A city's total population grows by 28 percent but the number of children grows by only 2 percent. What is the strongest conclusion?

Answer and explanation

Correct answer: Much of the growth came from age groups other than children

The total population and the child population have grown at very different rates. Total population increased by 28 percent, whereas the number of children increased by only 2 percent. Thus, children explain only a small part of the overall increase, while other age groups must account for much of it.

The strongest conclusion is that much of the growth came from age groups other than children, so option A follows. Migration of working-age people is one possible reason, although the figures alone do not prove a particular cause. A 28 percent total increase does not mean that births or children also increased by 28 percent. Therefore, options B and C are unsupported, and D is false.
