Question

Given the data in the chart, over which country does the United States have a comparative advantage in oil production?

Answer 1

The answer is A because Canada shows the most valuable amount of oil that produces. 

Answer 2

The correct answer is A. The United States have an advantage over Canada in oil production, due to the fact that  less work hours are needed to be able to produce it. This gives a significant advantage since it increases the availability of oil in one country respect to the other  (in the United States it is easier to find oil than in Canada, so it would take less  time to produce it).
