Question

which statement summarizes how portuguese traders amplified the slave trade? (1 point)
portuguese traders introduced slavery to africa.
portuguese traders engaged in mass kidnapping of the locals to sell into slavery.
portuguese traders bought many enslaved people for export to europe.
portuguese traders created entrepôts from which large numbers could be shipped overseas to meet the growing demand for forced labor on colonial plantations.

Explanation:

Slavery already existed in Africa before Portuguese traders. They did not introduce it. Mass - kidnapping was not the main way they amplified the slave trade. While they bought enslaved people for export, the creation of entrepôts (trading - ports) to ship large numbers to meet the demand of colonial plantations was a major factor in amplifying the slave trade.

Answer:

Portuguese traders created entrepôts from which large numbers could be shipped overseas to meet the growing demand for forced labor on colonial plantations.
