Question 176

Twelve healthy volunteers with the Apo-A-IV-1 gene and twelve healthy volunteers who instead have the Apo-A-IV-2 gene each consumed a standard diet supplemented daily by a high-cholesterol food. A high level of cholesterol in the blood is associated with an increased risk of heart disease. After three weeks, the blood cholesterol levels of the subjects in the second group were unchanged, whereas the blood cholesterol levels of those with the Apo-A-IV-1 gene rose 20 percent.

Which one of the following is most strongly supported by the information above?

Select an option, then click Submit answer.

  • ○

    Approximately half the population carries a gene that lowers cholesterol levels.
  • ○

    Most of those at risk of heart disease may be able to reduce their risk by adopting a low-cholesterol diet.
  • ○

    The bodies of those who have the Apo-A-IV-2gene excrete cholesterol when blood cholesterol reaches a certain level.
  • ○

    The presence of the Apo-A-IV-1 gene seems to indicate that a person has a lower risk of heart disease.
  • ○

    The presence of the Apo-A-IV-2 gene may inhibit the elevation of blood cholesterol.
Question 177

High school students who feel that they are not succeeding in school often drop out before graduating and go to work.

This is encouraging evidence that the program instituted two years ago to improve the morale of high school students has begun to take effect to reduce dropouts.

Which one of the following, if true about the last year, most seriously weakens the argument?
