Answer:
The answer is: b
Step-by-step explanation:
The question is essentially seeking to find out whether the United States (U.S) or China have an advantage in the manufacturing of aircraft or shirts. Comparative advantage is the ability of a person, company or country to perform a task more efficiently than other people, companies or countries. Comparative advantage is analysed by calculating opportunity cost. Opportunity cost is the foregone benefit that arises when one alternative is chosen instead of another.
U.S
If the U.S produces one aircraft, then the opportunity cost would be 5000 shirts (10,000 hours/ 2 hours). If the U.S produces one shirt, then the opportunity cost would be 0.0002 (2 hours /10,000 hours) of an aircraft.
China
If China produces one aircraft, then the opportunity cost would be 10,000 shirts (40,000 hours/ 4 hours). If China produces one shirt, then the opportunity cost would be 0.0001 (4 hours/40,000 hours) of an aircraft.
China has a comparative advantage in making clothes since the opportunity cost for lost shirts is higher (10,000). The U.S has a comparative advantage in aircraft production since the opportunity cost for lost aircraft manufacturing is higher (0.0002). Therefore, China should focus on producing shirts and export them to the U.S whereas the U.S should focus on manufacturing and exporting fleets of aircraft to China.
