Slaves were imported into the united states beginning a. with the need for consistent agricultural labor b. with a circular trade surrounding the atlantic c. when europe demanded more goods from the americas d. with economic systems requiring free labor for success

The correct answer is D. with economic systems requiring free labor for success

An early economic argument was that slavery was needed in America because there was enough workforce to work in agriculture. But in fact, slavery permitted people to own larger farms, with larger profits in farming. Many people shifted their business into agriculture at the expense of industry because of slave work.
