Please answer its urgent! thanks! (40 points) Incans and Aztecs had a few characteristics in common with the Afro-Eurasia civili
alex41 [277]

Answer: D) "Since horses were not introduced to the Americas until Columbus, the Aztecs and Incas did not use horses or advanced weapons, while the Afro-Eurasians had highly developed cavalries and weaponry."

The answer is not A because Afro-Eurasia was composed of giant empires and governments, not small ones. The answer is not B because slavery was acceptable in the Incan and Aztec empires <u>as well as</u> in the Afro-Eurasia. Finally, it can't be C because in Afro-Eurasian governments, <u>only a few</u> were centered on religious beliefs, not all.
