  SECTION II

  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 not 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 your answer sheet.

  1. A law that is not consistently enforced does not serve its purpose. Law without enforcement is not law, it is merely stature-a promise of law. To institute real law is not merely to declare that such and such behavior is forbidden, it is also to punish those who violate that edict. Furthermore, those who enforce law must punish without favor for their friends or malice for their enemies. To punish only those own dislike while forgiving others is not to enforce law but to engage in the arbitrary and unjust exercise of power.

  The main point of the passage is that instituting real law consists in

  (A) the exercise of power

  (B) authorizing the enforcement of punishments

  (C) the unbiased punishment of prohibited behavior

  (D) understanding the purpose of law

  (E) clearly defining unacceptable behavior

  2. Physiological research has uncovered disturbing evidence linking a number of structural disorder disorders to logging. Among the ailments seemingly connected with this now-popular sport are spinal disk displacements, stress fractures of the feet and ankles, knee and hip joint deterioration, and tendonitis. Furthermore, these injuries do not occur exclusively among beginning runners-veteran joggers suffer an equal percentage of injuries. What the accumulating data suggest is that the human anatomy is not able to withstand the stresses of jogging.

  Which one of the following is an assumption of the argument?

  (A) The link between jogging and certain structural disorders appears to be a causal one.

  (B) Jogging causes more serious disorders than other sports.

  (C) The jogger's level of experience is a factor determining the likelihood of a jogging injury.

  (D) Some sports are safer for the human body than jogging.

  (E) The human species is not very durable.

  3. All students at Pitcombe College were asked to label themselves conservative, liberal, or middle-of-the-road politically. Of the students, 25 percent labeled themselves conservative,24 percent labeled themselves liberal, and 51 percent labeled themselves middle-of-the-road. When asked about a particular set of issues, however, 77 percent of the students endorsed what is generally regarded as a liberal position.

  If all of the statements above are true, which one of the following must also be true?

  (A) All students who labeled themselves liberal endorsed what is generally regarded as a liberal position on that set of issues.

  (B) More students who labeled themselves middle-of-the road than students who labeled themselves liberal opposed what is generally regarded as a liberal position on that set of issues.

  (C) The majority of students who labeled themselves middle-of-the-road opposed what is generally regarded as a liberal position on that set of issues.

  (D) Some students who labeled themselves conservative endorsed what is generally regarded as a liberal position on that set of issues.

  (E) Some students who labeled themselves liberal endorsed what is generally regarded as a conservative position on that set of issues.

  4. Lenore: It is naive to think that historical explanations can be objective. In evaluating evidence, historians are always influenced by their national, political, and class loyalties.

  Victor: Still, the very fact that cases of biased thinking have been detected and sources of bias identified shows that there are people who can maintain objectivity.

  Victor's response does not succeed as a rebuttal of Lenore's argument because his response

  (A) displays the same kind of biased thinking as that against which Lenore's argument it directed

  (B) does not address the special case of historians who purposely distort evidence in order to promote their own political objectives

  (C) fails to provide examples of cases in which biased thinking has been detected and the source of that bias identified

  (D) does not consider sources of bias in historical explanation other than those that are due to national, political, and class loyalties

  (E) overlooks the possibility that those who detect and identify bias are themselves biased in some way

  5. The museum's night security guard-maintains that the thieves who stole the portrait did not enter the museum at any point at or above ground level. Therefore, the thieves must have gained access to the museum from below ground level.

  The flawed pattern of reasoning in the argument above is most similar to that in which one of the following?

  (A) The rules stipulate the participants in the contest be judged on both form and accuracy. The eventual winner was judged highest in neither category , so there must be a third criterion that judges were free to invoke.

  (B) The store's competitors claim that the store in selling off the shirts at those prices, neither made any profit nor broke even. Consequently, the store's customers must have been able to buy shirts there at less than the store's cost.

  (C) If the census is to be believed, the percentage of men who are married is higher than the percentage of women who are married. Thus, the census must show a higher number of men than of women overall.

  (D) The product label establishes that this insecticide is safe for both humans and pet. Therefore, the insecticide must also be safe for such wild mammals as deer and rabbits.

  (E) As had generally been expected, not all questionnaires were sent in by the official deadline. It follows that plans must have been made for the processing of questionnaires received late.

  Questions 6-7

  High-technology medicine is driving up the nation's health care costs. Recent advances in cataract surgery illustrate why this is occurring. Cataracts are a major cause of blindness, especially in elderly people. Ten years ago, cataract surgery was painful and not always effective.

  12. By dating fossils of pollen and beetles, which returned after an Ice Age glacier left an area, it is possible to establish an approximate date when a warmer climate developed. In one glacial area, it appears from the insect record that a warm climate developed immediately after the melting of the glacier. From the pollen record, however, it appears that the warm climate did not develop until long after the glacier disappeared.

  Each one of the following, if true, helps to explain the apparent discrepancy EXCEPT:

  (A) Cold-weather beetle fossils can be mistaken for those of beetles that live in warm climates.

  (B) Warm-weather plants cannot establish themselves as quickly as can beetles in a new environment.

  (C) Beetles can survive in a relatively barren postglacial area by scavenging.

  (D) Since planes spread unevenly in a new climate, researchers can mistake gaps in the pollen record as evidence of no new overall growth.

  (E) Beetles are among the oldest insect species and are much older then many warm-weather plants.

  13. Using clean-coal technologies to "repower" existing factories promises ultimately a substantial reduction of polluting emissions, and will affect the full range of pollutants implicated in acid rain. The strategy of using these technologies could cut sulfur dioxide emission by more then 80 percent and nitrogen oxide emissions by more then 50 percent.

  (E) The choice of technologies in factories could reduce the formation of noxious ozone in the troposphere.

  14. Joshua Smith's new novel was criticized by the book editor for The Daily Standard as implausible. That criticism, like so many other criticisms from the same source in the past , is completely unwarranted. As anyone who has actually read the novel would agree.

  15. J.J. Thomson, the discoverer of the electron and a recipient of the Nobel Price in physics, trained many physicists, among them seven Nobel Price winners, 32 fellows of the Royal Society of London, and 83 professors of physics.

  Which one of the following is an assumption on which the argument depends?

  (A) J.J. Thomson was an internationally known physicist and scientists came from all over the world to work with him

  (B) All the scientists trained by were renowned for their creative scientific research

  (C) At least one of the eminent scientists trained by J.J. Thomson was not a creative researcher before coming to study with him

  17. From a book review: The authors blithely claim that there are "three basic ways to store energy: as heat, as electricity or as kinetic energy" However, I can not call to mind any affective ways to store energy as electricity, whereas any capable student of physics could readily suggest a few more ways to store energy : chemical , gravitational, nuclear

  (D) What needs to be considered is not whether various ways to store energy are basic but whether they are effective

  (E) Except possibly for electricity all ways to store energy are equally effective and therefore equally basic

  18.There is no mystery as to why figurative painting revived in the fate 1970s.People want to look at recognizable images. Sorting out art theories reflected in abstract paintings
