Information about population growth helps government in what?

Correct answer: Planning future services

The direct answer is A: planning future services. Population-growth information tells the government how the number and needs of people may change. Using such information, planners can estimate future requirements for schools, hospitals, housing, drinking water, sanitation, roads, public transport, food distribution, and employment programmes. The information does not give a perfect prediction, but it supports evidence-based planning and helps resources reach the people who need them. Option A is correct because services must be planned according to present and expected population. Option B is wrong because population data cannot change the colour of the sea. Option C is wrong because removing mountains is a geological or engineering matter, not the normal purpose of population statistics. Option D is wrong because clouds and sound have no logical connection with population planning. Memory cue: population data helps answer “how many people will need which services, and where?”
