Which of the following were effects of the slave trade?

A. Changed the makeup of the population of Africa and America

B. Lowered the population of Africa significantly.

C. Caused cultural changes in the Americas.

Explanation:

Even before, slave trades, were already common in Africa. However, a drastic changed occurred with the "Atlantic Slave Trade." This lowered the population of Africa (mainly, Central and West areas) significantly because many of the slaves were transported to America.

The African Kings also took part in the trading. They traded the Africans for different goods, such as guns and ammunition. So, this significantly changed the makeup of the population of Africa and America.

America became the home of many Africans who were enslaved and transported into the country. This then caused a cultural change in America. Many of the enslaved Africans were used by the Americans as helpers in their businesses. They assisted in the sugar and cotton plantations, mining, harvesting in the rice fields and also provided domestic service. Many of the European settlers became immediate landowners, thus they were searching for more workers in their lands.

i would say your answer would be the second option.

hope this !
