Which of the following is an example of government's role of keeping order in society?

A. issuing paper money
B. operating a lottery
C. prohibiting bartering
D. taxing education
D.

The correct answer is C. prohibiting bartering.

To figure out the government's role in keeping order in society, we need to understand the options provided and determine which one aligns with this concept.

A. Issuing paper money: While this is a function of the government, it primarily serves economic purposes rather than maintaining order in society.

B. Operating a lottery: This is a government-run activity that generates revenue, but it is not directly related to maintaining order in society.

C. Prohibiting bartering: Bartering refers to trading goods or services without using money. By prohibiting bartering, the government ensures that economic transactions are conducted using a standardized currency, promoting stability, fairness, and preventing potential conflicts.

D. Taxing education: Taxing education is not directly related to maintaining order in society. While the government can collect taxes to fund public services, education is typically considered a way to enhance society rather than a means for maintaining order.

Therefore, the correct answer is C. prohibiting bartering, as it directly aligns with the government's role of keeping order in society.
