During the sixteenth and seventeenth centuries, Africa played a significant role in the global economy primarily through the exploitation of its resources and participation in the transatlantic slave trade. One of the key contributions of Africa during this period was its export of gold, ivory, and enslaved people while under the control of Portugal. This involvement not only supplied European powers with valuable commodities but also integrated African economies into global trade networks, particularly the emerging Atlantic economy. Thus, the most accurate response would be:
Africa sold gold, ivory, and enslaved people while under the control of Portugal.
