Question

1. which of the following is not a common shifter to the demand curve?

options: preferences, consumer income, future expectations, number of producers

Explanation:

To determine which is not a demand curve shifter, recall: Demand curve shifters relate to consumers (preferences, income, future expectations affect consumer demand). The number of producers affects the supply curve (as it relates to how much producers offer), not the demand curve.

Answer:

D. Number of Producers (assuming the options are labeled A - D with A: Preferences, B: Consumer Income, C: Future Expectations, D: Number of Producers)
