Ques 9 What is the main criterion used by the World Bank in classifying different countries? What are the limitations of this criterion, if any?
Ans: The main criterion used by the World Bank to classify different countries is through the per capita income or average income of a person in a country.
Limitations of this criterion:
This criteria does not inform about how the average income is distributed among the people in the individual countries. Two countries with the same per capita income might be very different with regard to income distribution. It is possible that one might have equitable distribution of income while the other might have great disparities between the rich and the poor.
Ques 10 Why is the issue of sustainability important for development?
Ans: The issue of sustainability is important for development because development must be in tandem with the future. If natural resources are not sustained, then development will stagnate after a point of time. Exploiting resources unethically will ultimately undo the development that a country may have achieved. This is because in the future, those resources will not be available for further progress.
