Time—35 minutes

25 Questions

Directions: The questions in this section are based on the reasoning contained in brief statements or passages. For some questions, more than one of the choices could conceivably answer the question. However, you are to choose the best answer, that is the response that most accurately and completely answers the question. You should pot make assumptions that are by commonsense standards implausible, superfluous, or incompatible with the passage After you have chosen the best answer, blacken the corresponding space on you answer sheet.

1. Press release A comprehensive review evaluating the medical studies done up to the present time has found no reason to think that drinking coffee in normal amounts harms the coffee-drinker s heart So coffee drinkers can relax and enjoy their beverage—it is safe to drink coffee

  Which one of the following points to a weakness in the reasoning in the press release s argument?

(A) The review was only an evaluation of studies and did not itself undertake to   study patients.
(B) The health of the heart is not identical with the general health of the body
(C) Coffee drinkers might choose to eat along with their coffee foods contaming   substances that harm the heart
(D) Other beverages besides coffee might contain stimulants that have some   effect on the heart
(E) Drinking unusually large amounts of coffee could be caused by stress that   itself directly harms the heart

2. All people prefer colors that they can distinguish easily to colors that they have difficulty distinguishing. Infants can easily distinguish bright colors but, unlike adults, have difficulty distinguishing subtle shades. A brightly colored toy for infants sells better than the same toy in subtle shades at the same price

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

(A) Infants prefer bright primary colors to bright secondary colors
(B) Color is the most important factor in determining which toys an infant will   prefer to play with
(C) Individual infants do now have strong preferences for one particular bright   color over other bright colors
(D) The sales of toys ofr infants reflect the preferences of infants in at least one   respect
(E) Toy makers study infants to determine what colors the infants can   distinguish easily

3. A group of unusual meteorites was found in Shergotty. India. Their structure indicates that they originated on one of the geologically active planets. Mercury, Venus, or Mars Because of Mercury s proximity to the Sun any material dislodged from that planet s surface would have been captured by the Sun, rather than falling to Earth as meteorites, Nor could Venus be the source of the meteorites, because its gravity would have prevented dislodged material from escaping into space The meteorites, therefore, probably fell to Earth after being dislodged from Mars, perhaps as the result of a collision with a large object

  The argument derives its conclusion by

(A) offering a counterexample to a theory
(B) eliminating competing alternative explanations
(C) contrasting present circumstances with past circumstances
(D) questioning an assumption
(E) abstracting a general principle from specific data

4. Because quitting smoking is very stressful and leads to weight gain, it is difficult to do. The key to quitting however, may be as simple as replacing an unhealthy activity with a healthy one In one study half of htose attempting to quit were assigned to a smoking-cessation program alone, and the other half were assigned to the same program plus fifteen weeks of aerobic exercise the one-month mark none in the first group had quit but 40 percent of those in the second group had not smoked

  Each of the following, if true, provides some support for the argument EXCEPT:

(A) Regular exercise prevents weight gain
(B) Each group in the study included four hundred randomly selected   participants
(C) Nonsmokers accustomed to regular exercise do not gain weight when they   stop exercising
(D) Aerobic exercise can stimulate the brain s production of endorphins. which   reduce tension
(E) Of those in the second group in the study 38 percent had not smoked at the   one-year mark.

5. Altogethe, the students in Ms. Tarnowski s Milton Elementary School class collected more aluminum cans than did the students in any of the school s other classes Therefore, the Milton student who collected the most aluminum cans was in Ms Tarnowski s class

  Which one of the following arguments contains flawed reasoning that is most paralled to that in the argument above?

(A) Altogether, more trees were planted by the students in Mr Kelly s class than   were planted by those in Mr Liang s class and Mr Jackson s class   combined Therefore. Mr Kelly s students planted more trees than Mr   Jackson s students planted
(B) More than half of Milton Elementary School s students play in the band and   more than half of the school s students sing in the choir Therefore, every   student at Milton Elementary School either plays in the band or sings in   the choir
(C) Mr Rowe s Milton Elementary School class raised more money by selling   candy bars than Ms Hunt s class raised by holding a raffle. Therefore, the   number of candy bars sold by Mr Rowe s class was greater than the   number of raffle tickets sold by Ms. Hunt s class
(D) The total number of tickets to the school fair sold by the students in Ms.   Ramirez s Milton Elementary School class was greater than the number   sold by Milton students from any other class. Therefore, the Milton student   who sold the most tickets to the school fair was a student in Ms Rairez s   class
(E) Ms. Ventura s Milton Elementary School class assembled more birdhouses   than did any of the school s other classes. Since Ms Ventura s class had   fewer students than any other Milton class, her students assembled more   birdhouse on average than did the students in any other Milton class

6. Several excellent candidates have been proposed for the presidency of United Wire and each candidate would bring to the job different and experience If the others are compared with Jones however it will be apparent that none of them has her unique set of qualifications Jones therefore is best qualified to be the new president of United Wire

14. Steven The allowable blood alcohol level for drivers should be cut in half With this reduced limit, social drinkers will be deterred from drinking and driving, resulting in significantly increased highway safety

Miguel: No lowering the current allowable blood alcohol level would have little effect on highway statey because it would not address the most important aspect of the drunken driving problem which is the danger to the public posed by heavy drinkers who often drive with a blood alcohol level of twice the current legal limit.

Steven and Miguel s statements provide the most support for that they would disagree about the truth of which one of the following statements?

Questions 15-16

  The authors of a recent article examined warnings of an impending wave of extinctions of animal species within the next 100 years. These authors say that no evidence exists to support the idea that the rate of extinction of animal species is now accelerating. They are wrong however Consider only the data on fishes 40 species and subspecies of North American fishes have vanished in the twentieth century, 13 between 1900 and 1950, and 27 since 1950

15. Which one of the following is the main point of the argument?

(A) There is evidence that the rate of extinction of animal species is   accelerating
(B) The future rate of extinction of animal species cannot be determined from   available evidence
(C) The rate of extinction of North American fishes is parallel to the rate of   extinction of all animal species taken together
(D) Forty species and subspecies of North American fishes have vanished in   the twentieth century
(E) A substantial number of fish species are in danger of imminent extinction

16. The answer to which one of the following questions would contribute most to an evaluation of the argument?

(A) Were the fish species and subspecies that became extinct   unrepresenatative of animal species in general with regard to their pattern   of extinction?
(B) How numerous were the populations in 1950 of the species and subspecies   of North American fishes that have become extinct since 1950?
(C) Did any of the species or subspecies of North American fishes that became   extinct in the twentieth century originate in regions outside of North   America?
(D) What proportion of North American fish species and subspecies whose   populations were endangered in 1950 are now thriving?

17. After the Second World War, the charter of the newly formed United Nations established an eleven-member Security Council and charged it with taking collective action in response to threats to world peace. The charter further provided that the five nations that were then the major powers would permanently have sole authority to cast vetoes. The reason given for this arrangement was that the burden of maintaining world peace would rest on the world s major powes and should be required to assume the burden of enforcing a decision it found repugnant

  The reasoning given for the structure of the Security Council assumes that

(A) it does not make sense to provide for democracy among nations when   nations themselves are not all democracies
(B) no nation that was not among the major powers at the end of the Second   World War would become a major power
(C) nations would not eventually gravitate into large geographical bloes, each   containing minor powers as well as at least one major power

18. Environmental scientist: It is true that over the past ten years, there has been a sixfold increase in government funding for the preservation of wetlands while the total area of wetlands needing such preservation has increased only twofold (although this area was already large ten years ago) Even when inflation is taken into account, the amount of funding now is at least three times what it was ten years ago. Nevertheless the current amount of government funding for the preservation of wetlands is inadequate and should be augmented

  Which one of the following, if true most helps to reconcile the environmental scientist s conclusion with the evidence cited above?

(A) The governmental agency responsible for administering wetland-preservation   funds has been consistently mismanaged and run inefficiently over the past   ten years
(B) Over the past ten years, the salaries of scientists employed by the   government to work on the preservation of wetlands have increased at a   rate higher than the inflation rate
(C) Research over the past ten years has enabled scientists today to identify   wetlands in need of preservation well before the areas are at serious risk of   destruction
(D) More people today scientists and nonscientists alike, are working to   preserve all natural resources including wetlands
(E) Unlike today funding for the preservation of wetlands was almost   nonexistent ten years ago.

19. In Australia the population that is of driving age has grown large over the last five years, but the annual number of traffic fatalities has declined. This leads to the conclusion that, overall, the driving-age population of Australi consists of more skillful drivers now than five years ago.

  Each of the statements below, if true, weakens the argument EXCEPT:

(A) Three years ago, a mandatory seat-belt law went into effect throughout   Australia.
(B) Five years ago. Australia began a major road repair project
(C) Because of increases in the price of fuel Australians on average drive less   each year than in the preceding year.

(E) What appear to be differences in values between distinct cultures are   nothing more than differences in beliefs about how to live in accordance   with shared values.

21. Newspaper editor. Law enforcenment experts, as well as most citizens, have finally come to recognize that legal prohibitions against gambling all share a common flaw no matter how diligent the effort, the laws are impossible to enforce.

  Which one of the following if assumed. allows the argument s conclusion to be properly drawn?

(A) No effective law is unenforceable
(B) All enforceable laws are effective
(C) No legal prohibitions against gambling are enforceable

22. Copernicus s astronomical system is superior to Ptolemy s and was so at the time it was proposed, even though at that time all observational evidence was equally consistent with both theories. Ptolemy believed that the stars revolved around the earth at great speeds. This struck Copernicus as unlikely, he correctly thought that a simpler theory is that the earth rotates on its axis.

  The argument most closely conforms to which one of the following principles?

(A) Simplicity should be the sole deciding factor in choosing among competing   scientific theories
(B) If one theory is likely to be true, and another competing theory is likely to be   false, then the one likely to be true is the superior of the two.
(C) If all observational evidence is consistent with two competing theories, the   one that is more intuitively true is the more practical theory to adopt.
(D) Other things being equal the more complex of two competing theories is the   inferior theory
(E) Other things being equal, the simpler of two competing theories is the more   scientifically important theory.

23. Easayist The existence of a moral order in the universe—i.e..an order in which bad is always eventually punished and good rewarded—depends upon human souls being immortal. In some cultures this moral order is regarded as the result of a karma that controls how one is reincarnated, in others it results from the actions of a supreme being who metes out justice to people after their death. But however a moral order is represented if human souls are immortal then if follows that the bad will be punished

(B) The argument takes mere beliefs to be established facts
(C) From the claim that the immortality of human souls implies that there is a   moral order in the universe the argument concludes that there being a   moral order in the universe implies that human souls are immortal
(D) The argument treats two fundamentally different conceptions of a moral   order as essentially the same
(E) The argument s conclusion is presupposed in the definition it gives of a   moral order.

(E) Knowing a proposition to be true requires proving it true by observation

25. The publisher of a best-selling self-help book had, in some promotional material, claimed that it showed readers how to become exceptionally successful. Of course everyone knows that no book can deliver to the many what by definition, must remain limited to the few exceptional success. Thus although it is clear that the publisher knowingly made a false claim. doing so should not be considered unethical in this case

  Which one of the following principles if valid most strongly supports the reasoning above?

(A) Knowingly making a false claim is unethical only if it is reasonable for   people to accept the claim as true
(B) Knowingly making a false claim is unethical if those making it derive a gain   at the expense of those acting as if the claim were true.
(C) Knowingly making a false claim is unethical in only those cases in which   those who accept the claim as true suffer a hardship greater than the gain   they were anticipating
(D) Knowingly making a false claim is unethical only if there is a possibility that   someone will act as if the claim might be true
(E) Knowingly making a false claim is unethical in at least those cases in which   for someone else to discover that the claim is false that person must have   acted as if the claim were true
