A recent study observed that city residents who live within one mile of a public park report significantly higher levels of subjective well-being than those living further away. The city planning committee concluded that increasing the number of small neighborhood parks will improve the overall mental health of the city's population.
Which of the following, if true, most seriously weakens the planning committee's conclusion?
- Maintaining a large network of many small neighborhood parks costs the city substantially more per year than operating a single large central park
- No neighborhood park anywhere has ever once been shown to produce a measurable improvement in any single resident's mental health
- Some residents who live next to parks have lodged repeated complaints about elevated noise levels during peak weekend hours
- A prior study in a different city found that park proximity was just one of several distinct factors that shaped residents' overall happiness
- People who already prioritize an active lifestyle and mental wellness tend to seek out and move into housing near existing green spaces
