Question 4.
What is the main criterion used by the World Bank in classifying different countries? What is the limitation of this criterion, if any?
Answer:
The World Bank classifies different countries on the basis of per capita income. The limitation of this criterion is that it does not take into account other indicators such as education and health levels of the people.
Question 5.
In what respects is the criterion used by the UNDP for measuring development different from the one used by the World Bank?
Answer:
The World Bank uses the criterion of per capita income while classifying the different countries. The UNDP uses the criteria of people’s level of education, people’s level of health and per capita income in the classification of different countries.
Question 6.
Why do we use averages? Are there are limitations to their use? Illustrate with your own examples related to development?
Answer:
We use averages for comparing the incomes of different countries. It is the total income of the country divided by the total population. This is also called the per capita income. The limitations are that this criterion does not take into account the levels of say education or health. For the purposes of overall development, one has to take into account total literacy rate as well as the life expectancy rate for comparing different countries.
Question 7.
Kerala with lower per capita income has a better human development ranking than Punjab. Hence, per capita is not a useful criterion at all and should not be used to compare states. Do you agree ? Discuss.
Answer:
Indeed per capita income in Punjab (? 26,000 in 2002-2003) is higher than what it is in Kerala (? 22,800 in 2002-2003), though punjab rates lower than kerala in literacy rate and in infant morality rate, We must remember that money cannot buy all the goods and services which we need. Thus income is not the only indicator of material goods and services. A pollution-free environment, and educational facilities help to attain developement.
Question 8.
Find out present sources of energy used by the people in India. What could be possibilities fifty years form now?
Answer:
In India, we use numerous sources of energy. These include sources such as coal, natural gases, water, petroleum. But fifty years from now, we may use sources such as solar, tidal, wind power. The conventional sources of energy are drying up.
Question 9.
Why is the isue of sustainability important for development.
Answer:
Sustainability is development with a view to make sure about the development of future. Nobody regulates the idea of development, but one has to maintain resources for the future generation. We have to leave things for others, and in good conditions. This is why that idea of sustainability is important.
Question 10.
“The Earth has enough resources to meet the needs of all but not enough to satisfy the greed of even one person”. How is this statement relevant to the discussion of development? Discuss.
Answer:
Greed has no limits. It can eat away everything the earth has. Our earth has a lot of it for everyone. Its resources are enough to meet the needs for the whole world, but it does not have enough for the greed of even one person. The earth is like a hen which gives eggs daily, everyday, and thus satisfies the need for everyone. But if we kill the hen, i.e., exploit the resources of the earth for our greed, we would have nothing left, for anyone.
Question 11.

- Gross enrolment ratio for three levels-The top country is sri Lanka (69), the bottom country is Pakistan (35).
- HDI rank in the world-The top country is Sri Lanka (93 the bottom country is Nepal (138).
Question 13.
The following table below shows the proportion of undernourished adults in India. It is based on a survey of various states in the country for the year 2001. Look at the table and answer the following questions

Describe in your own words.
