Is the increase in imports a positive or negative development for the United States? Choose one: A. Positive. U.S. consumers will be effectively wealthier now that air conditioning units are so cheap, and that gain will outweigh the losses to U.S. producers of air conditioning units. B. Positive. With international trade, cheaper products are always a good thing for everyone, so there are only winners and no losers in this scenario. C. Negative. More air conditioning units produced in Twinsylvania being sold is a good thing for Twinsylvania, but Twinsylvania's gain must mean a loss for its trading partner, the United States. D. Negative. U.S. manufacturers of air conditioning units will suffer heavy losses and consumers won't be significantly better off than before
