2. Question 1: Scarcity | 第1题：稀缺性

Question: Which of the following best defines the economic problem of scarcity?

问题：以下哪项最能定义经济中的稀缺性问题？

A. There are not enough jobs for everyone. (工作岗位不足)

B. Resources are limited while human wants are unlimited. (资源有限而人类欲望无限)

C. Money is unevenly distributed. (金钱分配不均)

D. Governments cannot print unlimited currency. (政府无法无限印钞)

Correct Answer: B. Scarcity exists because our resources (land, labour, capital, enterprise) are finite, but our desire for goods and services is infinite. This is the basic economic problem that forces us to make choices. Option A relates to unemployment, C to income distribution, and D to money supply, none of which capture the core definition.

正确答案：B。稀缺性的存在是因为我们的资源（土地、劳动、资本、企业家才能）是有限的，但对商品和服务的欲望是无限的。这一基本经济问题迫使我们做出选择。选项A涉及失业，C涉及收入分配，D涉及货币发行，都不是稀缺性的核心定义。

3. Question 2: Opportunity Cost | 第2题：机会成本

Question: You have £10 to spend. You can buy either a book or a cinema ticket. If you buy the book, what is the opportunity cost?

问题：你有10英镑可以花，你可以买一本书或一张电影票。如果你买了书，机会成本是什么？

A. The £10 you spent. (你花掉的10英镑)

B. The book. (那本书)

C. The enjoyment of reading the book. (阅读该书带来的享受)

D. The cinema ticket and the experience of watching the film. (电影票及观影体验)

Correct Answer: D. Opportunity cost is the next best alternative forgone. By choosing the book, you give up the cinema ticket and the benefit it would have brought. The money itself is not the opportunity cost; it is what that money could have purchased. This question often tricks students into selecting the amount spent, so distinguish carefully.

正确答案：D。机会成本是被放弃的次优选择。当你选择买书时，你放弃了电影票及其带来的观影享受。金钱本身并非机会成本，机会成本是用这笔钱能购买的下一个最佳选项。此题常被误解为花费的金额，需要注意区分。

4. Question 3: Factors of Production | 第3题：生产要素

Question: A farmer uses a tractor, hires workers, and grows wheat on her land. Which factor of production does the tractor represent?

问题：一位农民使用拖拉机、雇佣工人并在她的土地上种植小麦。拖拉机代表哪种生产要素？

A. Land

B. Labour

C. Capital

D. Enterprise

Correct Answer: C. Capital refers to man-made goods used to produce other goods and services. Tractors, machinery, and tools are physical capital. Land is the natural resource (the earth where wheat grows), labour is the human effort, and enterprise is the entrepreneur who organises the other three factors. Classifying factors of production is a foundational skill; memorise concrete examples for each category.

正确答案：C。资本是指用于生产其他商品和服务的人造物品。拖拉机、机器和工具属于实物资本。土地指自然资源（种植小麦的土地），劳动是人的努力，企业家才能是组织其他三种生产要素的企业家。生产要素的分类是基础考点，要牢记每个类别的实例。

5. Question 4: Law of Demand | 第4题：需求定律

Question: The price of apples falls from £2 to £1 per kg. According to the law of demand, what is likely to happen?

问题：苹果价格从每公斤2英镑降至1英镑。根据需求定律，很可能发生什么？

A. The supply of apples will increase. (苹果的供给会增加)

B. The quantity demanded of apples will increase. (苹果的需求量会增加)

C. The demand curve for apples will shift to the right. (苹果的需求曲线会向右移动)

D. Consumers' income will rise. (消费者的收入会提高)

Correct Answer: B. The law of demand states that, ceteris paribus, a fall in price leads to an increase in quantity demanded (a movement along the demand curve). Option C suggests a shift in demand, which would be caused by factors other than the price of apples, such as a change in taste or income. The distinction between 'quantity demanded' and 'demand' is critical.

正确答案：B。需求定律指出，在其他条件不变的情况下，价格下降会导致需求量增加（沿着需求曲线移动）。选项C表示需求曲线的平移，这通常由苹果价格以外的因素引起，比如口味或收入的变化。区分“需求量变化”（movement）和“需求变化”（shift）至关重要。

6. Question 5: Supply and Costs | 第5题：供给与成本

Question: A bakery finds a cheaper supplier of flour. What is the most likely effect on the supply of bread?

问题：一家面包店找到了更便宜的面粉供应商。这对面包的供给最可能产生什么影响？

A. Supply decreases, shifting the supply curve to the left. (供给减少，曲线左移)

B. Quantity supplied decreases. (供给量减少)

C. Supply increases, shifting the supply curve to the right. (供给增加，曲线右移)

D. No change in supply. (供给不变)

Correct Answer: C. Lower input costs reduce the cost of production, making it more profitable to supply bread at any given price. This shifts the entire supply curve to the right, indicating an increase in supply. It is not a movement along the curve because the change is due to a factor other than the price of bread.

正确答案：C。投入成本降低减少了生产成本，使得在任何给定价格下供应面包更有利可图。这会导致整条供给曲线向右平移，表示供给增加。这并非沿着曲线移动，因为变化是由面包价格以外的因素（生产成本）引发的。

7. Question 6: Production Possibility Curve (PPC) | 第6题：生产可能性曲线 (PPC)

Question: A country can produce two goods: guns and butter. The PPC shows the maximum combinations. If the country moves from point A (20 guns, 50 butter) to point B (30 guns, 30 butter), what is the opportunity cost of producing 10 more guns?

问题：一个国家可以生产两种商品：枪炮和黄油。生产可能性曲线展示了最大组合。如果该国从点A（20支枪，50块黄油）移动到点B（30支枪，30块黄油），那么多生产10支枪的机会成本是多少？

Correct Answer: 20 units of butter. The opportunity cost of 10 guns is the 20 butter that must be given up. This illustrates increasing opportunity cost, as resources are not equally efficient in producing both goods. The PPC is bowed outward. When solving such questions, divide the amount sacrificed by the amount gained.

正确答案：20单位的黄油。多生产10支枪的机会成本是必须放弃的20块黄油。这说明了机会成本递增的原理，因为资源在生产两种商品时的效率并不相同，导致生产可能性曲线向外突出。解答此类题需用放弃的数量除以获得的数量。

8. Question 7: Resource Allocation | 第7题：资源分配

Question: Explain why every economy must answer the three basic questions: 'What to produce?', 'How to produce?', and 'For whom to produce?'.

问题：解释为什么每个经济体都必须回答三个基本问题：“生产什么？”“如何生产？”“为谁生产？”

Sample Answer: Because resources are scarce, choices must be made. 'What to produce?' decides which goods and services to allocate resources to. 'How to produce?' concerns the production methods—labour-intensive or capital-intensive. 'For whom to produce?' addresses the distribution of output among members of society. These questions are fundamental to any economic system, whether market, planned or mixed.

参考答案：由于资源具有稀缺性，必须做出选择。“生产什么”决定将资源配置到哪些商品和服务上。“如何生产”涉及生产方式——是劳动密集型还是资本密集型。“为谁生产”解决产出在社会成员之间的分配问题。无论是市场经济、计划经济还是混合经济，这三个问题都是任何经济体系需要回答的根本问题。

9. Question 8: The Price Mechanism | 第8题：价格机制

Question: Describe how the price mechanism resolves the problem of excess demand in a market.

问题：描述价格机制如何解决市场中的超额需求问题。

Sample Answer: Excess demand occurs when the current price is below the equilibrium price, leading to a shortage. Consumers compete to buy the limited supply, which bids up the price. As the price rises, quantity supplied increases (law of supply) and quantity demanded decreases (law of demand) until equilibrium is restored where demand equals supply. This automatic rationing occurs without central planning.

参考答案：当市场价格低于均衡价格时，会出现超额需求，即短缺。消费者竞相购买有限的供给，从而推高价格。随着价格上升，供给量增加（供给定律），需求量减少（需求定律），直到需求与供给重新达到平衡。这种自动配给机制无需中央计划即可运行。

10. Question 9: Functions of Money | 第9题：货币的功能

Question: List and briefly explain three functions of money. Give an example for each.

问题：列出并简要解释货币的三种功能，每种功能各举一例。

Sample Answer: 1. Medium of exchange: Money is accepted in exchange for goods and services, eliminating the need for barter. Example: Using cash to buy a sandwich. 2. Store of value: Money can be saved and used in the future, though its value may be eroded by inflation. Example: Saving pocket money in a bank account. 3. Unit of account: Money provides a common measure of the value of different goods. Example: Comparing the price of a burger (£5) with a pizza (£7). 4. Standard of deferred payment: Money allows debts to be stated and settled. Example: Borrowing £50 from a friend and repaying later.

参考答案：1. 交换媒介：货币被普遍接受用于交换商品和服务，消除了物物交换的需求。例：用现金购买三明治。2. 价值储藏：货币可以储蓄以备将来使用，尽管其价值可能因通货膨胀而受损。例：将零花钱存入银行账户。3. 价值尺度：货币为不同商品的价值提供了统一的衡量标准。例：比较汉堡（5英镑）和披萨（7英镑）的价格。4. 延期支付标准：货币可用于记账和偿还债务。例：向朋友借50英镑而后归还。
