Answer:
1. crop-lien 2. sharecropper 3. landowner 4. merchant
Explanation:
The crop-lien system often locked poor farmers into a cycle of debt. Under the system, a sharecropper would farm a rented section of land and pay the landowner after the harvest. Poor farmers often purchased tools and supplies on credit as well, further extending their debt to a merchant .
The crop-lien system allowed for landowners to rent farmland to poor farmers who would later pay the landowner, however since the farmer needed tools they would ask a merchant for tools which would they have to pay and thus being even deeper into debt. It's like if you were to open a restaurant but needed to rent the place and rent the kitchen utensils and took out a loan to buy the supplies as well. In the end, you would have almost no profits and may not have enough to pay everyone you owe and your staff.
