Which of the following best explains the major source of state government power during the period of dual federalism?

Question

A. the Supreme Court's decision in United States v. Lopez

B. the commerce power given to Congress by the Constitution

C. the reserved powers given to states by the Tenth Amendment

D. the use of categorical grants by the federal government

Answer 1

The best explanation for the major source of state government power during the period of dual federalism is:

C. the reserved powers given to states by the Tenth Amendment.

During dual federalism, which lasted from the founding of the United States until the New Deal, state governments maintained significant power and autonomy. The Tenth Amendment reserves powers not delegated to the federal government to the states, thereby serving as a cornerstone for state authority.
