What is one power of the federal government?

The Constitution gives the FEDERAL (national) government certain ENUMERATED POWERS, including: (1) print money (only the federal government can create currency); (2) declare WAR; (3) create an ARMY and military forces; (4) make TREATIES with foreign nations; (5) regulate interstate commerce; (6) establish post offices; (7) coin and regulate money; (8) establish naturalization rules (immigration/citizenship); (9) establish federal courts. Any ONE of these is acceptable on the USCIS test. The 10th Amendment reserves all other powers to the STATES or to the people. State powers include: provide schooling and education; provide protection (police); provide safety (fire departments); give a driver's license; approve zoning and land use. Some powers are SHARED (federal and state both can do them): tax, build roads, make and enforce laws, establish courts.
