Great job! Country A can produce a ton of diapers at a "cost" of 2 cases of baby food; for Country B the same ton of diapers "costs" only 1 case of baby food. Since Country B has the lower opportunity cost for producing diapers, it possesses the "Comparative Advantage" in diapers. Conversely, the cost for producing baby food is lower in Country A (1/2 ton of diapers) than for Country B (1 ton of diapers) so Country A possesses the "Comparative Advantage" in baby food.
