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 help drivers and cyclists avoid accidents, and they will make the downtown area more attractive to bike commuters.
Answer
A
Designated bike lanes have reduced traffic-related accidents by 43 percent in other cities.
B
A nearby city’s business district has bike lanes and a much higher population of commuters.
C
The cost of roadwork in the region has reduced the cost of similar projects by more than 12 percent.
D
Research has proven that bike commuters are healthier and happier than car commuters.
Explanation
The planner argues that bike lanes will improve safety by helping drivers and cyclists avoid accidents. Choice A gives direct evidence for that claim: designated bike lanes reduced traffic-related accidents by 43 percent in other cities. The other choices discuss commuter numbers, project costs, or commuters’ health and happiness, but do not directly show that bike lanes improve street safety.
