In a study by Mika R. Moran, Daniel A. Rodriguez, and colleagues, residents of Mexico City, Mexico, and Bogotá, Colombia, 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 1,121 respondents from Bogotá, 71.9% indicated using city parks. Given that the percentage of respondents who reported having access to desired nonpark amenities was much lower in Mexico City than in Bogotá, the difference in park use can't be explained by Mexico City residents having more access to desired nonpark amenities near parks.
The text makes which point about the difference between the proportions of Mexico City residents and Bogotá residents using parks?
It is caused by something other than the parks' proximity to other desirable amenities.
A
It was greater than the researchers conducting the study expected.
B
It is the result of the difference in the number of respondents in each city.
C
It was calculated using sources that predate the survey.
D
