Question 178

The television show Henry was not widely watched until it was scheduled for Tuesday evenings immediately after That's Life, the most popular show on television. During the year after the move, Henry was consistently one of the ten most-watched shows on television. Since Henry's recent move to Wednesday evenings, however, it has been watched by far fewer people. We must conclude that Henry was widely watched before the move to Wednesday evenings because it followed That's Life and not because people especially liked it.

Which one of the following, if true, most strengthens the argument?

Select an option, then click Submit answer.

  • ○

    Henry has been on the air for three years, but That's Life has been on the air for only two years.
  • ○

    The show that replaced Henry on Tuesdays has persistently had a low number of viewers in the Tuesday time slot.
  • ○

    The show that now follows That's Life on Tuesdays has double the number of viewers it had before being moved.
  • ○

    After its recent move to Wednesday, Henry was aired at the same time as the second most popular show on television.
  • ○

    That's Life was not widely watched during the first year it was aired.
Question 179

Joseph: My encyclopedia says that the mathematician Pierre de Fermat died in 1665 without leaving behind any written proof for a theorem that he claimed nonetheless to have proved. Probably this alleged theorem simply cannot be proved, since – as the article points out – no one else has been able to prove it. Therefore, it is likely that Fermat was either lying or else mistaken when he made his claim.

Laura: Your encyclopedia is out of date. Recently someone has in fact proved Fermat's theorem. And since the theorem is provable, your claim – that Fermat was lying or mistaken – clearly is wrong.

Joseph's statement that "this alleged theorem simply cannot be proved" plays which one of the following roles in his argument?

Select an option, then click Submit answer.

  • ○

    an assumption for which no support is offered
  • ○

    a subsidiary conclusion on which his argument's main conclusion is based
  • ○

    a potential objection that his argument anticipates and attempts to answer before it is raised
  • ○

    the principal claim that his argument is structured to refute
  • ○

    background information that neither supports nor undermines his argument's conclusion

  • ○

    It purports to establish its conclusion by making a claim that, if true, would actually contradict that conclusion.
  • ○

    It mistakenly assumes that the quality of a person's character can legitimately be taken to guarantee the accuracy of the claims that person has made.
  • ○

    It mistakes something that is necessary for its conclusion to follow for something that ensures that the conclusion follows.
  • ○

    It uses the term "provable" without defining it.
  • ○

    It fails to distinguish between a true claim that has mistakenly been believed to be false and a false claim that has mistakenly been believed to be true.
