Identify which of the following is not a microeconomic question.

A. Why is international trade increasing?

B. Why do athletes earn more than checkout clerks?

C. Why are the fish stocks in the Atlantic ocean being depleted?

D. Why are libraries funded by the government?

None of these are microeconomic questions. Microeconomics is the subcategory of economics that deals with choices made by individuals, households, and businesses. The issues listed in this question are all macroeconomic because they all deal with the economy as a whole, or questions that affect the entire society. Some of them actually affect more than one country.
