Problem 3 - Entrance Test

To improve public health, the city should invest more in building bike lanes. Studies show that cities with extensive bike lane networks have lower rates of obesity and heart disease among their residents. Which of the following is an assumption on which the argument relies?

Correct: B

The argument proposes building bike lanes to improve public health by reducing obesity and heart disease. For this plan to work, it is implicitly assumed that residents will use these bike lanes, leading to increased physical activity. If residents don't use the bike lanes, the desired health outcomes won't materialize, regardless of the correlation found in other cities. Option A compares cost-effectiveness, which is not directly assumed for the plan to work. Option C exaggerates the scope of health concerns. Option D is a factual premise about the current state, not an assumption about the intervention's success.
