Final answer:
The abundant water supply facilitated by aqueducts allowed for cleanliness and public health amenities in Roman cities.
Step-by-step explanation:
The abundant water supply facilitated by aqueducts allowed for cleanliness and public health amenities in Roman cities. The Romans built aqueducts to bring clean water from sources far from the city, supplying Rome and other cities with a reliable drinking water supply. This improved sanitation and cleanliness by allowing water for bathing, the construction of bath houses, and the development of a sewer system to flush waste out of the city.
