QUESTION 4 Use the PPC tables for Brazil and Argentina above to answer the question below. Assume that there is an increase in productivity within Brazil that affects wheat production. Indicate which of the answers below is a correct statement (i.e. select every correct response). Note that there is no partial credit on this question - you must get this question completely correct, or your answer is incorrect. the opportunity cost of producing cars in Brazil will decrease the opportunity cost of producing wheat in Brazil will increase the opportunity cost of producing cars in Brazil will increase the opportunity cost of producing wheat in Brazil will decrease the opportunity cost of producing cars in Brazil will not change O the opportunity cost of producing wheat in Brazil will not change QUESTION 5 Use the PPC tables for Brazil and Argentina above to answer the question below. If there is an increase in productivity within Brazil that affects wheat production, then what effect will this have on the comparative advantage of Brazil (i.e. relative to Argentina)? if the increase in productivity is large enough, this change in productivity could give Brazil a comparative advantage in both goods (i.e. both cars and wheat) if the increase in productivity is large enough, this change in productivity could cause Brazil to have no comparative advantage in either good (i.e. Argentina would have it in both goods) if the increase in productivity is large enough, this change in productivity could cause the comparative advantage of Brazil to switch from wheat to cars if the increase in productivity is large enough, this change in productivity could cause the comparative advantage of Brazil to switch from cars to wheat O this change in productivity will not affect the comparative advantage of BrazilQUESTION 3 Brazil and Argentina both produce cars and wheat, as per the PPC provided below. Brazil A B C D Quantity of Cars 0 24 54 60 Quantity of Wheat 40 24 4 0 Argentina W X Y Z Quantity of Cars 0 24 40 64 Quantity of Wheat 80 50 30 0
