7. where did slaves have harder lives?

Southern states

This is because there are more farms and plantations in the south based on the landscape there so more slavs were required to work harder. Unlike the north where there were no slaves.

You don't have answer choices, but a smart answer would be large plantations. This is because they spent most of their time on large plantations working. Although they worked in the southern states, specifically they were on large plantations.
