Final answer:
Advanced cities in Sumer had a redistribution system and relied heavily on agriculture for economic production.
Step-by-step explanation:
The advanced cities in Sumer were characterized by a variety of economic activities. One prominent economic activity was the redistribution system. The city-states collected agricultural goods as taxes and stored them in palaces and temples. These stored goods were then redistributed to artisans, merchants, and officials who could not grow their own food. Another significant economic activity was agriculture. Although a majority of the population lived in cities, agriculture and animal husbandry were the main sources of economic production. The land was controlled by temples, kings, or powerful landowners and worked by semi-free peasants who were tied to the land.
