True or False: The U.S. Constitution clearly defines rules for public health.

• A. True
• B. Not specified
• C. Both true and false
• D. False

Answer: (D)

The main idea is that the Constitution provides a framework for government powers, not a detailed, explicit set of public health rules. Public health authority mainly rests with the states through their police powers—their power to protect the health, safety, and welfare of residents. The Constitution does not spell out specific public health policies; it assigns powers and sets limits, with the Tenth Amendment reserving non‑enumerated powers to the states and the federal government acting only under its enumerated powers (such as the Commerce Clause, the Spending Power, and constitutional protections) to address nationwide concerns when appropriate. Because there isn’t a single, clearly defined set of public health rules written into the Constitution, the statement is false.
