Question

The authority of the U.S. national government is based in Constitutional language. Which of these constitutional clauses does NOT support the authority of the national government? (Points : 1) Interstate Commerce Clause Property Clause Supremacy Clause Treaty Clause

Answer 1

It would be the "Interstate Clause" that does not support the authority of
the national government, since this is simply the "Commerce Clause". The interstate aspect did not occur until later.
