Which of the following originated in MesoAmerica?

Cacao cultivation originated in MesoAmerica, which is an important cultural and geographic area that includes parts of modern-day Mexico and Central America. The civilization there, especially the Olmecs, Mayans, and Aztecs, cultivated cacao trees and valued the cacao beans not only as a food source but also as currency and in ceremonial rituals. This highlights the significance of cacao in their economy and social practices.

In contrast, the other options, such as the wheel, printing press, and gunpowder, developed in different parts of the world. The wheel was primarily used in ancient Mesopotamia, the printing press is attributed to Johannes Gutenberg in Europe, and gunpowder was invented in China. This context helps clarify why cacao cultivation is the only correct answer here, connecting it directly to the region of MesoAmerica and its rich historical significance.
