Using the graph, complete the table that follows by indicating whether each statement is true or false.
Statement
True
False
Between points A and E, curve HH is perfectly inelastic.

Curve JJ is less elastic between points A and D than curve KK is between points A and C.

Between points A and C, curve KK is elastic.

To determine the truth of each statement based on the description of the graph, we need to analyze the elasticity of the supply curves (HH, II, JJ, and KK) based on their relative slopes. Here's a breakdown of each statement:

### 1. **Between points A and E, curve HH is perfectly inelastic.**

- A perfectly inelastic supply curve means that the quantity supplied does not change regardless of price changes. A perfectly inelastic curve is vertical.
- If curve HH is vertical between points A and E, this statement is **true**.
- If HH is not vertical, this statement is **false**.

**Conclusion**: Based on the description of the graph, if HH is vertical, the statement is **true**. Otherwise, it is **false**.

### 2. **Curve JJ is less elastic between points A and D than curve KK is between points A and C.**

- Elasticity refers to how much the quantity supplied changes in response to price changes. A steeper curve is less elastic (more inelastic), while a

The following graph displays four supply curves (HH, II, JJ, and KK) that intersect at point A. Using the graph, complete the table that follows by indicating whether each statement is true or false: 1. Between points A and E, curve HH is perfectly inelastic. 2. Curve JJ is less elastic between points A and D than curve KK is between points A and C. 3. Between points A and C, curve KK is elastic.
