What was one major function of aqueducts in ancient Rome?

• A. To transport troops
• B. To supply water to cities
• C. To drain swamps
• D. To transport goods by road

Answer: (B)

Aqueducts were built to deliver fresh water to cities. They used gravity to move water from distant springs into urban centers, feeding drinking supplies, public baths, fountains, and sanitation systems. The arches and channels were engineered to maintain a gentle slope over long distances, allowing a steady flow without pumps. This is why the major function is supplying water to cities. Other tasks like moving troops, draining swamps, or transporting goods by road were handled by other infrastructure (military roads, drainage systems, and road networks), not by aqueducts.
