Exercise Solutions
Question 1
Development of a country can generally be determined by:
(i) its per capita income
(ii) its average literacy level
(iii) health status of its people
(iv) all the above
Answer
Correct Option: (iv) All the above
Explanation
Development is not measured only by income. Literacy level, health status, life expectancy, and quality of life are equally important indicators of development.
Question 2
Which neighbouring country has better performance in terms of human development than India?
Answer
Correct Option: (ii) Sri Lanka
Explanation
Sri Lanka has a higher Human Development Index, better literacy rate, and greater life expectancy compared to India.
Question 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?
Solution
Step 1: Total income of four families
= 5000 × 4
= Rs 20,000
Step 2: Total income of first three families
= 4000 + 7000 + 3000
= Rs 14,000
Step 3: Income of fourth family
= 20,000 − 14,000
= Rs 6,000
Answer
Correct Option: (iv) Rs 6000
Question 4
What is the main criterion used by the World Bank in classifying different countries? What are its limitations?
Answer
Main Criterion
The World Bank classifies countries based on Per Capita Income.
Limitations
- Ignores income inequality.
- Does not consider literacy.
- Does not consider health conditions.
- Ignores quality of life.
- Cannot measure social welfare completely.
Question 5
How is UNDP’s criterion different from the World Bank’s criterion?
Answer
The World Bank uses Per Capita Income only.
UNDP uses:
• Per Capita Income
• Health (Life Expectancy)
• Education (Years of Schooling)
Thus, UNDP provides a broader and more comprehensive measure of development.
Question 6
Why do we use averages? What are their limitations?
Answer
Why Averages Are Used
Averages help compare countries or groups having different population sizes.
Limitations
Averages hide inequalities.
Example
Country A and Country B may have the same average income, but in Country B most people may be poor while one person is extremely rich.
Question 7
Kerala, with lower per capita income, has a better human development ranking than Haryana. Do you agree that per capita income is not useful?
Answer
No.
Per capita income is useful because it shows economic status.
However, it is not sufficient alone because development also depends on:
• Education
• Health
• Public Facilities
• Life Expectancy
Hence, per capita income should be used along with other indicators.
Question 8
Find out the present sources of energy used in India. What could be the possibilities fifty years from now?
Answer
Present Sources
• Coal
• Petroleum
• Natural Gas
• Hydroelectricity
• Solar Energy
• Wind Energy
• Nuclear Energy
Future Possibilities
• Solar Power
• Hydrogen Fuel
• Advanced Nuclear Energy
• Offshore Wind Energy
• Biofuels
• Green Hydrogen Technology
Question 9
Why is sustainability important for development?
Answer
Sustainability ensures that resources remain available for future generations.
Without sustainability:
• Natural resources may get exhausted.
• Environmental pollution increases.
• Future development becomes difficult.
Therefore, development must be sustainable.
Question 10
“The Earth has enough resources to meet the needs of all but not enough to satisfy the greed of even one person.” Discuss.
Answer
The statement highlights the importance of responsible use of resources.
Resources are limited. If people exploit resources excessively for personal gain, future generations may suffer from shortages.
Therefore, resources should be used wisely and sustainably.
Question 11
List a few examples of environmental degradation.
Answer
• Air Pollution
• Water Pollution
• Deforestation
• Soil Erosion
• Global Warming
• Excessive Groundwater Extraction
• Industrial Waste Dumping
Question 12
For each item in Table 1.6, identify the country at the top and at the bottom.
Answer
Gross National Income
Top: Sri Lanka
Bottom: Nepal
Life Expectancy
Top: Sri Lanka
Bottom: Myanmar
Mean Years of Schooling
Top: Sri Lanka
Bottom: Pakistan
HDI Rank
Top: Sri Lanka
Bottom: Pakistan
Question 13
(i) Compare nutritional levels of Kerala and Madhya Pradesh.
Answer
Kerala has lower percentages of undernourished people than Madhya Pradesh.
Therefore, Kerala has a better nutritional status.
Answer (ii)
Many people remain undernourished because:
• Poverty
• Unequal food distribution
• Unemployment
• Lack of awareness
• Poor healthcare facilities
Even when food is available nationally, not everyone can access it equally.
