Answer:
- production of X good
- increase
Step-by-step explanation:
Production of good X over production of good Y (PX / PY) represents the opportunity cost of producing good X instead of good Y. The lower the ratio, the lower the opportunity cost. A lower opportunity cost results in a comparative advantage in the production of good X.
If the country starts to trade it will need to produce more of good X in order to exchange for other goods.
