Building Blocks in Economics Question and Answer
Q. What does economics deal with?
Ans – Economics deals with how people use limited resources to satisfy unlimited wants. It studies the production, distribution, and consumption of goods and services.
Q. What are the key questions in economics?
Ans – Economics mainly deals with three key questions:
What to produce? – Which goods and services should be produced?
How to produce? – Which methods and resources should be used for production?
For whom to produce? – Who will receive or consume the goods and services?
Q. How do different economic systems address these questions?
Ans – Different economic systems answer the three key questions in different ways:
Market economy: Demand, supply, and prices largely decide what, how, and for whom to produce.
Command economy: The government decides what to produce, how to produce, and who receives the goods and services.
Mixed economy: Both the market and the government play important roles in making these decisions.
NCERT Questions:-
1..Why do you think people’s wants keep changing over time? How does this affect production in an economy? Why cannot all our wants be satisfied?
Ans – People’s wants keep changing because of changes in tastes, technology, income, lifestyle, and new inventions.
Effect on production: Producers change and increase or decrease production according to people’s changing demands.
Why all wants cannot be satisfied: Human wants are unlimited, but the resources available to satisfy them—such as time, money, land, and raw materials—are limited. Therefore, choices and priorities are necessary.
2. ‘Human wants are unlimited and keep changing’. How do youthink this constant desire for more creates pressure on the environment? Can the fulfilment of wants and the extraction of resources be balanced?
Ans – Human wants are unlimited and keep changing due to new needs, technology, tastes, and lifestyles. This creates pressure on the environment because more goods require more natural resources, leading to deforestation, pollution, and resource depletion.
Yes, wants and resource extraction can be balanced through sustainable development—using resources wisely, reducing waste, recycling, and using renewable resources so that future generations can also meet their needs.
3. Can you think of a resource in your region that is scarce but used wastefully? How could it be managed better?
Ans – Water can be a scarce resource in a region and is often wasted through leaking taps, excessive use, and inefficient irrigation.
It can be managed better by repairing leaks, harvesting rainwater, using water-efficient irrigation, and avoiding unnecessary wastage. This would help conserve water for the future.
4. Which economic system—market, planned, or mixed—do youthink gives people the most freedom? Which economic system is best suited for promoting innovation? Why?
Ans – Market economy gives people the most freedom because individuals and businesses can make choices about what to buy, sell, and produce.
The market economy is also best suited for promoting innovation because competition and the desire for profit encourage producers to develop new products, technologies, and better methods of production.
5. Critically examine why pure economic systems rarely exist in
reality. Assess the limitations of such systems and justify why
a mixed economy is often considered a more practical and
effective approach in real-world contexts.
Ans – Pure economic systems rarely exist because real economies need to balance economic freedom, social welfare, and efficient use of resources.
Market economy: Encourages freedom, competition, and innovation, but may lead to inequality and neglect of public welfare.
Planned economy: Can focus on social welfare and equitable distribution, but may reduce individual freedom, competition, and innovation.
Mixed economy: Combines the strengths of both systems. Markets encourage efficiency and innovation, while the government provides public services, regulates markets, and supports weaker sections.
Therefore, a mixed economy is often more practical because it balances economic freedom with social welfare and government intervention.
6. A student has ₹100 and must choose between buying a notebook or saving the money for buying a tennis racket later. Which economic concept best explains this situation?a. Demand b. Opportunity cost c. Production d. Inflation
Ans – b. Opportunity cost.
The student has to choose between buying a notebook now and saving ₹100 for a tennis racket later. The value of the next-best option given up is called opportunity cost.
7. How does understanding opportunity cost improve the quality
of economic decision-making?
Ans – Understanding opportunity cost improves economic decision-making by helping people compare alternatives and choose the option that gives them the greatest benefit.
It makes us aware of what we give up when we make a choice, leading to more careful and efficient use of limited resources.
8. Can effective economic decisions be made without reliable data? Support your answer with an example.
Ans – No, effective economic decisions are difficult to make without reliable data because decisions depend on accurate information about resources, costs, demand, and benefits.
Example: A farmer needs reliable data about rainfall, crop prices, and water availability before deciding which crop to grow. Without accurate data, the farmer may choose an unsuitable crop and suffer a loss.
9. Analyse how a country’s present economic choices can shapeits long-term future. Why is it important to consider future consequences while making economic decisions today?
Ans – A country’s present economic choices can strongly influence its long-term future. Decisions about education, healthcare, infrastructure, natural resources, and technology can promote future growth and development.
It is important to consider future consequences because resources are limited and today’s choices may affect future generations. For example, investing in renewable energy today can support economic growth while protecting natural resources for the future.
10. Identify a news article from any newspaper of your choiceabout a product or commodity (such as vegetables, fruits, fuel, or electronics) where producers or companies are deciding how much to produce or supply. Write 2–3 sentences explaining the example you found and why the production decision was made.
Ans – Do it Yourself.
