Final answer:
The powers not given to the U.S. or prohibited to the states by the U.S. Constitution are specifically reserved for the states or the people.
Step-by-step explanation:
The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people. This is specified in the Tenth Amendment of the U.S. Constitution, which affirms the states' reserved powers. The Tenth Amendment states, 'The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.' This means that any powers and rights not given to the federal government or specifically prohibited to the states belong to the states or the people.
