If a Hawaiian can produce 50 bushels of either potatoes or pineapples per acre, whereas an Idahoan manages just 3 bushels of pineapples or 30 bushels of potatoes per acre, then: (1) Idaho’s absolute drawbacks prevent gains from specialization and exchange. (2) The optimal division is if each is self adequate. (3) Both might gain from the specialization and exchange, with Hawaiian growing pineapples and replacing them for Idaho potatoes. (4) Hawaii is very close to Idaho for either side to gain.
Can someone please help me in finding out the right answer from the above question.
