step explanation:
Life on the Great Plains was difficult because farmers had to face different challenges every day, as the land was very dry and flat. The biggest obstacle for the farmers was the fact that Great Plains suffered from a drought, a period without rainfall.
The lack of rainfall caused wheat fields to turn into a Dust Bowl. The high winds picked up the topsoil and created enormous dust storms, while the persistent drought caused crops to fail, leaving the land exposed to wind erosion. Therefore, the lack of rainfall and the Dust Bowl forced many of Great Plains farmers to head west to California in search of better living conditions.
