Final answer:
The invention of the Chain Pump helped farmers by aiding in irrigation and increasing agricultural productivity.
Step-by-step explanation:
The invention of the Chain Pump helped farmers by aiding in irrigation and increasing agricultural productivity. The chain pump was a device used to lift water from a lower to a higher elevation, making it easier to water crops and irrigate fields.
By using the chain pump, farmers were able to bring water to their fields more efficiently, allowing them to grow crops in arid regions or during dry seasons. This improved irrigation system resulted in increased crop yields, which provided greater supplies of food for society and reduced its cost.
Overall, the chain pump played a significant role in the agricultural revolution by helping farmers overcome the limitations of manual labor and animal power, ultimately leading to greater agricultural productivity and food security.
