8  Drug manufacturer: Although our company requires that patients who use our new drug also 
    purchase from us nonreusable kits for weekly blood testing, the expense of those kits is an
    entirely necessary one: weekly blood testing must be done to monitor the drug's potential
    side effects, which can be very dangerous.
    Which of the following, if true, most seriously weakens the manufacturer's argument?
(A) The expense of purchasing the blood-test kits has not prevented any patients from obtaining
      them or the drug.
(B) Medical laboratories can perform the blood testing at a lower cost to patients or their insurers
      than the price the manufacturer charges for the kits.
(C) A one-year supply of the drug and the weekly blood-test kits can cost patients or their
      insurers over $10,000.
(D) Most government and other health insurance programs will not reimburse patients for the
      full cost of both the drug and the blood-test kits.
(E) Patients who suffer one or more of the dangerous side effects of the drug can incur heavy

9 Virginia and her brother William disagree over when their father was born: Virginia claims it was
   in 1935 and William claims it was in 1933. The hospital where their father was born has no     
   records for 1933 but has complete records for 1935— records that do not include a birth record 
   for their father. Therefore, he must have been born in 1933. The argument depends on which of 
   the following assumptions?
(A) Either Virginia's claim or William's claim is correct.
(B) The records of the hospital where their father was born date back to 1933.
(C) Virginia and William know the day and the month of their father's birth.
(D) There are urgent practical reasons why Virginia and William must know the date of their
      father's birth.
(E) None of their other relatives knows the year in which Virginia and William's father was born.

10. RESULTS OF TWO SURVEYS OF OPINIONS REGARDINGTHE EFFECTS OF SCIENCE OF HUMAN   
     SOCIETY

     Mostly beneficial 25% 81%
     Equally harmful 37% 9%
     and beneficial
     Mostly harmful 20% 7%
     No opinion 18% 3%
     Which of the following, if true, contributes most to explaining the shift in opinions about the   
     effects of science on human society?
(A) The surveys questioned people who regularly watch prime-time television, and an innovative
      weekly prime-time television series called "Wonders of Science"had been steadily winning       
      viewers since its widely seen premiere in January 1992.
(B) The surveys questioned college-educated adults, and a report called "The State of the Nation's
      Schools," published in June 1992, noted an increase in students’ interest in science courses   
      since 1982.
(C) The surveys were conducted in a suburban shopping area near a company that ceased
      operation in April 1992 as a result of lawsuits arising from unexpected toxic effects of the
      company's products.
(D) Both survey forms were mailed to equally large samples of the population; after returning the 
      1991 survey forms, respondents were sent discount coupons for food products, and after
      returning the 1992 survey forms, respondents were sent a pamphlet on recycling.
(E) The surveys questioned first-year college students across the country, and the people who did 
      the questioning were all research scientists.

23 The town of San Leonardo has recently enacted a law banning smoking in all restaurants within 
     town limits. Since many smokers who normally dine in San Leonardo's restaurants will not want
     to refrain from smoking during their meals, San Leonardo's restaurants will undoubtedly lose 
     many patrons and considerable income. Which of the following, if true, most helps to strengthen
     the argument above?
(A) Most residents of San Leonardo who eat in restaurants are not smokers.
(B) Most smokers who dine in the company of nonsmokers are willing to refrain from smoking
     during their meals.
(C) If the law banning smoking in restaurants had not been enacted, it is likely that a more
      stringent law banning smoking in all public places in San Leonardo would have been
      enacted instead.
(D) Prior to the enactment of the law banning smoking in San Leonardo's restaurant, the
      town had a law that required most restaurants to have nonsmoking sections.
(E) None of the other communities adjacent to San Leonardo, which have restaurants comparable
      to those of San Leonardo, has enacted and enforces any antismoking legislation.

24. Children whose biological parents both have Tic Syndrome Z (TSZ), which is characterized by 
      the involuntary contraction of certain muscles, are about four times more likely to develop such
      contractions than are children whose biological parents do not have TSZ, It is likely, therefore,   
      that predisposition to TSZ is an inherited trait.
      Which of the following, if true, would most strengthen the conclusion above?
(A) Children whose parents have TSZ are more likely to develop TSZ if they are under unusual
      stress at school or at home than if they are not under such stress.
(B) Children whose biological parents do not have TSZ are more likely to develop TSZ if they are
      raised by adoptive parents with TSZ than if they are raised by their biological parents.
(C) Children whose biological parents have TSZ are as likely to develop TSZ if they are raised by
      adoptive parents who do not have TSZ as if they are raised by their biological parents.
(D) Children whose biological parents have TSZ and who develop TSZ usually avoid developing a
      severe form of the syndrome if they seek treatment for TSZ shortly after developing the first
      signs of it.
(E) Children with TSZ whose biological parents do not have TSZ are less likely to have the   
      syndrome diagnosed when symptoms first appear than are children with TSZ whose biological
      parents have TSZ.

25. Playing eighteenth-century music on the instruments of that period provides valuable 
      information about how the music originally sounded. Eighteenth-century instruments
      cannot be played without being restored, however, and restoring such an instrument destroys 
      all of the information that researchers could obtain from it about eighteenthcentury
      instrument-making techniques. If the statements above are true, which of the following
      must be true on the basis of them?
(A) Eighteenth-century instruments cannot be used to provide information about the original
      techniques used in playing such instruments if they have been restored.
(B) Eighteenth-century instruments that have been restored can provide information only about how
      eighteenth-century music originally sounded
(C) Eighteenth-century instruments are the only source of information about the instrument-making
      techniques of that period.
(D) An eighteenth-century instrument that has not been restored can provide more information than
      can one that has been restored.
(E) An eighteenth-century instrument cannot serve as a source of new information about eighteenth-
     century instrument-making techniques once it can be played
