Let's answer each statement step by step, with explanations: --- ### **1. Between points A and E, curve HH is unit elastic.** **Step 1: Understand what unit elastic means.** A supply curve is unit elastic if the percentage change in quantity supplied is equal to the percentage change in price (elasticity = 1). For a straight line passing through the origin, supply is unit elastic everywhere. **Step 2: Analyze curve HH between A and E.** Curve HH is a straight line passing through the origin (0,0), and both A and E lie on this curve. Therefore, for HH between these points, elasticity is 1 (unit elastic). **Final answer:** **True**. --- ### **2. Between points A and D, curve JJ is elastic.** **Step 1: Understand what it means for a curve to be elastic.** A supply curve is elastic if the elasticity is greater than 1, meaning a 1% increase in price results in a greater than 1% increase in quantity supplied. **Step 2: Analyze curve JJ between A and D.** Curve JJ is a vertical line, meaning quantity does not change as price changes. This means the elasticity is zero (perfectly inelastic), not elastic. **Final answer:** **False**. --- ### **3. Curve KK is less elastic between points A and C than curve II is between points A and D.** **Step 1: Compare elasticity between the two curves in the given sections.** - Curve KK is a horizontal line, meaning any change in price results in no change in quantity supplied (elasticity is infinite; perfectly elastic). - Curve II is a steep upward-sloping curve passing through the origin, so it is unit elastic everywhere. **Step 2: Assess which is less elastic.** Curve KK (perfectly elastic) is not less elastic than curve II (unit elastic); in fact, it is more elastic. **Final answer:** **False**. --- ## **Summary Table** | Statement | True | False | |---------------------------------------------------------------------------|------|-------| | Between points A and E, curve HH is unit elastic. | ✔ | | | Between points A and D, curve JJ is elastic. | | ✔ | | Curve KK is less elastic between points A and C than curve II is between points A and D. | | ✔ |
