What is the purpose of the Preamble to the Constitution?

• A. To list the exact powers of Congress.
• B. To state the goals and purposes of the U.S. government, such as forming a more perfect union, establishing justice, ensuring domestic tranquility, providing for the common defense, promoting the general welfare, and securing the blessings of liberty.
• C. To describe the Bill of Rights.
• D. To specify the number of Supreme Court justices.

Answer: (B)

The main idea the Preamble communicates is the goals and purposes behind the Constitution’s framework. It explains why the document exists: to form a more perfect union, establish justice, ensure domestic tranquility, provide for the common defense, promote the general welfare, and secure the blessings of liberty. These are the broad aims that guide how the government is created and how its powers should be used.

The Preamble isn’t a list of powers or a rights document. The powers of Congress and the government are laid out in the main body of the Constitution, especially in the articles that assign and describe those powers. It also isn’t a description of the Bill of Rights, which are specific protections for individual rights added later as amendments. Nor does it set the number of Supreme Court justices; that detail is determined by Congress through law.

So the Preamble serves as a statement of purpose and direction: it tells us the objectives the constitutional system is designed to achieve and signals that the government’s authority comes from the people.
