Explanation:

Macroeconomics is concerned with understanding economy-wide events such as the total amount of goods and services produced, the level of unemployment, and the general behaviour of prices.
Macroeconomics is a branch of economics that studies how an overall economy—the market or other systems that operate on a large scale—behaves. Macroeconomics studies economy-wide phenomena such as inflation, price levels, rate of economic growth, national income, gross domestic product (GDP), and changes in unemployment.
