Text
In a study by Mika R. Moran, Daniel A. Rodriguez, and colleagues, residents of La Paz, Bolivia, and Fortaleza, Brazil, were surveyed about parks in their cities. Of the 528 respondents from La Paz, 67.5% indicated that they use the city's parks, and of the 938 respondents from Fortaleza, 35.7% indicated using city parks. Given that the percentage of La Paz respondents who reported living within a 10-minute walk of a park was much lower than that reported by Fortaleza respondents, greater proximity alone can't explain the difference in park use.
The text makes which point about the difference between the proportions of La Paz residents and Fortaleza residents using parks?
It was much larger than the researchers conducting the study expected.
A
It was calculated using sources that predate the survey.
B
It could be due to inaccuracies in the survey results.
C
It is caused by something other than the parks' proximity to city residents.
D
