Final answer:
Macroeconomics is indeed the study of the economy as a whole, focusing on broad issues like production growth and unemployment, and is complemented by microeconomics, which focuses on individual economic agents.
Step-by-step explanation:
The statement that macroeconomics is the study of the economy as a whole is true. This branch of economics looks at broad issues that impact the entire economy, such as the growth of production, unemployment levels, inflation rates, government spending and deficits, as well as trade balances involving exports and imports. In contrast, microeconomics focuses on the actions and decisions of individual agents, like households and firms. The two are not isolated but rather are complementary perspectives that provide a complete understanding of economic activities and policies.
