The correct responses regarding why there were fewer slaves in the backcountry of the Southern colonies than those areas closer to the coast are:
- Colonists in the backcountry were primarily self-sufficient.
- Colonists in the backcountry were poor and couldn’t afford slaves.
While some backcountry settlers may have had opposing views on slavery, the prevalence of poverty and self-sufficiency were the primary reasons for the fewer numbers of enslaved individuals in those areas. The statement about slaves not being able to travel to the backcountry is not a significant factor in this context.
