Answer
(a) The question is unbiased.
(b) This question has some bias. It could be reworded to ask, "To what extent do you support the town's ban on skateboarding in parts: Not at all, somewhat disagree, No strong feelings either way, somewhat agree, strongly agree."
Work Step by Step
(a) The question imposes an idea of "normal" on the person. A new parent or someone working a night shift will have a very different answer from someone working a white-collar job.
(b) It is biased because it primes the respondent to "agree" that the ban is "unfair." It uses loaded words and a question structure where the respondent is making a value judgment that is potentially at odds with the questioner.
