Given that B: Births; \(X=\) Emigrants; \(D=\) Deaths; \(M=\) lmmigrants. The population of a country over a period of time will rise if ____________
A. \(B=D\) and \(X>M\) B. \(B-D=0\) and \(M>X\) C. \(D-B=O \text { and } M=X\) D. \(X>M \text { and } D>B\)
Correct Answer: B
Explanation
The population of a country can only rise if \(\mathrm{M}>\mathrm{X}\) or \(\mathrm{B}>\mathrm{D}\) or both. Since \(\mathrm{B}-\mathrm{D}=0\) and \(\mathrm{M}>X\), the population will still rise
