Question 238

Town councillor: The only reason for the town to have ordinances restricting where skateboarding can be done would be to protect children from danger. Skateboarding in the town's River Park is undoubtedly dangerous, but we should not pass an ordinance prohibiting it. If children cannot skateboard in the park, they will most certainly skateboard in the streets. And skateboarding in the streets is more dangerous than skateboarding in the park.

Which one of the following principles, if established, would provide the strongest support for the town councillor's argument?

Select an option, then click Submit answer.

  • ○

    Ordinances that restrict the recreational activities of a town's inhabitants should not be passed unless those activities pose a danger to participants.
  • ○

    Since the town could be legally liable for accidents that occur on public property, town ordinances should restrict any unnecessarily dangerous activities in publicly owned areas.
  • ○

    Since safety in a recreational activity depends on the level of skill of the participant in that activity, the regulation of children's recreational activities should be left to the discretion of the children's parents.
  • ○

    If recreational activities constitute a danger to the participants in those activities, then the town council should enact ordinances prohibiting those activities.
  • ○

    Ordinances that seek to eliminate dangers should not be enacted if their enactment would lead to dangers that are greater than those they seek to eliminate.
Question 239

Journalist: One reason many people believe in extrasensory perception (ESP) is that they have heard of controlled experiments in which ESP is purportedly demonstrated. However, ESP is a myth and the public is deluded by these experiments, for a prominent researcher has admitted to falsifying data on psychic phenomena in order to obtain additional grants.

The reasoning in the journalist's argument is flawed because this argument

  • ○

    uses an irrelevant personal attack on the integrity of someone
  • ○

    infers that something must be a myth from the fact that the general public believes it
  • ○

    presupposes that, in general, only evidence from experiments can support beliefs
  • ○

    implies that all scientists who depend on grants to support their research are unreliable
  • ○

    overgeneralizes from the example of one deceptive researcher
Question 240

One way kidney stones can form is when urine produced in the kidneys is overly concentrated with calcium or oxalate. Reducing dietary calcium has been thought, therefore, to decrease the likelihood that calcium will concentrate and form additional stones. Oddly enough, for many people the chances of recurrence are decreased by increasing calcium intake.

Which one of the following, if true, most helps to resolve the apparent discrepancy described above?

Select an option, then click Submit answer.

  • ○

    Laboratory studies on animals with kidney stones reveal that they rarely get additional stones once calcium supplements are added to the diet.
  • ○

    Increasing dietary oxalate while reducing dietary calcium does not reduce the chances of kidney stone recurrence.
  • ○

    Kidney stone development is sometimes the result of an inherited disorder that can result in excessive production of calcium and oxalate.
  • ○

    Increasing calcium intake increases the amount of calcium eliminated through the intestines, which decreases the amount to be filtered by the kidneys.
  • ○

    Some kidney stones are composed of uric acid rather than a combination of calcium and oxalate.
