In a study by Mika R. Moran, Daniel A. Rodriguez, and colleagues, residents of Mexico City, Mexico, and La Paz, Bolivia, were surveyed about parks in their cities. Of the 562 respondents from Mexico City, 77.6% indicated that they use the city's parks, and of the 528 respondents from La Paz, 67.5% indicated using city parks. Given that the percentage of Mexico City respondents who reported living within a 10-minute walk of a park was much lower than that reported by La Paz respondents, greater proximity alone can't explain the difference in park use.
The text makes which point about the difference between the proportions of Mexico City residents and La Paz residents using parks?
It could be due to inaccuracies in the survey results.
A
It was calculated using sources that predate the survey.
B
It was much larger than the researchers conducting the study expected.
C
It is caused by something other than the parks' proximity to city residents.
D
