Question

Quizplus · Accepted Answer

The increase in average height of college students throughout the 20th century is attributed to the significant improvement in nutrition during this time. This is supported by research that shows that an individual's height is strongly influenced by their nutrient intake during childhood and adolescence. Therefore, as access to better nutrition became more widespread, individuals were able to reach their full genetic height potential, resulting in an overall increase in average height. The other choices (A, B, D) are not supported by evidence and are unlikely to explain the observed increase.
