Ancient history

What action would have been possible only after the start of columbian exchange?

The Columbian Exchange refers to the transfer of plants, animals, diseases, and technologies between the Americas, Europe, and Africa, following the voyages of Christopher Columbus in the late 15th century. This exchange had a profound impact on both the Eastern and Western Hemispheres.

One action that would have been possible only after the start of the Columbian Exchange is the cultivation of corn (maize) in Europe. Corn was native to the Americas and was introduced to Europe by Spanish explorers. Prior to the Columbian Exchange, corn was not known in Europe and could not have been cultivated there.
