Sometimes when the state and federal governments have concurrent authority, the federal government can decide to regulate that a
liberstina [14]

Answer:

<h3>The correct answer would be the doctrine of federal preemption.</h3>

Explanation:

Clause II of Article VI of the U.S. Constitution states that federal law is the "supreme law of the land." It implies that every judge of state and other courts must follow the federal laws of the Constitution.

This clause, often termed as Supremacy Clause, allow federal laws to preempt state laws, even when both the state and federal governments have concurrent authority over a particular subject.

bulgar [2K]

Answer:

Emily's opportunity cost of producing 1 milkshake is 1 ice cream sundae.

Ben's opportunity cost of producing 1 milkshake is​ 0.5 ice cream sundae.

Explanation:

Both Emily and Ben own an ice cream parlor.

In an hour Emily can produce 40 milkshakes or 40 ice cream sundaes.

Emily's opportunity cost of producing a milkshake is

= \frac{What\ is\ sacrificed}{What\ is\ gained}

= \frac{40}{40}

= 1 ice cream sundae

In an hour Ben can produce 20 milkshakes or 10 ice cream sundaes.

Ben's opportunity cost of producing a milkshake is

= \frac{What\ is\ sacrificed}{What\ is\ gained}

= \frac{20}{10}

= 0.5 ice cream sundae

We see that Ben has a lower opportunity cost of producing milkshake, so we can say that he has a comparative advantage in producing milkshake.
