Final answer:
Slavery in the North in the eighteenth century was limited and uncommon, with slaves often working in skilled trades or as domestic servants, and not being as central to the economy as in the South.
Step-by-step explanation:
The statement that accurately describes slavery in the North in the eighteenth century is that it was limited and uncommon. While slavery existed in the North, it was not as economically integral as in the South. Most northern slaves lived in or near coastal urban regions and were employed in a variety of jobs including domestic servants, laundresses, dock workers, and skilled labor such as shipbuilding and crafts. In the North, it was common for slaves to work alongside their masters rather than on large agricultural operations. Though slavery was more widespread in southern colonies, it was nonetheless an important part of the economy in the Northern middle colonies as well.
