Aztecs, Incas, and Mayans are primarily associated with which region?

The Aztecs, Incas, and Mayans are primarily associated with Native South America and Mesoamerica. This region includes parts of modern-day Mexico, Central America, and the Andean areas of South America. The Aztecs were located mainly in what is now Mexico, the Maya civilization spanned parts of Mexico, Guatemala, Belize, and Honduras, while the Incas were predominantly in the Andean region of South America, particularly in modern Peru and extending into Ecuador and Chile.

This answer is correct as it encompasses the diverse cultures and remarkable civilizations that thrived in these regions, renowned for their contributions to agriculture, architecture, mathematics, and astronomy. The civilizations had intricate societal structures, advanced engineering feats such as the Inca road system, and significant achievements in art and writing among the Maya. Together, these cultures significantly shaped the historical landscape of Native South America. Other regions listed, such as North America and Europe, do not encompass the heartlands where these three civilizations developed. Australia, being geographically separate and culturally distinct, is also not associated with these ancient civilizations.
