The main advantage of ________ is the ability to move out beyond previous resource and production constraints.

A) absolute advantage
B) trade barriers
C) trade between two countries
D) export subsidies

The main advantage of trade between two countries is that it allows both countries to move beyond their own resource and production constraints by specializing in the production of goods for which they have a comparative advantage and trading them for other goods. This enables countries to consume more than they would be able to produce on their own.
