Which agency is responsible for planning, designing, constructing, operating and maintaining the nation's water resource activities and for the design and construction for Army, Air Force, and other Defense agencies?

• A. Environmental Protection Agency
• B. United States Army Corps of Engineers (USACE)
• C. National Oceanic and Atmospheric Administration
• D. Department of Transportation

Answer: (B)

The main idea here is that the United States Army Corps of Engineers is the federal agency charged with planning, designing, constructing, operating, and maintaining the nation’s water resource activities, and also with design and construction for Army, Air Force, and other Defense agencies. USACE leads many civil works projects—flood risk management, navigation channels and locks, hydropower, water supply, and ecosystem restoration—while providing engineering support for military facilities and infrastructure. This combination explains why it’s the best fit: it covers nationwide water resource planning and construction, plus military construction support for Defense departments. The Environmental Protection Agency focuses on environmental protection and regulations rather than broad water resource project development; the National Oceanic and Atmospheric Administration handles weather, climate, and oceanic science; and the Department of Transportation oversees transportation infrastructure rather than nationwide water resource programs or Defense-magency construction.
