what does the supremacy clause do?\nit establishes a way to change the constitution.\nit establishes rights…

Brief Explanations:

The Supremacy Clause in the U.S. Constitution makes federal law and the Constitution the supreme law of the land, which relates to the relationships between states and the federal - government. It doesn't establish a way to change the Constitution (that's the amendment process), doesn't directly establish rights for citizens in different states (though it can impact them), and doesn't solely establish a foundation for government.

Answer:

It establishes relationships between states.
