Q1. Why do we use averages? Are there any limitations to their use? Illustrate with your own example related to development.
Ans: Averages are used to summarise data and make comparisons between different groups or populations. They provide a single representative value that helps understand general trends. However, averages have limitations:

In Country A: Two citizens have only a primary education or are illiterate, while the other two have doctoral or postgraduate degrees.
In Country B: All four citizens have graduate-level education. Although the average education level is the same in both countries, there are major differences:
Country A shows significant inequality in educational attainment, whereas Country B has more uniform education levels. This example demonstrates that averages do not reveal inequalities within populations.
Q2. List a few examples of environmental degradation that you may have observed around you.
Ans: Examples of environmental degradation include:
These examples show that environmental degradation is a widespread problem affecting many regions.

Q3. Differentiate between renewable and non-renewable energy resources. Find out the present resources of energy in India.
Ans: Renewable energy resources are naturally replenished and can be used repeatedly without depletion. Examples include:
In contrast, non-renewable energy resources are finite and will eventually be exhausted. Examples include:
India's present energy resources include:
These non-renewable resources are estimated to last for approximately 43 years at current rates of consumption. It is crucial to develop and adopt environmentally friendly alternatives.
Q3. (a) What does the Human Development Index (HDI) indicate? (b) By whom HDI is prepared?
Ans: (a) Human Development Index (HDI) is a composite index that measures a country's average achievements in three basic aspects of human development:
The HDI score ranges from 0 to 1, where 0 indicates the lowest human development and 1 indicates the highest. It assesses relative human development rather than absolute levels.
(b) The United Nations Development Programme (UNDP) has prepared the HDI since 1990.

Ans: The two main tools for comparing underdeveloped and developed countries are:
Q7. How does the National Development of a country depend on the availability of public facilities?
Ans: National development depends greatly on public facilities, which ensure equitable access to essential services, particularly for those who cannot afford private options. Important points are:
These public facilities are crucial for creating a more equal and developed society.
Q8. "The Earth has enough for everyone's needs but not for everyone's greed." Explain the need for sustainable development in the context of the above statement.
Ans: The statement "The Earth has enough for everyone's needs but not for everyone's greed" emphasises that while natural resources can support human needs, overconsumption threatens their availability. Sustainable development is important to ensure that:
Adopting sustainable development practices ensures a balance between economic growth and environmental protection.
