What can generally happen to population when death rate falls?

Answer and explanation

Correct answer: The population may increase

Answer: A, the population may increase. Population change is affected mainly by births, deaths, and migration. The death rate tells us how many people die in a population during a given period. When the death rate falls, more people survive. If the birth rate and migration remain broadly unchanged, the number of births may become greater than the number of deaths, so the total population can rise. Option A is correct because it states a likely general effect without claiming that increase is guaranteed in every situation. Option B is incorrect because fewer deaths can change the total population. Option C is incorrect because a lower death rate does not normally make the population decrease. Option D is incorrect because, other things being equal, fewer deaths usually support a higher, not lower, rate of population growth. Memory cue: more births and fewer deaths usually mean population increase.
