Step-by-step explanation:
The Aztec Empire was not a fully sedentary society. The correct answer is B) No, semi-nomadic. While the Aztecs did establish permanent settlements, they were also known to engage in nomadic practices such as warfare and tribute collection. They would often conquer neighboring territories and impose their rule, requiring regular tribute payments. However, they did have semi-permanent agricultural villages and their capital city, Tenochtitlan, was a thriving urban center.
