What is the primary role of the Congressional Budget Office?

• A. To provide nonpartisan budgetary and economic analysis to Congress
• B. To draft and pass budget legislation
• C. To implement federal programs
• D. To oversee federal agencies

Answer: (A)

The main idea this question tests is what the Congressional Budget Office does to support lawmakers. The CBO serves as a nonpartisan source of budgetary and economic analysis for Congress, providing objective cost estimates and projections that help members understand how proposed legislation would affect spending, revenues, and deficits. This analytic role helps lawmakers compare options and determine the budgetary impact of different policy choices.

It’s not about drafting or passing laws, which is what Congress does, nor about implementing federal programs, which is done by executive agencies. It also isn’t about overseeing agencies—that function falls to other bodies that audit or supervise agencies. The strength of the CBO lies in giving Congress clear, nonpartisan analysis to inform those decisions and budget scores.
