Suppose South Africa produces two types of goods: agricultural and capital. The following diagram shows its current production possibilities frontier for barley, an agricultural good, and airplanes, a capital good.

Drag the production possibilities frontier (PPF) on the graph to show the effects of a breakout of avian flu that sickens millions of workers.

Note: Select either end of the curve on the graph to make the endpoints appear. Then drag one or both endpoints to the desired position. Points will snap into position, so if you try to move a point and it snaps back to its original position, just drag it a little farther.
