Answer to Question 1

A tradeoff is a constraint or limit that forces giving up one thing in exchange for something else. When resources are fully employed, a country operates on its PPF. Any movement from one point to another point along the PPF requires the country to make a tradeoff between the two goods because one good is given up to get some other good. A free lunch occurs when some resources are not being used or not being used in their most productive way. When a country operates inside its PPF and moves toward its PPF choosing a different combination of goods, the country enjoys a free lunch. It does not face a tradeoff.
