If birth rate falls but death rate also falls, what should be checked before reaching a final conclusion?

Answer and explanation

Correct answer: Difference between both rates

Direct answer: A, check the difference between the birth rate and the death rate. Natural increase is not decided by looking at only one rate. First compare the original gap between births and deaths. Then compare the new gap after both rates have fallen. If the birth rate falls more than the death rate, natural increase may decrease; if the death rate falls more, the gap may increase; if both fall by the same amount, the gap may remain unchanged. A is correct because this comparison gives the relevant evidence. B, C, and D are not the quantities used in calculating natural increase. Area may matter for density, while rivers and soil may affect settlement, but none alone answers this question. Memory cue: compare the two rates, not just their direction.
