NCERT TEXTUAL QUESTIONS WITH ANSWERS

Question 1. Explain the term ‘infrastructure’.
Answer. Infrastructure refers to the basic supporting structure which is built to provide different kinds of services in an economy. Infrastructural installations do not directly produce goods but help in promoting production activities in an economy. Examples of infrastructure are: transport, communication, banking, power etc.

Question 2. Explain the two categories into which infrastructure is divided. How are both interdependent?
Answer. There are two types of infrastructure: (a) economic infrastructure, (b) social infrastructure.
Economic infrastructure directly supports the economic system from inside. Examples are energy, transport and communication. Social infrastructure indirectly supports the economic system from outside. Examples are health, education and housing.
Economic and social infrastructure are complementary to each other. Economic infrastructure improves the qualityof economic resources and raises the production, but it cannot be possible until population is literate to use them efficiently. Thus, both of them are needed for the growth and development of the country.

Question 3. How do infrastructure facilities boost production?
Answer. The prosperity of a country depends directly upon the development of agricultural and industrial production. Agricultural production requires power, credit, transport facilities, etc.; the deficiency of which leads to fall in productivity. Industrial production requires machinery and equipment, energy, banking and insurance facilities, marketing facilities, transport services which include railways, roads and shipping and communication facilities etc. All these facilities help in raising agricultural and industrial productivity.

Question 4. Infrastructure contributes to the economic development of a country. Do you agree? Explain.
Answer. Infrastructure contributes to the economic development of a country and it is an important determinant of its growth and development. It raises productivity, induces investment in different areas of economic activity, raises size of the market, facilitates outsourcing and employment. Thus, it is an essential support system for the economic development of the country.

Question 5. What is the state of rural infrastructure in India?
Answer. A majority of people live in rural areas. The state of rural infrastructure in India is as follows:

1.  Rural women are still using bio-fuels such as crop residues, dung and fuel wood to meet their energy requirement.
2.  They walk long distances to fetch fuel, water and other basic needs.
3.  The census 2001 shows that in rural India only 56 per cent households have an electricity connection and 43 per cent still use kerosene. About 90 per cent of the rural households use bio-fuels for cooking.
4.  Tap water availability is limited to only 24 per cent of rural households. About 76 per cent of the population drinks water from open sources such as wells, tanks, ponds, lakes, rivers, canals, etc.
5.  Another study conducted by the National Sample Survey Organisation noted that by 1996, access to improved sanitation in rural areas was only 6 per cent.

Question 6. What is the significance of ‘energy’? Differentiate between commercial and non-commercial sources of energy.
Answer. Energy is a critical aspect of development process of a nation. It is essential for industries, agriculture and related areas like transportation of finished goods. It is also used for domestic purposes like cooking, lighting, heating, etc.
Difference between Commercial and Non-commercial Sources of Energy

Question 7. What are the three basic sources of generating power?

Question 11. How has the consumption pattern of energy changed over the years?
Answer. Pattern of energy consumption in India is as follows:

1. In India, different sources of energy are converted into a common unit ‘million tonne of oil equivalent’ (MTOE).
2. At present, commercial energy consumption is 65 per cent of total energy consumed in India.
3.  Goal has the largest share of 55 per cent, followed by oil at 31 per cent, natural gas at 11 per cent and hydro energy at 3 per cent.
4.  Non-commercial energy sources account for over 30 per cent of the total energy consumption.
5.  There is import dependence on crude and petroleum products, which is likely to grow to more than 100 per cent in the near future.
6.  Atomic energy is an important source of electric power. At present nuclear/atomic energy accounts for only 2.4 per cent of total primary energy consumption.

Question 12. How are the rates of consumption of energy and economic growth connected?
Answer. Energy is a critical aspect of development process of a nation. It is essential for industries, agriculture and related areas like transportation of finished goods. It is also used for domestic purposes like cooking, lighting, heating, etc. With economic growth, consumption of energy will rise.

Question 13. What problems are being faced by the power sector in India?
