Question

Read a quote from the US Constitution.

The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved for the States respectively, or to the people.

Which type of powers does this quote describe?

powers held by the states alone
powers implied within the US Constitution
powers clearly identified for the federal level

Answer 1

powers held by the states alone

This is the Tenth Amendment—reserved powers are those not delegated to the federal government nor prohibited to the states, and thus remain with the states (or the people).
