The Central Valley Project’s water is primarily used for:

• A. Industrial use
• B. Agriculture
• C. Domestic use
• D. Recreation

Answer: (B)

The main idea is that this water project is designed to support farming. The Central Valley Project was built to store and convey water so farmers in California’s Central Valley can irrigate their crops, turning a dry region into a productive farmland area. Because growing crops requires steady irrigation, the largest share of the project’s water is allocated for agricultural use. Other uses—such as municipal/domestic supply, industrial use, or recreation—exist, but they come after and rely on the water allocated for farming. That’s why the best answer is agriculture.
