Explanation:

Let's assume there are two countries, x and y.

X produces 10 cheese and 10 bottles of wine while Y produces 6 cheese and 3 bottles of wine. Country x has an absolute advantage in the production of wine and cheese because it produces higher quantities of both goods when compared to country y.

Country x has a comparative advantage in the production of wine because its opportunity cost (1) is lower than the opportunity cost of country y (2).

Country y has a comparative advantage in the production of cheese because its opportunity cost (1/2) is less than that of country x (1).
