Question

1. melvins community added bicycle lanes to its roads, and now many people are biking to school or work rather than driving cars. which aspect of environmental health did this community action most likely improve?

air quality
fitness
public safety
water quality

Explanation:

When people bike instead of drive cars, there are fewer vehicle emissions. Vehicle emissions are a major source of air pollution. Reducing these emissions directly improves air quality. Fitness is more related to the individual's physical activity (like the act of biking itself for personal fitness), but the question is about the environmental health aspect. Public safety could be marginally affected (e.g., bike lanes making biking safer), but it's not the main environmental health aspect here. Water quality is not directly impacted by this change from driving to biking.

Answer:

air quality
