### Understanding Price Elasticity of Demand**10. The price elasticity of demand for any good must be less than or equal to zero unless:** a. the good is a necessity. b. the good is a Giffen good. c. the good is a substitute. d. the good is a luxury. **Explanation:**This question deals with the price elasticity of demand, which measures how the quantity demanded of a good responds to changes in its price. Normally, most goods have a negative price elasticity of demand, implying that an increase in price leads to a decrease in quantity demanded. However, certain exceptions and categories can affect this relationship, which include:- **Necessities:** These are goods that are essential for survival or well-being. For necessities, the demand is generally inelastic since people will buy them regardless of price changes, but they still adhere to the rule of non-positive price elasticity in typical scenarios. - **Giffen Goods:** These are a rare type of goods where an increase in price leads to an increase in the quantity demanded, violating the typical law of demand. This phenomenon usually occurs when the good is an inferior good and its price increase makes the consumer unable to afford better substitutes, forcing them to buy more of the good despite the price rise. - **Substitutes:** Goods that can replace each other. For such goods, when the price of one good rises, consumers might switch to its substitutes. - **Luxuries:** These are high-end goods that are not necessary but are desired by consumers. Luxuries can have varying elasticities based on consumers' discretionary income.This question and its answer options help understand the unique cases in the concept of price elasticity in economics.#### Additional Note:The background of the image shows part of a MacBook Air with a visible keyboard.
