Though slaves were treated brutally from the moment of capture, Europeans in the Old World and New managed to justify the enslaving of African people--to themselves, at least. What was one of
their main justifications for continuing the practice?
A. The plantation owners needed slaves to meet Europe's demand for sugar, rice, tobacco, and cotton.
B. The people who were against slavery didn't understand what African slaves were like.
C. The Portuguese were not going to stop buying slaves, so they might as well buy them.
D. The West Africans who made money from the sale of fellow Africans insisted the trade continue.
