Name one thing the U.S. Constitution does.

Why this is the answer

The Constitution does three jobs at once. It creates the government: its first three articles set up Congress, the presidency and the courts, the three parts of the federal government. It defines what each part may do and where its power stops, so it both grants power and limits it. And, through its amendments, it protects the rights of the people, starting with the Bill of Rights. Any one of the four official answers is enough at the interview. Memory hook: build, limit, protect. The Constitution builds the government, limits its powers and protects your rights.
