Question: Which of the following does the so-called elastic clause of the U.S. constitution allow? The federal government can exercise powers in areas in conflict with the rights guaranteed under the Tenth Amendment to the states. States have to recognize contracts, such as drivers' licenses, entered into in other states. States can refuse to enforce or recognize actions of another state if they violate the policy of that state. It only applies to activities of the state governments and not the federal government.
