If death rate declines but birth rate remains high for some time what condition may occur?

Answer and explanation

Correct answer: Rapid natural increase

Direct answer: Option A. Natural increase is the difference between the birth rate and the death rate. When the death rate falls but the birth rate stays high, births are greater than deaths, so the population experiences rapid natural increase. This condition may continue until the birth rate also falls or another factor changes. Option A is correct because the gap between births and deaths becomes large and positive. Option B is wrong because negative growth occurs when deaths exceed births or when losses, such as out-migration, are greater than additions. Option C is wrong because equal births and deaths would be needed for zero natural increase, not high births with fewer deaths. Option D is wrong because birth and death rates do not determine whether migration ends. Memory cue: high births plus low deaths creates a large positive natural increase.
