During middle childhood, which statement about growth is true?

• A. All children grow at approximately the same rate
• B. Most children become more thin
• C. Differences in the sizes of children become more marked
• D. Most children become more fat

Answer: (C)

In middle childhood, growth continues steadily, but children differ in how quickly they gain height and weight. Genetic factors set potential, while nutrition, health, and activity influence actual growth, so the pace varies from child to child. As these individual factors accumulate over several years, the gaps between kids’ sizes become more noticeable. That’s why the statement about differences in sizes becoming more marked is true—size differences widen even though everyone is growing. The other ideas assume uniform growth or universal trends toward thinning or fat, which isn’t accurate for most children in this stage.
