Question 38

The supply curve for ice cream shifts to the left.

The decrease in the supply of cream, which is the primary input for ice cream production, leads to a leftward shift in the supply curve for ice cream. This shift indicates that at every price level, less ice cream is available due to the reduced availability of cream.

A) Shifts to the right

This option is incorrect because a rightward shift in the supply curve would indicate an increase in the supply of ice cream. However, the decrease in cream supply results in a reduced ability to produce ice cream, thus shifting the supply curve in the opposite direction.

B) Supply remains the same, and there is a movement up the curve

This option is also incorrect. A movement up the curve implies an increase in price due to higher demand or reduced supply of ice cream, but it does not account for the decrease in cream supply affecting the overall production. Therefore, the supply of ice cream does not remain the same.

C) Supply remains the same, and there is a movement down the curve

This option is incorrect as well. A downward movement along the supply curve suggests that the quantity supplied remains unchanged while the price decreases, which contradicts the situation where a lack of cream would lead to a reduction in the quantity of ice cream produced.

D) Shifts to the left

This option is correct, as it accurately reflects the impact of the decreased cream supply on ice cream production. With less cream available, producers are unable to make as much ice cream, leading to a leftward shift in the supply curve.

Conclusion

The correct answer is D, as the leftward shift of the supply curve for ice cream directly correlates with the decrease in cream availability. All other options fail to recognize the fundamental relationship between input supply and production capacity, leading to misconceptions about how supply curves respond to changes in resource availability.
