What term refers to an instrument with a standard accepted value used to facilitate exchange, such as currency?

• A. Monetary Policy
• B. Mediums of exchange
• C. Monopoly
• D. Monotheism

Answer: (B)

This question tests understanding of money’s function in trade: money serves as a medium of exchange, an instrument that most people accept in return for goods and services. Because everyone agrees to accept money, it makes buying and selling easier than barter, which requires a double coincidence of wants. When money has a widely accepted value, it also helps price goods and store value for future purchases, reinforcing its usefulness in everyday transactions. Currency is a classic example of this role. The other ideas don’t fit: monetary policy is about managing the money supply and interest rates, monopoly is a market structure with one seller, and monotheism is a belief system about God.
