Final answer:
It is reasonable to expect children to walk less than a mile to school because it promotes health through physical activity, saves on transportation costs, and reduces traffic congestion, justifying the answer 'D) All of the above'.
Step-by-step explanation:
Exploring why it is reasonable to expect children to walk less than a mile to school involves considering several key benefits, such as promoting physical activity and health, saving on transportation costs, and reducing traffic congestion. This multifaceted approach aligns with broader health and community initiatives, like the Let's Move! campaign, which stresses the importance of physical activity for children. By walking to school, children get regular exercise, which is crucial for maintaining a healthy weight and preventing childhood obesity. This daily active routine can also help foster a healthy heart and brain development, and instill lifelong healthy habits. Moreover, walking less than a mile to school can save money for families and reduce the number of vehicles on the road, leading to less traffic and potential environmental benefits.
Therefore, choosing the answer 'D) All of the above' is justified as it incorporates all the mentioned advantages. When considering the options, it's important to think about the comprehensive impact walking can have—not only on the individual health of the children but also on financial implications for families, and the broader effects on traffic and environmental health.
