📝 高級英語對話
Today, we'll explore the fundamental concepts of demand and supply in microeconomics. Demand refers to the quantity of a good that consumers are willing to purchase at various price points. Notice that when prices increase, demand typically decreases. This inverse relationship is crucial. Conversely, supply represents how much of a good producers are prepared to sell as prices fluctuate. When prices rise, the supply generally increases since businesses wish to maximize profits.
One significant aspect of demand is consumer preferences, which can shift over time due to trends or changes in income. A rise in consumer income might lead to an increase in demand for luxury goods, while basic necessities remain stable even with minor income changes.
On the flip side, supply can be influenced by production costs, technology, and supplier numbers. For example, if production costs rise due to more expensive raw materials, you may see a decrease in overall supply.
Interestingly, the equilibrium price is where demand meets supply. At this point, the amount of a good that consumers want to buy equals the amount that producers want to sell. Understanding this dynamic is essential for predicting market behavior. Market interventions, like price ceilings or floors, can disrupt this balance, leading to either shortages or surpluses.
In summary, grasping how demand and supply interact enables us to understand market economics better. The words demand and supply are not merely jargon; they are critical in decision-making processes for both consumers and businesses.

正確答案:
B
解釋:
The passage defines supply as 'how much of a good producers are prepared to sell as prices fluctuate,' confirming that option B is correct. Option A describes demand instead, and options C and D do not accurately represent the definition of supply.
