Final answer:
To determine how much France needs to give up to gain from trade in tomatoes or green beans, the concept of opportunity cost and comparative advantage must be analyzed, which requires more specific data. Absolute advantage is defined by a country's higher productivity for a good compared to another country.
Step-by-step explanation:
To determine how much France would have to give up in terms of tomatoes to gain from trade, and how much it would have to give up in terms of green beans, we would need to analyze the concept of opportunity cost within the context of comparative advantage. The data provided in the question, however, is not sufficient to calculate the exact amount. In general, for France to gain from trade, it must give up the production of a certain quantity of one good (in this case, tomatoes or green beans) which it could have produced at a lower opportunity cost relative to another country. The amount given up is the opportunity cost of specializing in the production of the other good which it can produce more efficiently. If we were comparing France's production capabilities with those of another country, we would look for the good where France has a lower opportunity cost; France would specialize in producing that good while trading for the other.
The principle of absolute advantage refers to a country's ability to produce more of a good using the same amount of resources as another country. To identify which country has the absolute advantage in green beans or tomatoes, we would compare the productivity levels of each country in producing these goods. The country that can produce a greater quantity of a good with the same resources has an absolute advantage in that good.
