Why did plantation owners begin to import African slaves to work their farms?

They believed Africans would be more loyal to them because they were from another continent.
They could get more slaves from Africa for less money than they were currently paying.
They feared attacks from Native American slaves who were skilled warriors.
They realized that people from Africa were more resistant to disease than Europeans were.

Respuesta :

They realized that people from Africa were more resistant to disease than Europeans were.

The correct answer is "They realized that people from Africa were more resistant to disease than Eureopeans were."

Africans had much greater resistance to both Old World diseases and tropical diseases, which means they were better suited to survive in warmer climates than both European colonists and Native Americans.
