Why is the study of population growth useful for administration?

Correct answer: To plan services and facilities

Direct answer: A, to plan services and facilities. Administration needs information about the number of people, their age groups, location and rate of growth. This information helps authorities estimate how many schools, teachers, hospitals, health workers, houses, roads, water connections and sanitation facilities may be needed. The study of population does not give an exact guarantee about every future need, but it supports informed planning and fair distribution of resources. Option A is correct because public services are planned according to the size and changing needs of the population. Option B is wrong because population data cannot reduce mountain height. Option C is wrong because it has no connection with changing a river’s colour. Option D is wrong because administration studies population to serve people, not to remove soil. Memory cue: population information helps plan people-centred services.
