When Both Exports and Imports Are Considered, the Major Advantage

When both exports and imports are considered, the major advantage of international trade is that it allows us to:

A) sample foreign products that many of us would otherwise never see.
B) ​consume a larger, more diverse quantity of goods and services at lower prices than would otherwise prevail.
C) ​share our technology and efficiency with less-developed countries that would otherwise never have the opportunity to observe modern goods and services.
D) ​maintain jobs for workers who would otherwise have little to do.
