Q. Which of the following statements best describes the costs of international trade?
选项：
A.Countries without an absolute advantage in producing a good cannot benefit significantly from international trade. B.Resources may need to be allocated into or out of an industry and less-efficient companies may be forced to exit an industry, which in turn may lead to higher unemployment. C.Loss of manufacturing jobs in developed countries as a result of import competition means that developed countries benefit far less than developing countries from trade.解释：
B is correct. Resources may need to be reallocated into or out of an industry, depending on whether that industry is an exporting sector or an import-competing sector of that economy. As a result of this adjustment process, less-efficient companies may be forced to exit the industry, which in turn may lead to higher unemployment and the need for retraining so that displaced workers may find jobs in expanding industries.
资源可能需要重新分配到一个行业或从该行业调出，这取决于该行业是该经济的出口部门还是进口竞争部门。由于这一调整过程，效率较低的公司可能被迫退出该行业，这反过来又可能导致更高的失业率和需要再培训，以便流离失所的工人可以在扩大的行业中找到工作。
