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.

Which countries are the countries on the coverage frontier?

  1. India and China
  2. Sri Lanka and Indonesia
  3. Philippines and Bangladesh
  4. Nepal and Pakistan

your answer is correct. But coverage frontier is defined using both water coverage and sanitation facility. Since Bangladesh has highest water coverage, no other country can dominate it and similarly the case for Philippines and sanitation facility.

what I thought is the country having highest water coverage and sanitation facilities will be called coverage frountier.

since no single country has highest coverage in both areas. I chose Bangladesh (highest drinking water coverage) and philippines (for sanitation facilities)

No, that logic is not correct. Try again- for coverage frontier, a country need not dominate all others- rather it should not be dominated.

So let's take it like this.

Bangladesh is not dominated by other countries for drinking water ( in urban 99 or rural 96 separately)

philippines is not dominated by any other countries for Sanitation facilities ( in urban 88 or rural 66 separately)
