Why did some paleolithic people in east africa migrate to other areas between 100,000 and 75,000 years ago?

a. rival groups drove them out
b. farmland became increasingly scarce.
c. the climate became very unstable.

the answer is c sharecroppers were trapped in a cycle of poverty and debt.

explanation:

one of the major disadvantages of sharecropping system is that the sharecroppers or the planters are stucked in an unhealthy cycle of debts. this happens because planters will be allowed to loan merchandise from the land-owner and will soon be paid by the farmer in his share in the farm come harvest time. hope this !
