Cite three important reasons why nations trade.

What will be an ideal response?

First, specialization and trade among nations is advantageous because the world’s resources are not evenly distributed. To obtain resources or products that a nation does not have but that are desired by society requires trade with other nations. Second, the efficient production of different commodities necessitates different methods and combinations of resources. These different methods and combinations can be obtained through trade. Third, products vary in quality and in other ways. People prefer this variety, which often can only be obtained through imports.
