In country A, a worker can produce 3 tons of wheat or 1 ton of steel. There are 125 workers in A. Calculate the point that PPF for A intersects the Wheat axis, i.e., the intercept. Select one: O a. 100 b. 125 C. 1 o d. 375 In country A, a worker can produce either 3 tons of wheat or 1 ton of steel. In country B, a worker can produce either 1 ton of wheat or 3 tons of steel. If they trade (voluntarily) with each other, the price of a ton of wheat must be Select one: a. between 1/3 ton and 1 ton of steel b. between 1/3 ton and 3 tons of steel c. less than 1 ton of steel d. between 1 ton and 3 tons of steel. Country A produces both wheat and steel, and it does not trade with any other country. People in that country always want to consume equal amounts of wheat and steel. One day someone in country A discovers how to grow more wheat using the same number of workers. As a result of this innovation, the consumption in A will change as follows Select one: a. they will consume more wheat, but the same amount of steel, compared to their consumption before the innovation. b. Since the innovation only increases the productivity of those who work in wheat production (but, not the steel production) their consumption levels will not change. c. they will consume more steel, but the same amount of wheat compared to their consumption before the innovation. d. they will consume more wheat and more steel, compared to their consumption before the innovation. The principle of comparative advantage does not provide answers to certain questions. One of those questions is Select one: a. Is it possible for specialization and trade to increase total output of traded goods? b. What determines the exact price at which trade takes place? O c. Is it possible for specialization and trade to benefit more than one party to a trade? d. Do opportunity costs play a role in people's decisions to specialize in certain activities
