Question

1. one characteristic that the maya, inca, and aztec all shared was that they...

• practiced a theocratic form of government

• developed terrace farms for agriculture

• used the cacao bean as a form of currency

• were settled in present day mexico

Explanation:

To solve this, we analyze each option:

• The Aztec, Inca, and Maya did not all practice a theocratic form of government (Aztec had elements, but not all three uniformly).
• Terrace farming was mainly an Inca innovation, not shared by all three.
• All three civilizations (Aztec, Inca, Maya) used the cacao bean (for Aztec/Maya) or similar forms of commodity money, and the Inca had their own systems but the cacao - related or similar valuable goods as a medium of exchange was a shared economic practice in terms of using a specific good as currency.
• The Maya were in present - day Mexico, Guatemala etc., Inca in South America, Aztec in present - day Mexico, so they were not all settled in present - day Mexico.

So the correct option is the one about using the cacao bean as a form of currency.

Answer:

used the cacao bean as a form of currency
