Answer:
An example to question A would be:
Section 8 permits Congress to coin money and to regulate its value. Section 10 denies states the right to coin or to print their own money. The framers clearly intended a national monetary system based on coin and for the power to regulate that system to rest only with the federal government.
An example to question B would be:
The federal authority is limited to restricting the movement of anyone who "is reasonably believed to be infected with a quarantinable communicable disease." It's not at all certain how that would apply to large groups of people. Under the law, there is no explicit statutory authority for a blanket federal interstate quarantine, only for the isolation of individual people deemed infected.
So, B would not be federal.
