Class 9 Social Science Chapter 8 Very Short Answer Questions
Q6. What is the difference between a need and a want?
Answer:
A need is an essential requirement, such as food, water or shelter. A want is a desire for something beyond basic necessities, such as a luxury holiday.

Class 9 Social Science Chapter 8 Short Answer Questions with Solutions
Q10. Why does having more money not completely remove the problem of choice?
Answer:
Money is only one resource; time, land, water and skilled labour are also limited.
Wants can increase as income rises.
Resources can serve different purposes, so choosing one use means giving up another.
Even wealthy individuals and economies must decide how to allocate their resources.
Q11. A clothing enterprise receives orders for handmade embroidered outfits and large
quantities of identical uniforms. Why might it use different production methods for these orders?
Answer:
Embroidered outfits require skilled workers to create detailed, customised designs.
Identical uniforms are more suitable for machine-assisted production on a large scale.
The enterprise must also consider wages, machinery costs and available technology.
The nature of the product therefore influences the balance between labour and machinery.
Q12. What kinds of work can economists undertake outside classroom teaching?
Answer:
Economists can:
Advise governments on taxation and welfare spending.
Help enterprises improve efficiency and plan growth.
Analyse economic trends and possible risks.
Study investment choices and financial opportunities.
Their work uses data to compare alternatives and assess likely outcomes.
Q13. Observe the illustration. A school has one unused room and can afford only one of the two proposed uses. Identify the scarce resource, explain the choice and state the opportunity cost if the school selects the reading room.
Answer:
Scarce resources: The available room and the school’s limited funds.
Choice: The school must decide which facility to create because it cannot provide both with its existing resources.
Opportunity cost: If the music room is the next-best alternative, choosing the reading room means giving up the benefits of the music room.
Class 9 Social Science Chapter 8 Long Answer Questions on Economic Choices
Q14. A workshop can produce the following combinations of notebooks and drawing pads using its available resources efficiently. Study the data and answer the questions.
a. What happens to drawing-pad production as notebook production increases?
b. What is the opportunity cost of moving from Q to R?
c. What is the opportunity cost of moving from R to S?
d. What do these plans show about scarcity and choice?
Answer:
a. Drawing-pad production falls because the workshop transfers resources towards making more notebooks.
b. Moving from Q to R produces 20 additional notebooks but reduces drawing pads from 70 to 50. The opportunity cost is 20 drawing pads.
c. Moving from R to S produces 20 additional notebooks but reduces drawing pads from 50 to zero. The opportunity cost is 50 drawing pads.
d. The plans show that:
Available resources limit total production.
Increasing one product requires sacrificing some of the other.
Different production plans involve different trade-offs.
Efficient resource use does not remove the need to choose.
Q15. Observe the bakery illustration. Explain how the owner faces all three central economic questions. Suggest two factors that could influence the choice of production method.
Answer:
What to produce:
The owner must decide how much bread and how many cakes to make using the available ingredients, equipment and working time.
How to produce:
The owner must decide which tasks workers should perform by hand and which can use machinery.
For whom to produce:
The owner must consider the customers being served, such as a school buying bread in bulk or families ordering celebration cakes.
Two factors affecting the production method are:
Relative costs: The owner compares wages with the cost of buying and operating machinery.
Nature of the product: Standardised products may suit machines, while detailed decoration may require skilled labour.
Q16. Three economies organise production differently. In Economy X, a central authority sets major production targets. In Economy Y, private producers mainly respond to demand and supply. In Economy Z, private enterprises operate alongside public enterprises and government regulation. Identify each system and explain its main features.
Answer:
Economy X — Planned economy
A central government authority makes major economic decisions.
The government owns or controls most important resources and enterprises.
Production follows centrally determined targets.
Private enterprise and competition have a limited role.
Economy Y — Market economy
Individuals and private enterprises own most productive resources.
Demand and supply mainly guide production and prices.
Producers compete to attract customers.
Government still performs functions such as maintaining law and order and providing public infrastructure.
Economy Z — Mixed economy
Public and private enterprises both participate in production.
Market demand influences business decisions.
Government regulates activities and supports public welfare.
Public provision and private enterprise operate within the same economy.
These descriptions identify the main features of each system. Actual economies usually combine features rather than follow a completely pure model.
Make Your Chapter 8 Economics Answers More Precise
Use the Class 9 Social Science Chapter 8 important questions and answers to practise distinctions that are easy to miss.
Name the alternative given up: “Something is sacrificed” is incomplete. Identify exactly what the decision-maker loses.
Keep money and opportunity cost separate: A choice can have an opportunity cost even when no money changes hands.
Read production data in pairs: Compare the gain in one product with the loss in the other.
Match the economic question: Product and quantity concern what; production technique concerns how; distribution concerns for whom.
Avoid absolute statements: Labour-intensive does not mean no machines, and a market economy does not mean no government.

FAQs on Important Questions for Class 9 Social Science Chapter 8 Building Blocks in Economics: The Problem of Choice | 2026-27
1. Is Chapter 8 economics mainly about money?
No. It examines how people use limited resources to meet competing needs and wants. Money matters, but time, land, water, labour and machinery also create choices.
2. How do I identify opportunity cost in a question?
First identify the choice made, then find the next-best alternative that was given up. If several alternatives are available, opportunity cost refers to the best one forgone, rather than the total of every rejected option.
3. How do I calculate opportunity cost from a production table?
Compare two production plans. Find how much of one product is lost when more of the other is produced. If the question asks for cost per additional unit, divide the quantity sacrificed by the extra quantity gained.
4. Why does a Production Possibility Curve slope downwards?
With available resources being used efficiently, producing more of one good requires shifting resources away from the other. Output of the second good therefore falls, creating a downward-sloping relationship.
5. Can a production method use both workers and machines?
Yes. Labour-intensive and capital-intensive describe the relative importance of labour and machinery. A labour-intensive enterprise can use machines, while a capital-intensive factory still needs workers.
6. What should I practise in Vedantu’s Class 9 Social Science Chapter 8 important questions?
Practise identifying economic concepts in situations, calculating sacrificed output and explaining production decisions. Use the school-room and bakery questions to check whether you can apply ideas without relying on memorised wording.
7. How can I tell whether a situation shows a planned, market or mixed economy?
Look at who owns resources and makes major decisions. Central government control suggests a planned economy; decisions mainly guided by private enterprise and demand suggest a market economy. Public and private participation together indicate a mixed economy.
