Step-by-step explanation:
Based on the given information, Charles wants to study access to paved sidewalks, bike paths, and jogging trails to encourage fitness in his study community. To begin his research, he would most likely create a map of the community's built environment. The built environment refers to the human-made structures and spaces in an area, such as roads, buildings, and infrastructure.
Creating a map of the built environment would help Charles understand the existing infrastructure for pedestrians, cyclists, and joggers in his community. This information would be crucial for analyzing the accessibility and availability of sidewalks, bike paths, and jogging trails.
