Answer:
Positive but incorrect
Explanation:
Macroeconomics is a branch of economics that studies how an overall economy—the market 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.
On the contrary, Microeconomics is the part of economics concerned with individual units, such as a person, a household, a firm or an industry.
Therefore the statement, "Macroeconomics is the part of economics concerned with individual units such as a person, a household, a firm, or an industry." is incorrect.
Furthermore, a positive statement is a statement based on theories and facts, and can be proven WHILE a normative statement is a statement based on values, judgements and opinions, which makes it subjective.
Therefore the statement is positive but incorrect
