Answer:
The correct answer is letter "C": whether the park is for everyone's pleasure.
Explanation:
During the passage, the author describes the problem of having "spandex" bicycle racers in Bidwell Park. In the beginning, the author exposes that what is bothering about them is the speed at what they ride their bicycles but, what if in the park the authorities would dedicate a special part for this kind of bikers to ride onto at the very same speed they use at the moment the author writes the passage. Will the author's point of view be the same? The answer is certainly unknown but there wouldn't be a reason for the complaint. So, mainly the issue is not the speed the riders ride at: it is the fact that they make feel others uncomfortable.
