Final answer:

Step-by-step explanation:
The subject matter of the question relates to the macroeconomy's overall health, considering three main objectives that most economic studies focus on: economic growth, low unemployment, and low inflation. These are foundational goals pursued within the field of macroeconomics, which deals with the economy as a whole, as opposed to microeconomics that examines individual markets and the decision-making process of individuals and firms. Macroeconomics involves the analysis of economic policies, trends, and their effects on these three critical aspects, which are vital indicators of a country's economic stability and prosperity.
