What characterizes the society of the Incas?

The society of the Incas is characterized by a strong central government that unified the diverse groups within their empire. This centralization was crucial to the administrative efficiency and stability of the Inca civilization, which extended over a vast territory across the Andes Mountains. The Sapa Inca, or emperor, held supreme authority and was considered both a political leader and a divine figure. This central government oversaw various aspects of life, including taxation, resource distribution, infrastructure development, and military organization, which allowed for the integration of different cultures and communities under one rule.

The other choices do not accurately reflect the primary characteristics of Inca society. For instance, while the Inca Empire did encompass some coastal regions, it was primarily located in the mountainous areas of Peru and extended into parts of Ecuador, Chile, and Argentina. The Incas had a rich cultural diversity and utilized local languages, with Quechua being the most prominent; however, the notion of speaking multiple languages does not define their society as strongly as their unified governance structure. Lastly, rather than remaining isolated, the Incas engaged in trade and interaction with various neighboring groups, which contributed to their wealth and the interconnectedness of their empire.
