Which of the following factors directly shifts the demand curve for a normal good rather than its supply curve? (Select all that apply.)

### Why this is right - **Consumer income** can change how much consumers can afford, especially for normal goods. - **Tastes, fashion, and preferences** affect consumers' willingness to buy. - **The price of a substitute** can redirect demand toward or away from the good. - **Season and climate** can affect demand for particular commodities. ### The concept Demand depends on more than a product's own price. The note represents demand as a function of own price, substitute prices, income, and tastes, and also discusses seasonal influences. A change in own price usually produces movement along a demand curve; a change in another determinant changes the curve's position. ### The other options - **The firm's production technology**: the note treats technology as a factor influencing supply, not as a direct demand determinant. ### Terms - **Normal good**: a good whose demand rises when consumer income rises, other things equal. ### Remember Own price moves you along demand; other demand determinants shift it.
