By this principle, we should pass the ordinance against skateboarding in the park, since that is a dangerous activity. This principle doesn't support the councillor's argument against the ban.

If anything, this principle suggests that the town should pass a ban on skateboarding in the park. It also gives us the criterion of being \"unnecessarily dangerous\", which doesn't clearly apply to the stimulus. This doesn't support the councillor's argument.

The councillor doesn’t reject the ban based on reasoning about children's skill levels and the role of parental involvement, which aren't mentioned. The councillor rejects the ban because it would put children in more danger.

This would also suggest that the ban should be put in place, since skateboarding in the park poses a danger to the children participating. But the councillor is arguing against the ban.

This supports the argument. Since the ban on skateboarding in the park would lead to the greater danger of skateboarding in the street, the ban shouldn’t be enacted.
