Which device uses containers on a chain loop to move water for irrigation?

• A. Water Wheel
• B. Ditch Irrigation
• C. Chain Pump
• D. Wind-Powered Pump

Answer: (C)

The idea being tested is how a pump with a chain loop and buckets lifts water for irrigation. A chain pump carries a sequence of containers attached to a loop that runs over wheels. As the wheel turns, buckets fill with water at the bottom, travel up the chain, and dump into an elevated channel or trough, delivering water to fields. This chain-of-containers mechanism is what makes it fit the description exactly. In contrast, a water wheel powers lifting by turning a wheel with buckets, but not via a linked chain of containers. Ditch irrigation involves channels and canals that transport water along the ground rather than lifting it up. A wind-powered pump uses wind to drive the pump mechanism, not a belt of buckets on a chain.
