These questions are based on the table below presenting data on percentage population covered by drinking water and sanitation facilities in selected Asian countries.
Country A is said to dominate B or A > B if A has higher percentage in total coverage for both drinking water and sanitation facilities, and, B is said to be dominated by A, or B < A. A country is said to be on the coverage frontier if no other country dominates it. Similarly, a country is not on the coverage frontier if it is dominated by at least one other country.Â
Which of the following statements are true?
A. India > Pakistan and India > Indonesia
B. India > China and India > Nepal
C. Sri Lanka > China
D. China > Nepal
India has lesser sanitation facilities than Pakistan. Hence it is false that India > Pakistan. So statement A is false.
India has greater sanitation facilities as well as drinking water coverage than China. Similar is the case between India and Nepal.
Hence, India > China and India > Nepal. So, statement B is true.
Sri Lanka has lesser drinking water coverage than China. Hence, statement C is false.
China has greater sanitation facilities as well as drinking water coverage than Nepal. Hence, China > Nepal and statement D is true.
So, the only two true statements are B and D.
