William faces the production possibilities frontier located on your left. He can only choose between studying for his classes or do debate research. If he only concentrates on his academics then he will produce 12 "study units" and produce no "debate units". If he only concentrates on debate then he will produce 12 "debate units" and produce no "study units". Lets assume that William is a one-person economy. Graphically show William's production possibilities frontier. Debate should be on the vertical axis.

Label four points on the graph: (A) a point inside the PPF; (B) a point on the PPF where debate is more valued than studying; (C) a point on the PPF where studying is more valued than debate; (D) a point outside the PPF
