Step-by-step explanation:
The sharp increase in the number of workers making goods for distant markets can be attributed to A) Expansion of industrial production for global trade.
Global trade and the force of globalization have led to an increase in competition from foreign producers. As international trade increases, it contributes to a shift in jobs away from industries where a country does not have a comparative advantage and towards industries where it does have a comparative advantage. This shift towards industries with a comparative advantage in global trade has led to an expansion of industrial production for global trade.
