If a country's population growth rate approaches zero, what is the most appropriate statement about doubling time?

Answer and explanation

Correct answer: Doubling time will become very long

Answer: B, doubling time becomes very long. For a positive growth rate, doubling time is inversely related to the rate: when growth becomes smaller, the population takes longer to double. As the rate approaches zero from above, the required time becomes extremely long. A states the opposite relationship. C is unjustified because doubling time depends on the actual growth rate; 35 years is not universal. D also reverses the relationship. If the rate becomes exactly zero and remains zero, doubling would not occur through growth. Memory cue: slower growth means a longer wait to double.
