The four functions of government are derived from which part of the U.S. Constitution?

• A. Preamble of the U.S. Constitution
• B. Articles of Confederation
• C. Bill of Rights
• D. Ninth Amendment

Answer: (A)

The Preamble of the Constitution states the purposes of government, and those purposes give rise to the four broad functions: establishing justice, insuring domestic tranquility (keeping order), providing for the common defense, and promoting the general welfare. Because these aims are spelled out at the very start, this part is what guides what the government is responsible for doing. The rest of the Constitution sets up how those aims will be achieved—through the structure of government and its powers. The Articles of Confederation belong to a prior framework and aren’t part of the current Constitution; the Bill of Rights and the Ninth Amendment focus on protecting individual rights rather than defining government functions.
