The correct answer is this: SHARECROPPERS HAD TO BUY EVERYTHING FROM THE LANDOWNERS WHO CHARGED VERY HIGH PRICES.
Share cropping is a type of farming in which landowners rent their lands out to tenants in return for the share of crops grown on their lands. This is done on a yearly basis. The sharecroppers got their lands, seeds, homesteads, etc from the landowners and this made them to become more indebted to the landowners on a yearly basis, hence the circle of poverty.
