In which situation will the real pressure of population growth be understood as highest?

Answer and explanation

Correct answer: दर कम हो, पर आधार जनसंख्या बहुत बड़ी हो

Direct answer: A is correct. A growth rate is a percentage or proportion applied to a base population. Even a low rate can produce a large absolute increase when the base population is very large. For example, one percent of ten million is far more people than one percent of one hundred thousand. The additional people may require schools, hospitals, housing, water, food, transport and jobs, so the practical pressure can be high despite the apparently low rate. B suggests no growth and a small base, so pressure from increase is limited. C describes decline and outward migration, not the highest growth pressure. D indicates natural increase may be zero, although migration could still change the total; it does not by itself show the highest pressure. Memory cue: always read rate together with the base and calculate the actual addition.
