Quiz: Introduction to Economics — 10 questions

1. What does the economy refer to?

A. The theory explaining how scarce resources affect decisions

B. The social science that analyzes consumer behavior

C. The system through which goods and services are produced and exchanged

D. The personal budget used by an individual household

Answer: (C)

Explanation

The economy is the system in which goods and services are produced, distributed, sold, and purchased. The social science that studies this system is economics, while the other choices describe narrower or different concepts.

2. Why must individuals, businesses, and governments make economic choices?

A. Human wants are limited while resources become easier to obtain.

B. Resources are limited while human wants are unlimited.

C. Goods are distributed equally while preferences remain identical.

D. Resources are unlimited while human wants remain stable.

Answer: (B)

Explanation

The scarcity principle exists because resources are limited or difficult to obtain while human wants are unlimited, requiring choices and priorities. The other options reverse or misrepresent the relationship between resource availability and human wants.

3. A city has a limited budget and must choose between repairing roads and expanding public transport. What economic consequence of scarcity does this situation demonstrate?

A. It creates a trade-off requiring the city to prioritize one use of resources.

B. It removes the need for choices because both projects serve public needs.

C. It shows that production and consumption are unrelated to resource limits.

D. It guarantees that the city can satisfy every desired improvement.

Answer: (A)

Explanation

Scarcity forces institutions to make trade-offs and seek efficient uses for limited resources, so the city must prioritize between competing projects. The other choices deny or ignore the need to allocate scarce resources.

4. According to the cost-benefit principle, when should an individual, business, or government take an action?

A. When the action produces no measurable economic effect

B. When the expected benefits are smaller than the costs

C. When the benefits are at least as great as the costs

D. When the costs and benefits cannot be compared reliably

Answer: (C)

Explanation

The principle recommends taking an action when its benefits equal or exceed its costs. An action with costs greater than benefits is not justified under this rule.

5. Which question is most clearly a microeconomic question?

A. How does inflation affect purchasing power across a country?

B. How does a higher price affect demand for coffee at one café?

C. How does monetary policy influence overall economic growth?

D. How does unemployment change during a national recession?

Answer: (B)

Explanation

Microeconomics examines decisions by individuals and businesses and their effects on specific markets, such as demand at one café. The other questions concern economy-wide outcomes studied in macroeconomics.

6. Which activity best illustrates economics rather than the economy itself?

A. Producing vegetables for sale in a local market

B. Distributing medicine through regional suppliers

C. Purchasing household goods from a retailer

D. Studying how scarcity influences the prices of goods

A. The hiring choice made by a single restaurant

B. The pricing decision of one clothing retailer

C. The effect of interest rates on the entire national economy

D. The demand for a particular brand of smartphone

Answer: (C)

Explanation

Macroeconomics studies large-scale outcomes and policies, including interest rates and their effects on the entire economy. Individual firms, workers, and product markets are the focus of microeconomics.

8. A policy concerning employment, industry, and national trade would most appropriately be described as what?

A. An economic policy because it concerns economic activity

B. An economic policy because it avoids using scarce resources

C. An economical policy because it limits household spending

D. An economical policy because it reduces resource use

Answer: (A)

Explanation

“Economic” is the appropriate adjective for matters involving trade, industry, money, business, and the economy. “Economical” refers to efficient or low resource use, not to economic activity as a subject area.

9. What is the likely economic outcome when an action’s benefits exceed its costs?

A. It can produce regret because resources are misallocated

B. It can create a gain and support economic growth

C. It creates a loss because benefits signal higher expenses

D. It has no positive or negative effect on the decision-maker

Answer: (B)

Explanation

When benefits exceed costs, the action can satisfy individuals and contribute to economic growth. The negative outcome is associated with costs exceeding benefits, while equal costs and benefits produce a neutral result.

10. Which sentence uses “economical” correctly?

A. The new factory created economic growth in the region.

B. The company reported economic changes in international trade.

C. The new car is economical because it uses little fuel.

D. The government announced economic reforms for businesses.

Answer: (C)

“Economical” describes something that uses few resources or uses them efficiently, such as a fuel-efficient car. The other choices use “economic” correctly because they refer to trade, business, or broader economic activity.
