Question

what is the primary focus of international economics as described in the passage?
the study of historical trade agreements
the interaction of nations through trade and investment
the impact of technology on manufacturing
the social policies of different countries
how might a country with a highly skilled labor force affect its economic strategy?
by focusing on manual labor
by specializing in technology or pharmaceuticals
by exporting raw materials
by rejecting international trade

Explanation:

International economics is centered around the economic interactions between nations. Trade and investment are key aspects of these interactions. A country with a highly - skilled labor force would likely leverage its human capital. Specializing in technology or pharmaceuticals (which often require skilled labor) is a logical economic strategy as it makes use of the available skilled workforce. Manual labor - focused strategies would not utilize the highly - skilled labor force effectively. Exporting raw materials is more associated with countries rich in natural resources rather than those with a skilled labor force. Rejecting international trade would limit the potential market for goods and services produced by the skilled labor force.

Answer:

For the first question: The interaction of nations through trade and investment.
For the second question: By specializing in technology or pharmaceuticals.
