Final answer:
McElveen's descriptions of enslaved people in the domestic slave trade reveal harsh living conditions and the forced separation of families.
Step-by-step explanation:
McElveen's descriptions of enslaved people tell us about the harsh living conditions that existed in the domestic slave trade. Enslaved people were forced to endure difficult and dangerous work, with many facing physical punishment and separation from their families. The domestic slave trade involved the sale and transportation of enslaved individuals, often being taken from the Upper South to the Lower South to meet the demand for cotton and sugar economies. The closure of the Atlantic slave trade in 1808 further increased the demand for enslaved African Americans in the domestic market.
