The supremacy clause form the root of what aspect of the country’s government system

The Supremacy Clause forms the root of the aspect of "federalism" within the country's government system, since it means that although power is shared between the federal government and the states, the federal government reigns supreme

i don't get what you mean

explanation:

i confess that there are several parts of this constitution which i do not at present approve, but i am not sure i shall never approve them: for having lived long, i have experienced many instances of being obliged by better information or fuller consideration, to change opinions even on important subjects, which i once thought right, but found to be otherwise. it is therefore that the older i grow, the more apt i am to doubt my own judgment, and to pay more respect to the judgment of others.
