If the death rate declines but the birth rate remains high for a long time, what effect is possible?

Answer and explanation

Correct answer: The population may grow rapidly

Direct answer: A, the population may grow rapidly. Natural increase is the difference between the birth rate and the death rate. When deaths decline while births remain high, the gap between births and deaths becomes large and positive. This can produce rapid natural population growth, assuming that migration does not reverse the result. B is wrong because a lower death rate does not by itself cause an immediate decline; it generally means fewer people are being lost. C is wrong because high births combined with lower deaths produce positive, not negative, natural increase. D is wrong because the birth rate remains one of the main components of natural increase. The word “may” is important because migration and other conditions can also influence actual growth. Memory cue: high births plus fewer deaths create a wider positive gap.
