Answer:
commerce, housing, public baths
Explanation:
Commerce
The city served as a central point for commerce. Farmers could bring their produce into the city to trade for other goods or coins. In the forum there was generally a table where standard weights and measures could be verified. This kept people from being cheated when doing business.
Housing
There were two main types of housing in the cities. The poor and middle class people lived in large apartment buildings called insula. The majority of the people lived in insulate. The wealthy lived in private homes. You can go here to read more about Roman homes.
Entertainment
Larger Roman cities all had some public buildings for entertainment. These included an outdoor amphitheater (for events like gladiator fights), a circus (used for chariot races), a theater, and public baths.
Public Baths
Keeping clean was important to Romans living in the city. Any large Roman city had public baths where people would go to bathe. Bathing was a popular pastime for the Romans. They would hang out with their friends and even hold business meetings at the bathhouses.
