Brief Explanations:

2. In a market economy, supply is the quantity of a good or service that producers are willing and able to offer for sale at various prices, while demand is the quantity that consumers are willing and able to buy at different prices. The interaction of supply and demand determines the equilibrium price and quantity.
3. Retraining is the process of teaching individuals new skills or updating their existing skills, often to adapt to changes in the job - market, new technologies, or different work requirements.
4. The business cycle refers to the fluctuations in economic activity around its long - term growth trend. The four stages are expansion (economic growth), peak (highest point of growth), contraction (economic decline), and trough (lowest point of decline).
