TRUE/FALSE

1. The market demand curve shows how the quantity demanded of a product, during a specified time period, changes as the price of that product changes.

2. The law of demand states that a lower price increases the amount of a commodity that people are willing to buy.

3. The demand curve depicts quantities demanded that have been gathered as prices have changed over time.

4. The quantity demanded in a market depends on many things, but the concept of elasticity focuses on the effect of changes in the price of the good.
