1. What is said by Mrs. Shaw Graves (Aunt Sally) that shows how slaves were dealt with like property?

What she says about slaves being a property is:

“You see there was slave traders in those days, jes’ like you got horse and mule an’ auto traders now. They bought and sold slaves and hired ‘em out. Yes’m, rented ‘em out. Allotted means somethin’ like hired out. But the slave never got no wages. That all went to the master. The man they was allotted to paid the master.”

Explanation:

As can be seen in the paragraph above, Aunt Sally states that slaves are treated as property, because, like objects, they are sold, bought, lent and rented. They work and receive no wages at all, they have no right to anything, nor the very life that belongs to their "master" as everything related to slavery.

interdependence is when all participating groups and individuals depend on each other. if you depend on one anothers goods, you end up trading in order to get the items you're looking for. (for ex: if i have food and you have water, we trade in order to depend on each other to live)
