Now suppose a technological innovation in country X leads to a balanced growth while leaving the relative prices of food and clothing unchanged in the international market. Production of food in country X rises to 50 units and that of clothing rises to 25 units. If consumption of food, on the other hand, rises to 42 units, we can most reasonably conclude that the:A.

the size of country X’s trade triangle has increased.

country X’s willingness to trade declines.
