What is the safest exam strategy while studying processes of population change?

Answer and explanation

Correct answer: Understand births, deaths and migration separately and together

Correct answer: C. A reliable way to study population change is to understand each process separately and then combine them. Births increase population, deaths decrease it, in-migration adds people to a place, and out-migration removes people from it. After learning these individual effects, a student can analyse a complete situation by comparing all relevant components. Option C is correct because it prevents one-sided reasoning and helps solve questions involving more than one process. Option A is incomplete because births are only one component. Option B is incomplete because migration alone does not explain natural change. Option D is unsuitable because area is related more directly to density and distribution, not all population-change processes. Memory cue: first learn each arrow—births and in-migration point up, deaths and out-migration point down—then combine the arrows.
