What is one power that is reserved for the states?

The power that is reserved for the states is the ability to conduct education. This authority stems from the Tenth Amendment of the U.S. Constitution, which states that any powers not specifically granted to the federal government are reserved for the states or the people. Education has traditionally been seen as a state responsibility, allowing each state to establish its own system of public schools, curricula, and educational standards.

In contrast, the other options pertain to powers that are either specifically granted to the federal government or shared with it. For instance, coining money is a power explicitly designated to the federal government under Article I, Section 8 of the Constitution. Declaring war also falls under federal authority, as it is a power assigned to Congress in the same section. Lastly, regulating immigration is primarily managed by the federal government, which has the authority to set policies and enforce laws regarding immigration on a national level.
