Question 220

It is proposed to allow the sale, without prescription, of a medication that physicians currently prescribe to treat the common ear inflammation called "swimmer's ear." The principal objection is that most people lack the expertise for proper self-diagnosis and might not seek medical help for more serious conditions in the mistaken belief that they have swimmer's ear. Yet in a recent study, of 1,000 people who suspected that they had swimmer's ear, 84 percent had made a correct diagnosis- – a slightly better accuracy rate than physicians have in diagnosing swimmer's ear. Thus, clearly, most people can diagnose swimmer's ear in themselves without ever having to consult a physician.

Which one of the following, if true, most undermines the conclusion?

Select an option, then click Submit answer.

  • ○

    Cases in which swimmer's ear progresses to more serious infections are very rare.
  • ○

    Most of those who suspected incorrectly that they had swimmer's ear also believed that they had other ailments that in fact they did not have.
  • ○

    Most of the people who diagnosed themselves correctly had been treated by a physician for a prior occurrence of swimmer's ear.
  • ○

    Physicians who specialize in ear diseases are generally able to provide more accurate diagnoses than those provided by general practitioners.
  • ○

    For many people who develop swimmer's ear, the condition disappears without medical or pharmaceutical intervention.
Question 221

Social critic: The whole debate over the legal right of rock singers to utter violent lyrics misses the point. Legally, there is very little that may not be said. But not everything that may legally be said, ought to be said. Granted, violence predates the rise in popularity of such music. Yet words also have the power to change the way we see and the way we act.

Which one of the following is most strongly supported by the passage?

Select an option, then click Submit answer.

  • ○

    If rock music that contains violent lyrics is morally wrong, then it should be illegal.
  • ○

    The law should be changed so that the government is mandated to censor rock music that contains violent lyrics.
  • ○

    Violent rock song lyrics do not incite violence; they merely reflect the violence in society.
  • ○

    If rock musicians voluntarily censor their violent lyrics; this may help to reduce violence in society.
  • ○

    Stopping the production of rock music that contains violent lyrics would eliminate much of the violence within society.
Question 222

For all species of higher animals, reproduction requires the production of eggs but not necessarily the production of sperm. There are some species whose members are all female; the eggs produced by a rare female-only species of salamander hatch without fertilization. This has the drawback that all offspring have genetic codes nearly identical to that of the single parent, making the species less adaptive than species containing both male and female members.

If the statements above are true, each of the following could be true EXCEPT:

  • ○

    There are some species of salamanders that have both male and female members.
  • ○

    There are some species of higher animals none of whose members produce eggs.
  • ○

    There is a significant number of female-onlyspecies of higher animals.
  • ○

    Some species of higher animals containing both female and male members are not very adaptive.
  • ○

    Some offspring of species of higher animals containing both female and male members have genetic codes more similar to one parent than to the other parent.
