The most accurate response regarding the impact of the Columbian Exchange on the Old World is:
The population of Europe grew and Indigenous Americans moved from the New World to the Old World.
This reflects the introduction of new crops such as potatoes, tomatoes, and maize from the New World, which contributed to population growth and improved nutrition in Europe. The other options either misrepresent historical facts or contain inaccuracies regarding the effects of the Columbian Exchange. For instance, while diseases did have a significant impact on populations, it primarily affected Indigenous peoples in the Americas, rather than decimating European populations. The statement about African people being forced from the Old World is misleading because it focuses on the slave trade's direction rather than the direct impacts of the Columbian Exchange. Lastly, the claim that the Old World did not receive any new crops is factually incorrect, as the Columbian Exchange involved the transfer of several important food crops to Europe.
