Read the scenario, then answer the question. a city planner thinks that reconfiguring the business district’s busy downtown streets to allow for bike lanes is important and is worth the large cost. the lanes will drivers and cyclists avoid accidents, and they will make the downtown area more attractive to bike commuters. which fact best supports the city planner’s opinion? designated bike lanes have reduced traffic-related accidents by 43 percent in other cities. a nearby city’s business district has bike lanes and a much higher population of commuters. the cost of roadwork in the region has reduced the cost of similar projects by more than 12 percent. research has proven that bike commuters are healthier and happier than car commuters.
