a. The PPC would shift outward on the fish axis, but would not change on the bread axis.

b. The PPC would shift outward equally along both the fish and the bread axes.

c.The PPC would shift inward on the the bread axis, but would not change on the fish axis.

d. The PPC would shift equally along both the fish and the bread axes.

If an economy can produce various combinations of food and shelter along a production possibilities curve (PPC), then if we increase the production of shelter along the PPC, which of the following is true?

  1. We also increase the production of food.
  2. We must decrease the production of food. This foregone food production represents the opportunity cost of the increase in shelter.
  3. We cannot change the production of food.
  4. The concept of opportunity cost does not apply to a PPC.
