a. Sketch a graph of a production possibility frontier with environmental quality on the horizontal axis, measured by the percentage reduction of gunk, and with the quantity of economic output on the vertical axis.

b. Which choices display productive efficiency?
How can you tell?

c. Which choices show allocative efficiency? How can you tell?

d. In the choice between K and L, can you say which one is better and why?

e. In the choice between K and N, can you say which one is better, and why?
