Which of the following describes the tools, machines, and buildings used to produce goods and services?

• A. Labor
• B. Entrepreneurship
• C. Capital
• D. Productivity

Answer: (C)

The concept being tested is what capital means in production. Capital refers to the physical assets that enable production—tools, machines, and buildings. These are the assets used over time to produce goods and services, rather than the people working or the ideas driving the process. That’s why they’re described as capital goods: they persist through many production cycles and help generate output.

This differs from labor, which is the human effort and skills involved in making goods or delivering services. It also differs from entrepreneurship, which is about organizing, risk-taking, and innovating within the production process. Productivity, meanwhile, is a measure of how efficiently inputs are turned into outputs, not the assets themselves. So the description of tools, machines, and buildings used to produce goods and services corresponds to capital.
