Final answer:
The three levels of walkability scores are Low, Medium, and High, which evaluate how conducive an area is to walking based on various factors.
Step-by-step explanation:
The three levels of walkability scores are: A) Low, Medium, High. Walkability scores are assigned to locations based on how friendly an area is to walking. Factors that contribute to a location's walkability include the presence of footpaths, pedestrian rights-of-way, traffic and road conditions, land use patterns, building accessibility, and safety. These scores help individuals understand how easily they can accomplish errands on foot in a given area. A high walkability score indicates that most errands can be accomplished without the need for a vehicle, while a low score suggests that a car may be necessary for most outings.
