ITQ 3Classification
Classify the given occupations under primary, secondary and tertiary sectors.
Answer:
Note: Some activities may appear mixed in real life. For example, a milk vendor sells milk, so the activity is classified as tertiary service, while dairy farming itself belongs to the primary sector.
| Primary Sector | Secondary Sector | Tertiary Sector |
|---|---|---|
| Flower cultivator | Tailor | Milk vendor |
| Fishermen | Basket weaver | Priest |
| Gardener | Workers in match factory | Courier |
| Bee-keeper | Potter | Moneylender |
| — | — | Astronaut |
| — | — | Call centre employee |
Note: Some activities may appear mixed in real life. For example, a milk vendor sells milk, so the activity is classified as tertiary service, while dairy farming itself belongs to the primary sector.
ITQ 4School Classification
Students in a school are often classified into primary and secondary or junior and senior. What is the criterion used? Is this useful?
Answer:
The criterion used is usually the age group or class level of students. It is useful because students of similar age and learning level can be taught suitable subjects, activities and methods. However, it is not perfect because students may differ in ability, interest, pace of learning and maturity even within the same group.

ITQ 5GDP
What does the history of developed countries indicate about shifts between sectors?
Answer:
The history of developed countries shows that, in the early stage of development, the primary sector was most important. Later, with industrialisation, the secondary sector became important. In the last hundred years, the tertiary or service sector has become dominant in developed countries in terms of total production and employment.

Why is the tertiary sector becoming so important in India?
Answer:
The tertiary sector is becoming important in India because:
1. Basic services like hospitals, schools, banks, transport and communication are required in a developing country.
2. Development of agriculture and industry increases the demand for services such as transport, trade and storage.
3. Rising income creates demand for services like tourism, shopping, restaurants and private education.
4. New services based on information technology, software, call centres and digital communication are growing rapidly.

4Short Answer
What is GDP? Why are only final goods and services counted while calculating GDP?
Answer:
GDP or Gross Domestic Product is the value of all final goods and services produced within a country during a particular year.
Only final goods and services are counted because the value of intermediate goods is already included in the value of final goods. If intermediate goods are counted separately, the same value will be counted more than once. This is called double counting.

7Long Answer
How are the three sectors of the economy interdependent? Explain with examples.
Answer:
The primary, secondary and tertiary sectors are interdependent because each sector needs the support of the others.
The primary sector supplies raw materials to the secondary sector. For example, farmers produce sugarcane, which is used by sugar mills to produce sugar. Cotton grown by farmers is used by textile mills to make cloth.
The secondary sector supplies tools, machines and goods to the primary sector. For example, farmers need tractors, pumpsets, fertilisers and machines produced by industries.
The tertiary sector supports both primary and secondary sectors through services such as transport, banking, storage, communication, trade and insurance. For example, goods produced in factories must be transported to markets. Therefore, all three sectors depend on one another for production, distribution and consumption.

8Long Answer
Why does the primary sector continue to employ the largest number of workers even though its share in GDP has declined?
Answer:
The primary sector continues to employ the largest number of workers because many people in India still depend on agriculture for livelihood. However, the share of agriculture in GDP has declined because the secondary and tertiary sectors have grown faster in production value.
Another reason is disguised unemployment in agriculture. More people work on farms than actually needed. If some workers are removed, total production may not fall. This means many agricultural workers are underemployed. Due to lack of enough jobs in industries and services, people continue to remain dependent on agriculture even when their productivity is low.

9Long Answer
Workers are exploited in the unorganised sector. Do you agree with this view? Give reasons.
Answer:
Yes, workers are often exploited in the unorganised sector. They usually receive low wages and do not get regular employment. There is no job security, paid leave, medical benefit, provident fund or pension. Workers may have to work for long hours in unsafe conditions. Rules and regulations are often not followed by employers.
Many workers in the unorganised sector are poor and have no other employment option, so they accept unfavourable conditions. Examples include casual labourers, street vendors, domestic workers, construction workers and small workshop workers. Therefore, they need protection through fair wages, social security, health facilities, education, legal support and government schemes.

10Long Answer
How can workers in the unorganised sector be protected?
Answer:
Workers in the unorganised sector can be protected through the following measures:
1. Government should ensure minimum wages and regular payment.
2. Workers should get social security benefits such as health insurance, pension and accident insurance.
3. Employment should be made more secure through legal protection.
4. Working conditions should be improved, especially in small factories and construction sites.
5. Farmers and small producers should get cheap credit, seeds, fertilisers, storage facilities and fair prices.
6. Casual workers should get support through government employment schemes.
7. Education and skill training should be provided to improve employment opportunities.

11Long Answer
Explain the role of the public sector in the economy.
Answer:
The public sector plays an important role in the economy because many essential services cannot be left only to private companies. The government provides services such as education, healthcare, roads, bridges, railways, electricity, irrigation, drinking water, sanitation and public distribution.
The public sector also spends on large projects that require heavy investment and long-term planning. It supports poor and weaker sections through subsidies, ration shops, scholarships, employment schemes and welfare programmes. Since private companies mainly work for profit, the public sector is needed to ensure social welfare, equality and balanced development.

Important Concepts
Concept 1Final Goods
What are final goods and intermediate goods?
Answer:
| Final Goods | Intermediate Goods |
|---|---|
| Goods that reach the final consumer and are not used for further production. | Goods that are used to produce other goods and services. |
| Their value is counted in GDP. | Their value is not counted separately in GDP. |
| Example: Biscuits bought by consumers. | Example: Wheat and flour used to make biscuits. |
Concept 2Disguised Unemployment
What is disguised unemployment? Explain with an example.
Answer:
Disguised unemployment is a situation where more people are engaged in an activity than actually required. Even if some people are removed from the work, total production does not fall.
Example: Suppose five members of a family work on a small farm, but the work can be done by only three people. The extra two people are disguisedly unemployed because their contribution is not adding to production.

Concept 3Mahatma Gandhi NREGA
How does MGNREGA help in creating employment?
Answer:
Mahatma Gandhi National Rural Employment Guarantee Act provides guaranteed wage employment to rural households whose adult members volunteer to do unskilled manual work. It helps reduce rural unemployment and underemployment. The work often includes building roads, ponds, canals, water conservation structures and other public assets. It also increases rural income and creates useful infrastructure.
