Final answer:
The question pertains to 12 Master Categories of Commodities, but the referenced information only covers the Eight Major Categories in the Consumer Price Index, which does not directly correlate with the master categories of all commodities.
Step-by-step explanation:
The student asked about the 12 Master Categories of Commodities. However, the information provided only details the Eight Major Categories in the Consumer Price Index (CPI), which measures the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. The CPI categories are:
- Food and beverages (e.g., breakfast cereal, milk, coffee)
- Housing (e.g., renter's cost of housing, bedroom furniture)
- Apparel (e.g., men's shirts and sweaters, women's dresses)
- Transportation (e.g., new vehicles, airline fares)
- Medical care (e.g., prescription drugs, physicians' services)
In addition to these, commodities such as dairy, meats, and produce can be found in other categorizations. Specific categories of commodities like autos, capital goods, consumer goods, and industrial supplies also play a role in trade and economics.
