3. The following hypothetical production possibilities tables are for China and the United States. Assume that before specialization and trade, the optimal product mix for China is alternative B and for the United States is alternative U. LO20.2

a. Are comparative-cost conditions such that the two areas should specialize? If so, what product should each produce?
