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

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

During the period of dual federalism, which lasted from the founding of the United States until the New Deal in the 1930s, state governments held significant authority over a range of issues, and this power was primarily derived from the Tenth Amendment, which reserves powers not delegated to the federal government to the states.
