1. Development of a country can generally be determined by
Answer: d. all the above
2. Which of the following neighbouring countries has better performance in terms of human development than India?
Answer: b. Sri Lanka
3. Assume there are four families in a country. The average per capita income of these families is Rs 5000. If the income of three families is Rs 4000, Rs 7000 and Rs 3000 respectively, what is the income of the fourth family?
Answer: d. Rs 6000
(4000+7000+3000+x) ÷ 4 = 5000
14000+x = 5000 × 4
x = 20000-14000
x = 6000
4. What is the main criterion used by the World Bank in classifying different countries? What are the limitations of this criterion, if any?
Answer: World Bank uses the per capita income to classify different countries. The per capita income is calculated by dividing the total income of the country by the population of the country. For the year 2017, the countries with per capita income of US $12,056 per annum were declared rich countries and the countries with per capita income of US $ 955 or less are called low-income countries.
The limitations of the criterion are:
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 criterion used by UNDP is different from the one used by the World Bank because UNDP compares countries based on the educational level of the people, their health status and per capita income. This is in contrast with the method used by the World Bank because the World Bank only calculates the per capita income for measuring development.
6. Why do we use averages? Are there any limitations to their use? Illustrate with your own examples related to development.
Answer: We use averages because they are useful for comparing differing quantities of the same category. Different countries have a different population, so calculating the average helps in getting an estimated answer which can be used to compare different things at different levels. There are limitations of calculating averages because we cannot know the difference in the income of the people and the unfair distribution of income in a country or state.
For example, if we calculate the per capita income of two countries A and B with 5 people each, the salary of five people in country A is Rs.23,000, Rs.22,000, Rs.23,500, Rs.28,000 and Rs.25,000 and the income of people living in country B are Rs.1,50,000, Rs. 22,000, Rs.50,000, Rs.4000, Rs.2500. The average income of country A will be Rs.24,300, and that of country B will be Rs.45,700. This proves that the average of country B is higher than that of country A, and yet there is a disparity in the income distribution of country B and the income is evenly distributed in country A.
7. Kerala, with lower per capita income has a better human development ranking than Haryana. Hence, per capita income is not a useful criterion at all and should not be used to compare states. Do you agree? Discuss.
Answer: No, I do not agree with the statement that per capita income is not a useful criterion at all. Kerala, with lower per capita income has a better human development ranking than Haryana because, human development ranking is determined using a combination of factors such as health, education, and income. Kerala, with lower per capita income, has a better human development ranking than Haryana. This is true because the literacy rate, infant mortality rate, healthcare facilities, etc. are better in Kerala in comparison to Haryana. The per capita income is only calculated by calculating the average income of the state, irrespective of any other factor.
8. Find out the present sources of energy that are used by the people in India. What could be the other possibilities fifty years from now?
Answer: The present sources of energy used by people in India include firewood, coal, petroleum, crude oil and natural gas. The other possibilities fifty years from now can be using solar energy and wind energy as a source for various energy forms. This is because the current usage of sources of energy may result in the loss of these resources for future generations.
9. Why is the issue of sustainability important for development?
Answer: Sustainable development refers to the kind of development in which the present generation utilise the resources without compromising the need of present generation. The issue of sustainability is important for development because if the natural resources are not used carefully, they may not be available for future generations. The depleting resources of a country may ultimately result in a lack of development of the country.
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: Development not just depends on the economic factors of a country, but is also dependent on resources that are available for the people of a country to use. The statement: “The Earth has enough resources to meet the needs of all but not enough to satisfy the greed of even one person” is completely relevant in terms of the development of a country because natural resources are non-renewable resources. It is the responsibility of the people to use them only to meet their needs and not to satisfy their greed. If natural resources are not used wisely now, the future generations may not be able to use them for their needs, which will result in the downfall of development of a country.
11. List a few examples of environmental degradation that you may have observed around you.
Answer: A few examples of environmental degradation that we can observe around us are:
The increased pollution in the environment has resulted in global warming and depletion of glaciers and the atmospheric conditions.
12. For each of the items given in Table 1.6, find out which country is at the top and which is at the bottom.
Answer: As per table 1.6, Sri Lanka tops in all the four categories. It has the highest Gross National Income, Life expectancy at birth, mean years of schooling of people aged 25 and above and HDI rank in the world. Nepal has the lowest Gross National Income among the given countries. Pakistan has the least Life Expectancy at birth and ranks the lowest HDI rank in the world among the given countries. Mean years of schooling of people aged 25 and above is the lowest for Myanmar and Nepal.
