Questions: Which one of the following is an example of physical maturation? Gaining weight from age two to age three Losing weight due to exercise Losing weight during a brief illness Learning which foods produce the most weight

The answer is the first one: gaining weight from age two to age three.

Explanation for each option:

1. Gaining weight from age two to age three: This is an example of physical maturation. Physical maturation refers to the natural growth and development processes that occur as a child ages, including increases in height and weight.

2. Losing weight due to exercise: This is not an example of physical maturation. Weight loss due to exercise is a result of lifestyle choices and physical activity, not a natural developmental process.

3. Losing weight during a brief illness: This is also not an example of physical maturation. Weight loss during illness is typically temporary and related to health conditions rather than natural growth and development.

4. Learning which foods produce the most weight: This is not an example of physical maturation. It involves cognitive learning and decision-making about diet, not a natural physical growth process.

In summary, physical maturation involves natural growth and development, such as gaining weight as a child grows, making the first option the correct example.
