Final answer:
Comparative advantage is the ability to produce a good or service at a lower opportunity cost than others. In this case, Naboo has a comparative advantage in ship parts production, while Tatooine has a comparative advantage in lightsabers production.
Step-by-step explanation:
Comparative advantage is the ability of a country or individual to produce a good or service at a lower opportunity cost than another country or individual. It is based on the concept of opportunity cost, which is the value of the next best alternative forgone when a decision is made. In this case, the question is asking about the opportunity cost of producing ship parts and lightsabers in Naboo and Tatooine.
In Naboo, the opportunity cost of producing one more unit of ship parts is giving up a certain number of units of lightsabers. In Tatooine, the opportunity cost of producing one more unit of ship parts is also giving up a certain number of units of lightsabers. However, Tatooine has a comparative advantage in the production of ship parts because its opportunity cost of producing ship parts is lower than in Naboo.
Similarly, in Naboo, the opportunity cost of producing one more unit of lightsabers is giving up a certain number of units of ship parts. In Tatooine, the opportunity cost of producing one more unit of lightsabers is also giving up a certain number of units of ship parts. However, Naboo has a comparative advantage in the production of lightsabers because its opportunity cost of producing lightsabers is lower than in Tatooine.
