Answer:
A macroeconomic factual question.
Step-by-step explanation:
Macroeconomics is the branch of the economics which deals with behavior, structure, performance, and the decision-making of the economy as a whole. This includes regional economies, national economies, and global economies.
Thus, asking about the average annual level of inflation is a factual question which comes under macroeconomics as it deals with the calculation of performance and behavior of the levels of inflation.
