Answer:
Federation system of government did the Constitution create in the United States
Step-by-step explanation:
A federation is a system of government in which a group of unified states come together under the control of a federal (aka central) government. Even though there is a federal government, a federation allows for states to make decisions about issues relevant to their state only.
This is why the constitution outlines rights and responsibilities of the federal government. The rest of the rights not guaranteed to the federal government are then reserved to the states.
