In the federal system of government in the United States, the powers kept by the states are known as reserved powers. These are powers that are not specifically granted to the federal government by the Constitution and are not prohibited to the states, allowing state governments to exercise authority in areas that are not explicitly outlined in federal law.
To clarify the terms:
- Implied powers: These are powers not explicitly stated in the Constitution but are inferred from the enumerated powers.
- Enumerated powers: These are the powers specifically listed in the Constitution that belong to the federal government.
- Concurrent powers: These are powers that are shared by both the federal and state governments.
So the correct answer is reserved powers.
