Final answer:
Roman aqueducts provided a gravity system to deliver clean water to cities.
Step-by-step explanation:
The purpose of a Roman aqueduct was to provide a gravity system to deliver clean water to cities.
The aqueducts were engineered by the Romans to transport water from a water source, such as a spring or river, to the cities and towns, ensuring a steady supply of clean water for drinking, bathing, irrigation, and various other purposes.
An example of a Roman aqueduct is the Pont du Gard in France, which was constructed in the 1st century AD and carried water over 30 kilometers to the city of Nimes.
