The image shows a graph of price (in dollars) versus quantity (in units), with several labeled points (P, Q, R, S, V, W, X, Y, Z) and curves connecting them. Below the graph, there are statements about the elasticity of these curves, with a table to mark each statement as "True" or "False."

Elasticity in economics refers to the responsiveness of quantity demanded or supplied to changes in price. If a curve is perfectly inelastic, the quantity does not change despite changes in price, which typically occurs on a vertical line. When comparing elasticities between two points on different curves, a flatter curve tends to indicate higher elasticity (greater responsiveness to price changes), while a steeper curve is less elastic.

Let's analyze the three statements shown below the graph:

1. "Between points V and W, curve PP is perfectly inelastic."

   • A perfectly inelastic curve would be vertical, as it implies no change in quantity despite a price change. Looking at curve PP between points V and W, the curve does not appear to be vertical, so this statement is False.

2. "Curve RR is more elastic between points V and Y than curve QQ is between points V and X."

   • To compare elasticity, observe the steepness of the two curves. Curve RR between points V and Y appears steeper than curve QQ between V and X, which suggests that curve RR is less elastic than curve QQ in that range. Therefore, the statement is False.

3. "Between points V and X, curve QQ is inelastic."

   • A curve is inelastic if it is relatively steep, meaning quantity does not respond significantly to price changes. Curve QQ between points V and X seems steep, suggesting inelasticity. This statement is likely True.

Here are 5 related questions to expand on the topic:

1. What is the mathematical formula to calculate elasticity between two points on a demand curve?
2. How does elasticity affect revenue for a business?
3. What are the different types of elasticity in economics besides price elasticity of demand?
4. How would a perfectly elastic demand curve look like on this graph?
5. How can elasticity influence government policies like taxation?

Tip: Inelastic goods tend to have fewer substitutes and are necessities, meaning that consumers' quantity demanded doesn’t change much with price changes.
