What is one power of the states?

Under the 10th Amendment of the Constitution, powers not delegated to the federal government nor prohibited to the states are RESERVED to the states or to the people. State government powers include: PROVIDE SCHOOLING AND EDUCATION (most public schools are state and local responsibility, though there's federal involvement); PROVIDE PROTECTION (state and local police); PROVIDE SAFETY (state and local fire departments); GIVE A DRIVER'S LICENSE (each state issues its own); APPROVE ZONING AND LAND USE (local government primarily, under state authority). Any ONE of these is acceptable on the USCIS test. Federal powers (printing money, declaring war, making treaties) are NOT state powers. Some powers are shared between federal and state governments: taxation, building roads, making and enforcing laws, establishing courts. The American system of FEDERALISM divides power between the national and state governments.
