Final answer:
Hazor had a lower city with commoners, serfs, and slaves and an upper city that served as a ceremonial center for the ruling elite.
Step-by-step explanation:
The excavations reveal that Hazor had a lower city consisting of commoners, serfs, and slaves, as well as an upper city or citadel that was walled off from the rest of the settlement.
This upper city served as a monumental ceremonial center for ritual activities and the residence of the ruling elite, similar to the palaces and temples in Egypt and Mesopotamia.
