The part of the economy controlled by the government, e.g., state health and education services, emergency services, and national defense.

• A. Public corporations
• B. Public sector
• C. Stock Exchange
• D. Private sector

Answer: (B)

This item tests understanding of the part of the economy that is controlled by the government. The public sector includes government-owned or government-controlled organizations and services that provide essential functions for society, funded by taxation. Examples like health and education services, emergency services, and national defense are typical public sector activities because they are run or financed by the government rather than by private individuals or companies. Public corporations are part of the public sector when they are government-owned, but the public sector as a whole covers more than just those enterprises. In contrast, the Stock Exchange serves as a market for buying and selling shares and is driven by private firms and investors, not government control, and the private sector consists of businesses owned by private individuals or groups.
