  24 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 me response that most accurately and completely answers the question. You should not make assumptions that are bycommonsense standards implausible superfluous or incompatible with the passage. After you have chosen the best answer blacken the corresponding space on your answer sheet.

1. Director of Ace Manufacturing Company: Our management consultant proposes that we reassign staff so that all employees are doing both what they like to do and what they do well. This, she says, will "increase productivity by fully exploiting our available resources." But Ace Manufacturing has a long-standing commitment not to exploit its workers. Therefore, implementing her recommendations would cause us to violate our own policy.
  (A) failing to distinguish two distinct senses of a key term
(B) attempting to defend an action on the ground that it is frequently carried out

  (C) defining a term by pointing to an atypical example of something to which the   term applies

  (D) drawing a conclusion that simply restates one of the premises of the   argument

  (E) calling something by a less offensive term than the term that is usually used   to name that thing

  2. A large number of drivers routinely violate highway speed limits. Since driving at speeds that exceed posted limits is a significant factor in most accidents, installing devices in all cars that prevent those cars from traveling faster than the speed limit would prevent most accidents.

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

  (A) A person need not be a trained mechanic to install the device properly.

  (B) Most accidents are caused by inexperienced drivers.

  (C) A driver seldom needs to exceed the speed limit to avoid an accident when   none of the other drivers involved are violating the speed limit.
 (D) Most drivers who exceed the speed limit do so unintentionally.

  (E) Even if the fines for speed-limit violations were increased, the number of   such violations would still not be reduced.

  3. In a recession, a decrease in consumer spending causes many businesses to lay off workers or even to close, Workers who lose their jobs in a recession usually cannot find new jobs. The result is an increase in the number of people who are jobless. Recovery from a recession is defined by an increase in consumer spending and an expansion of business activity that creates a need for additional workers. But businesspeople generally have little confidence in the econnomy after a recession and therefore delay hiring additional workers as long as possible.

  The statements above, if true, provide most support for which one of the following conclusions?

  (A) Recessions are usually caused by a decrease in businesspeople’s   confidence in the economy.

  (B) Governmental intervention is required in order for an economy to recover   from a recession.
 (C) Employees of businesses that close during a recession make up the   majority of the workers who lose their jobs during that recession.

  (D) Sometimes recovery from a recession does not promptly result in a   decrease in the number of people who are jobless.

  (E) Workers who lose their jobs during a recession are likely to get equally   good jobs when the economy recovers.
  4. Scientists analyzine air bubbles that had been trapped in Antarctic ice during the Earth’s last ice age found that the ice-age atmosphere had contained unusually large amounts of ferrous material and surprisingly small amounts of carbon dioxide. One scientist noted that alage absorb carbon dioxide from the atmosphere. The scientist hypothesized that the ferrous material, which was contained in atmospheric dust, had promoted a great increase in the population of Antarctic algae such as diatoms.

  Which one of the following, if true, would most seriously undermine the scientist’s hypothesis?

  (A) Diatoms are a microscopie form of algae that has remained largely   unchanged since the last ice age.
  (B) Computer mosels suggest that a large increase in ferrous material today   could greatly promote the growth of oceanic alage.

  (C) The dust found in the air bubbles trapped in Antarctic ice contained other   minerais in addition to the ferrous material.

  (D) Sediment from the ocean floor near Antarctica refiects no increas, during   the last ice age, in the rate at which the shells that diatoms leave when   they die accumulated.

  (E) Alage that currently grow in the oceans near Antarctica do not appear to be   harmed by even a large increase in exposure to ferrous material.

  5. Adults who work outside the home spend, on average, 100 minutes less time each week in preparing dinner than adults who do not work outside the home. But, contrary to expectation, comparisons show that the dinners eaten at home by the two groups of adults do not differ significantly with respect to nutritional value, variety of menus, or number of courses.
  Which one of the following, if true, most helps to resolve the apparent discrepancy in the information above?
  (A) The fat content of the dinners eaten at home by adults who do not work   outside the home is 25 percent higher than national guidelines recommend

  (B) Adults who do not work outside the home tend to prepare breakfast more   often than adults who work outside the home.

  (C) Adults who work outside the home spend 2 hours less time per day on all   household responsibilities, including dinner preparation, than do adults who   do not work outside the home.

  (D) Adults who work outside the home eat dinner at do home 20 percent less   often than do adults who not work outside the home.

  (E) Adults who work outside the home are less likely to plan dinner menus well   in advance than are adults who do not work outside the home.

  The regulator responds to the legislator’s criticism by 

  (A) shifting the blame for the scandals to the legislature 

  (B) providing information that challenges the conclusion drawn by the legislator 

  (C) claiming that compliance with the legislature’s mandate would have been an   insufficient response 
 (D) repharasing the legislator’s conclusion in terms more favorable to the   regulator 

  (E) showing that the legislator’s statements are self-contradictory. 

  7. A commonly accepted myth is that left-handed people are more prone to cause accidents than are right-handed people. But this is, in fact, just a myth, as is indicated by the fact that more household accidents are caused by right-handed people than are caused by left-handed people. 

  The reasoning is flawed because the argument. 

  (A) makes a distinction where there is no real difference between the things   distinguished 

  (B) takes no account of the relative frequency of left-handed people in the   population as a whole 

  (C) uses the word "accidents" in two different senses 

  (D) ignores the possibility that some hosehold accidents are caused by more   than one person 

  (E) gives wholly irrelevant evidence and simply disparages an opposing position   by calling it a "myth". 
  Questions 8-9 

  Ornithologist: The curvature of the claws of modern tree-dwelling birds enables them to perch in trees. The claws of Archeopteryx, the earlies known birdlike creature, show similar curvature that must have enabled the creature to perch on tree limbs. Therefore, Archeopteryx was probably a tree-dwelling creature. 

  Paleontologist: No, the ability to perch in trees is not good evidence that Archeopteryx was a tree-dwelling bird.Chickens also spend time perched in trees, yet chickens are primarily ground-dwelling. 

  8. In responding to the ornithologist’s hypothesis that Archeopteryx was tree-dwelling, the paleontologist 

  (A) questions the qualifications of the ornithologist to evaluate the evidence 

  (B) denies the truth of the claims the ornithologist makes in support of the   hypothesis 

  (C) uses a parallel case to illustrate a weakness in the ornithologist’s argument 

  (D) shows that the hypothesis contradicts one of the pieces of evidence used to   support it 

  (E) provides additional evidence to support the ornithologist’s argument 
  9. Which one of the following is an assumption on which the ornithologist’s reasoning depends? 

  (A) Modern tree-dwelling birds are the direct descendants of Archeopteryx. 

  (B) Archeopteryx made use of the curvature of its claws. 

  (C) There have never been tree-dwelling birds without curved claws. 

  (D) Archeopteryx was in fact the earliest birdlike creature. 

  (E) The curvature of the claws is the only available evidence for the laim that   Archeopteryx was tree-dwelling.

  10. There are rumors that the Premier will reshuffle the cabinet this week. However, every previous reshuffle that the Premier has made was preceded by meetings between the Premier and senior cabinet members. No such meetings have occurred or are planned. Therefore the rumors are most likely false. 
   
  Which one of the following most accurately expresses a principle of reasoning employed by the argument? 

  (B) A hypothesis is undermined when a state of affairs does not obtain that would be expected to obtain if the hypothesis were true. 
(C) It is possible for a hypothesis to be false even though it is supported by all the available data. 

  (D) Even if in the past a phenomenon was caused by particular circumstances, it is erroneous to assume that the phenomenon will recur only under the   circumstances in which it previously occured. 

  (E) If two statements are known to be inconsistent with each other and if one of  the statements is known to be false, it cannot be deduced from these known facts that the other statement is true.

  Questions 11-12
  Carl: Researchers who perform operations on animals for experimental purposes are legally required to complete detailed pain protocols indicating whether the animals will be at risk of pain and, if so, what steps will be taken to minimize or alleviate it. Yet when human beings undergo operations, such protocols are never required. If lawmakers were as concerned about human beings as they seem to be about animals, there would be pain protocols for human beings too. 
Debbie: But consider this: a person for whom a doctor wants to schedule surgery can simply be told what pain to expect and can then decide whether or not to undergo the operation. So you see, pain protocols are unnecessary for human beings.

  11. Debbie attempts to counter Carl’s argument by.

  (A) showing that one of the claims on which Carl bases his conclusion is   inaccurate

  (B) pointing out a relevant difference to undermine an analogy on which Carl   bases his conclusion

  (C) claiming that Carl’s argument should be rejected because it is based on an   appeal to sentimentality rather than on reasoned principles

  (D) drawing an analogy that illustrates a major flaw in Car’s argument

  (E) offering a specific example to demonstrate that Carl’s argument is based on   a claim that can be neither confirmed nor disproved.

  12. Which one of the following, if true, most seriously weakens the argument made by Debbie in response to Car’s argument?

  (A) Not all operations that are performed on human beings are painful.
 (B) Some experimentation that is now done on animals need not be done at all.

  (C) Preparing pain protocols is not a time-consuming or costly procedure.

  (D) Some surgical operations performed on infants are painful.

  (E) Unalleviated pain after an operation tends to delay the healing process.

  13. A company with long-outstanding bills owed by its customers can assign those bills to collection agency that pays the company a fraction of their amount and then tries to collect payment from the customers. Since these agencies pay companies only 15 percent of the total amount of the outstanding bills, a company interested in reducing losses from long-outstanding bills would be well advised to pursue its debtors on its own.

  The argument depends on the assumption that

  (A) a company that prusues its debtors on its own typically coliects more than   15 percent of the total amount of the long-outstanding bills that it is owed

  (E) unless most of the customers of a company pay their bills, that company in   the long run will not be profitable.
14. Herbalist: Many of my customers find that their physical coordination improves after drinking juice containing certain herbs. A few doctors assert that the herbs are potentially harmful, but doctors are always trying to maintain a monopoly over medical therapies. So there is no reason not to try my herb juice.

  The reasoning in the herbalist’s argument is flawed because the argument
  (A) attempts to force acceptance of a claim by inducing fear of the   consequences of rejecting that claim

  (B) bases a conclusion on claims that are inconsistent with each other

  (C) rejects a claim by attacking the proponents of the claim rather than   addressing the claim itself

  (D) relies on evidence presented in terms that presuppose the truth of the claim   for which the evidence is offered.

  (E) mistakes the observation that one thing happens after another for proof that   the second thing is the result of the first

  Which one of the following is an assumption required by the argument?
 (A) Most poachers who are discouraged from hunting rhinoceroses are not   likely to hunt other animals for their horns.

  (B) At least some rhinoceroses whose horns are periodically trimmed off will be   able to attract mates.

  (C) Poachers hunt at least some immature rhinoceroses whose horns have not   yet started to develop.

  (D) The demand for rhinoceros horns will remain constant even if the supply   decreases after the periodic trimming-off of the rhinoceros horns has   begun.

  (E) Rhinoceroses whose horns have been trimmed off are unable to defend   themselves against predators.

  16. Motorcoach driver: Professional drivers spend much more time driving. on average, than do other people and hence are more competent drivers than are other, less experienced drivers. Therefore, the speed limit on major highways should not be reduced, because that action would have the undesirable effect of forcing some people who are now both law-abiding and competent drivers to break the law.

  The point at issue between the motorcoach driver and the police officer is whether.
(A) it would be desirable to reduce the speed limit on major highways

  (B) professional drivers will drive within the legal speed limit if that limit is   reduced

  (C) reducing the speed limit on major highways would cause some professional   drivers to break the law.

  (D) professional drivers are more competent drivers than are other, less   experienced drivers.

  (E) all drivers wish to drive within the speed limit

  17. People cannot devote themselves to the study of natural processes unless they have leisure, and people have leisure when resources are plentiful, not when resources are scarce. Although some anthropologists claim that agriculture, the cultivation of crops, actually began under conditions of drought and hunger, the early societies that domesticated plants must first have discovered how the plants they cultivated reproduced themselves and grew to maturity. These complex discoveries were the result of the active study of natural processes.

  The argument is structured to lead to the conclusion that 
  (A) whenever a society has plentiful resources, some members of that society   devote themselves to the study of natural processes.

  (B) plants cannot be cultivated by someone lacking theoretical knowledge of the   principles of plant generation and growth

  (C) agriculture first began in societies that at some time in their history had   plentiful resources

  (D) early agricultural societies knew more about the natural sciences than did   early nonagriculatural societies

  (E) early societies could have discovered by accident how the plants they   cultivated reproduced and grew.

  18. In the past decade, a decreasing percentage of money spent on treating disease X went to pay for standard methods of treatment, which are known to be effective though they are expensive and painful. An increasing percentage is being spent on nonstandard treatments. which cause little discomfort. Unfortunately, the nonstandard treatments have proved to be ineffective. Obviously, less money is being spent now on effective treatments of disease X than was spent ten years ago
  Which one of the following, if assumed, allows the conclusion above to be properly drawn?

  (A) Varieties of disease X requiring expensive special treatment have become   less common during the past decade.

  (B) Nonstandard methods of treating disease X are more expensive now than   they were a decade ago.

  (C) Of total medical expenditures, the percentage that is due to treatment of   disease X increased during the past decade.

  (D) Most of the money spent on treating disease X during the last decade went   to pay for nonstandard treatments.

  (E) Tht total amount of money spent on treating disease X slowly declined   during the past decade.


  Which one of the following most logically completes the argument?

  (A) become larger in size yet still be of uniform thickness.

  (B) flow toward the point at which the pressure of the object is greatest

  (C) compress, although not as much as a piece of steel would

  (D) divide into exactly two pieces that are equal in neither size nor shape to the   original piece of glass
 (E) be thinner in the portion of the glass that is under the pressure of the object   than in those portions of the glass that are not under that pressure

  20. Anyone who insists that music videos are an art form should also agree that television gave rise to an art form, since televison gave rise to music videos.

  The parttern of reasoning displayed in the gragument above most closely parallels that displayed in which one of the following?

  (A) Anyone who claims that all vegetalbes are nutritious should also agree that   some vegetables are harmful if eaten in large quantities.

  (B) Anyone who holds that avocados are a fruit should also hold that pound   cake is lower in fat than some fruit, since pound cake is lower in fat than   avocados.

  (C) Anyone who dislikes tomatoes should also agree that some people do like   tomatoes, if that person agrees that no laste is universal.

  (D) A person who eats a variety of vegetables is probably well nourished, since   most people who eat a variety of vegetables generally eat well-balanced   meals.
(E) A person who claims to prefer fruit to vegetables should also prefer cake to   bread, since fruit is sweeter than vegetables and cake is sweeter than   bread.

  21. Medieval Arabs had manuscripts of many ancient Greek texts, which were translated into Arabic when there was a demand for them. Medieval Arab philosophers were very interested in Arisototle’s Poetics, an interest that evidently was not shared by medieval Arab poets, because a poet interested in the Poetics would certainly have wanted to read Homer, to whose epics Aristotle frequently refers. But Homer was not translated into Arabic until modern times.

  Which one of the following, if true, most strongly supports the argument above?
  (A) A number of medieval Arab translators possessed manuscrips of the  Homeric epics in their original Greek.

  (B) Medieval AFrabic story cycles, such as the Arabian Nights, are in some  ways similar to parts of the Homeric epics.

  (C) In addition to translating from Greek, medieval Arab translators produced  Arabic editions of many works originally written in Indian languages and in   Persian.
  (D) Aristotle’s Poetics has frequently been cited and commented on by modern  Arab poets.

  (E) Aristotle’s Poetics is largely concerned with drama and dramatic works   were written and performed by medieval Arabs.

22. Congenial guests and a plentiful supply of good things to eat and drink will ensure a successful dinner party. Since Sylvia has prepared more than enough to eat and drink and her guests are all congenial people, her dinner party is certain to be a success.

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


  (A) The right ingredients, properly combined and baked in a reliable oven will   always produce a well-backed cake. Since Emily has properly combined   the right ingredients, her cake is certain to come but well if she bakes it in   a reliable oven.

  (B) If corn is baked with its husks on, the resulting dish will always be moist   and sweet. Since George wishes to ensure that the corn be plans to serve   is moist, he will be certain both to bake it and to leave its husks on.
 (C) Making pie dough using ice water and thoroughly chilling the dough before   rolling it out will ensure a flaky crust. Andrew thoroughly chilled his pie   dough before rolling it out, so, since he used ice water in making it, his pie   is certain to have a flaky crust. 

  (D) If soup is made with a well-seasoned meat stock and fresh ingredients, it   will always be welcome at dinner. Since to his meat stock Arnold added   only very fresh ingredients, the resulting soup is certain to be welcome at   dinner.

  (E) Fresh greens, carefully washed and served with light dressing, always   produce a refreshing salad, Since Tisha has developed an exceptionally   light dressing but never washes her fresh greens, no salad she serves will   be a refreshing one.
  The reasoning in the argument is vulnerable to the criticism that the argument does which one of the following?


  (A) It concludes that a certain opinion is correct on the grounds that it is held   by more people than hold the opposing view.

  (B) It rejects the judgment of the experts in an area in which there is no better   guide to the truth than expert judgment.

  (C) It rejects a proven means of accomplishing an objective without offering any   alternative means of accomplishing that objective.

  (D) It bases a firm conclusion about a state of affairs in the present on   somewhat speculative claims about a furture state of affairs.

  (E) It bases its conclusion on facts that could, in the given situation, have   resulted from causes other than those presupposed by the argument.

  24. The United States ranks far behind countries such as Sweden and Canada when it comes to workplace safety. In all three countries, joint labor-management committees that oversee workplace s afety conditions have been very successful in reducing occupational injuries. In the United States, such committees are found only in the few companies that have voluntarily established them. However, in Sweden and several Canadian provinces, joint safety committees are required by law and exist in all medium-sized and large workplaces.
 Which one of the following is supported by the information above?

  (A) The establishment of joint safety committees in all medium-sized and large   workplaces in the United States would result in a reduction of occupational   injuries.

  (B) A joint safety committee that is required by law is more effective at reducing   occupational injuries than is a joint safety committee that is voluntarily   established.

  (C) Workplace safety in Sweden and Canada was superior to that in the United   States even prior to the passage of laws requiring joint safety committees   in all medium-sized and large workplace.

  (D) Joint safety committees had been voluntarily established in most medium-  sized and large workplaces in Sweden and several Canadian provinces   prior to the passage of laws requiring such committees.

  (E) The United States would surpass Sweden and Canada in workplace safety if   joint safety committees were required in all medium-sized and lareg   workplaces in the United States.
