Is this a shift of the demand curve or a movement along it? Explain your reasoning.\n\n**Answer:** It is a movement along the demand curve. The increase in quantity demanded was caused by a change in the good's *own price*, not by an external factor. A shift would require a change in income, tastes, substitutes, or population.\n\n---\n\n**Question 4 (Application):** The price of tea falls sharply. Coffee is a substitute for tea. What happens to the demand curve for coffee, and why?\n\n**Answer:** The demand curve for coffee shifts to the left (demand decreases). Because tea is a substitute, consumers switch to the now-cheaper tea, so less coffee is demanded at every price. Since coffee's own price didn't change, this is a shift of the whole curve rather than a movement along it.",
