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 questions. You should not make assumptions that are by blacken the corresponding space on your answer sheet.

1. When politicians resort to personal atacks many editortalists criticize thest attacks but most voters pay them scant attention. Eeveryone knows such attacks will end after election day, and politicians can be excused for mudslinging. Political commentators, however, cannot be. Political commentators should be engaged in sustained and senous debate about ideas and policies. In such a context personal attacks on opponents serve not to beat those opponents but to cut off the debate.

Which of the following most accurately states the main point of the argument?

(A) Dersonal attacks on opponets serve a usuful purpose for politicians.
(B) Political commentators should not resort to personal attacks on their   opponents.
(C) Editonalists are right to criticize politicians who resort to personal attacks   on their opponents.
(D) The purpose of serious debate about ideas and policies is to counteract the   effect of personal attacks by politicians.
(E) Voters should be concerned about the personal attacks politicians make on   each other.

2. Throughout the Popoya Islands community pressure is exerted on people who win the national lottery to share their good fortune with their neighbors. When people living in rural areas win the lottery they invariably throw elaborate neighborhood feasts, often wiping, out all of their lottery winmmings. However, in the cities, lottery winners frequently use their winnings for their own personal investment rather than sharing their good fortune with their neighbors.

Which one of the following true, contributes most to an explanation of the difference between the behavior of lottery winners in rural areas and those in cities?

(A) Twice as many Popoyans live in rural areas as live in the city.
(B) Popoyan city dwellers tend to buy several lottery tickets at a time, but they   buy tickets less frequently than do rural dwellers.
(C) Lottery winners in rural areas are notified of winning by public posting of lists   of winners, but notification in the city is by private mail.
(D) Families in rural areas in the Popoyas may contain twelve or foruteen   people, but city families average six or seven.
(E) Twice as many lottery tickets are sold in rural areas as are sold in the city.

3. A new medication for migraine seems effective, but there is concern that the medication might exacerbate heart disease. If patiens with heart disease take the medication under careful medical supervision. however, harmful side effects can definitely be averted. The concern about those side effects is thus unfounded.

The argument depends on which one of the following assumptions?

(A) The new medication actually is effective when taken by patients with heart   disease.
(B) No migraine sufferers with heart disease will take the new medication   except under careful medical supervision.
(C) Most migraine sufferers who have taken the new medication in trials also   had heart disease
(D) The new medication has various other side effects, but none as serious as   that of exacerbating heart disease.
(E) The new medication will displace all migrame medicztions currently being   used.

4. The highest-ranking detectives in the city s police department are also the most adept at solving crimes. Yet in each of the past ten years. the average success rate for the city s highest-ranking detectives in solving crimnal cases has been no higher than the average success rate for its lowest-ranking detectives.

Which one of the follwing, if true, most helps to resolve the apparent paradox?

(A) The detectives who have the highest success rate in solving criminal cases   are those who have worked as detectives the longest.
(B) It generally takes at least ten years for a detective to rise from the lowest to   the highest ranks of the city s detective force.
(C) Those detectives in the police department who are the most adept at solving   criminal cases are also those most likely to remain in the police   department.
(D) The police department generally gives the criminal cases that it expects to   be the easiest to solve to its lowest-ranking detectives.
(E) None of the lowest-ranking detectivesin the police department had   experiecne in solving critninal cases prior to joining the police deparment.

5. Imgation runoff from neighboring farms may well have increased the concentration of phosphorus in the local swamp above previous levels, but the claim that the increase in phosphorus is harming the swamp s native aquatie wildlife is false: the phospborus concentration in the swamp is actually less than that found in certain kinds of bottled water that some people drink every day.

The argument is vulnerable to criticism on the ground that it

(A) makes exaggerations in formulating the claim against which it argues
(B) bases its conclusion on two contradictiry claims
(C) relies on evidence the relevance of which has not been established
(D) concedes the very point that it argues against
(E) makes a generalization that is unwarranted because the sources of the data   on which it is based have not been specified.

6. Copyright laws protect the rights of writers to profits earned from their writings. whereas patent laws protec: inventors rights to profits earned from their inventions In jawade, when computer-software writers demanded that their rights to profit be protected, the courts determined that information written for a machine does not fit into either the copyright or the patent category. Clearly, therefore, the profit rights of computer-software writers remain unprotected in Jawade.

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

(A) Computer-software writers are not an influential enough group in Jawade for   the government to consider modifying existing copyright laws in order to   protect this group s profit rights.
(B) No laws exist, other than copyright laws and patent laws, that would protect   the profit rights of computer-software writers in Jawade.
(C) Most of the computer software used in Jawade is imported from other   countries.
(D) Computer software is more similar to writings covered by copyright laws   than it is to inventions covered by patent laws.
(E) Copyright laws and patent laws in Jawade have not been modified since   their original adoption.

7. Brownlea s post office must be replaced with a larger one. The present one cannot be expanded. land near the present location in the center of town is more expensive than land on the outskirts of town. Since the cost of acquiring a site is a significant part of the total construction cost, the post office clearly could be built more cheaply on the outskirts of town.

Which one of the following, if true, most seriously undermines the argument s stated conclusion?

(A) The new post office will have to be built in accordance with a demanding   new citywide building code.
(B) If the new post office is built on the outskirts of town, it will require a parking   lot, but if sited near the present post office it will not.
(C) If the new post office is built on the outskirts of town, current city bus routes   will have to be expanded to provide access.
(D) If the new post office is built on the outskirts of town, residents will make   decreased use of post office boxes, with the result that mail carriers will   have to deliver more mail to homes.
(E) If the new post office is built near the center of town, disruptions to city   traffic would have to be minimized by taking such steps as doing some   construction work in stages at night and on weekends.

8. in the past, the railroads in Ostronia were run as regional monopelies and opeerated with little regard for what customers wanted. In recent years, with improvements to the Ostronian national highway network the railroad companies have faced heavy competition from longdistance trucking companies. But because of government subsidies that have permitted Ostronian railroad companies to operate even while incuring substantial losses, the companies continie to disregard customers needs and desires.

If the statements above are true, which one of the following must also be true on the basis of them?

(A) If the government of Ostronia ceases to subsidize railroad companies. few of   those companies will continue to operate.
(B) Few companies in Ostronia that have received subsidies from the   government have taken the needs and desires of their customers into   account.
(C) Without government subsidies, railroad companies in Ostronia would have   to increase the prices they charge their customers.
(D) The transportation system in Ostronia is no more efficient today than it was   in the past.
(E) In recent years, some companies in Ostronia that have had little regard for   the desires of their customers have nonetheless survived.

9. Although Damon had ample time carlier in the month to complete the paper he is scheduled to present at a professional conference tomorrow morning he repeatedly put off doing it. Damon could still get the paper ready in time, but only if he works on it all evening without interruption. However, his seven-year-old daughter s tap-dance recital takes place this evening and Damon had promised both to attend and to take his daughter and her friends out for ice cream afterward. Thus, because of his procrastination. Damon will be forced to choose between his professional and his farmily responsibilities.

The argument proceeds by

(A) providing evidence that one event will occur in order to establish that an   altemative event cannot occur
(B) showing that two situations are similar in order to justify the claim that   someone with certain responsibilities in the first situation has similar   responsibilities in the second situation
(C) invoking sympathy for someone who finds himself in a dilemma in order to   excuse that person s failure to meet all of his responsibilities
(D) making clear the extent to which someone s actions resulted in harm to   others in order to support the claim that those actions were irresponsible
(E) demonstrating that two situations cannot both occur by showing that   something necessary for one of those situations is incompatible with   something necessary for the other situation

10. The increase in the price of jet fuel is due to a sharp decrease over the past year in the supply of jet fuel available relative to demand. Nonetheless, the amount of jet fuel available for sale is larger today than it was last year.

(A) The demand for jet fuel has increased over the past year.
(B) The fuel efficiency of jet engines has increased over the past year.
(C) The number of jet airline flights has decreased over the past year.
(D) The cost of refining petroleum for jet fuel has increased over the past year.

Questions 11-12

  Nan Government subsidies have been proposed in Cariana to encourage farmers in Rochelle, the country s principal agricultural region, to implement certain new farming techniques Unless these techniques are implemented erosion of productive topsoil cannot be controlled Unfortunately farmers cannot afford to shoulder the entire cost of the new techniques, which are more expensive than those currently used Therefore, without subsidies agricultural output in Rochelle will inevitably decline

  Betty But erosion in Rochelle is caused by recurring floods, which will end next year once Cariana completes the hydroelectric dam it is building across the region s major river Therefore, Rochelle s total agricultural output will stabilize at its present level even without subsidres.

11. Which one of the following is an assumption on which Betty s argument depends?

(A) Building a dam across Rochelle s major river will not reduce any recurrent   flooding that occurs in regions of Cariana other than Rochelle.
(B) The new farming techniques that must be implemented to control soil   erosion in Rochelle are not well suited to other regions of Cariana
(C) The current yearly output, if any from Rochelle s land that will be   permanently under water once the dam is completed will at least be   matched by additional yearly output from Rochelle s remaining land
(D) The cost to the government of Cariana to operate the hydroelectric dam will   not be greater than the projected cost of subsidizing the farmers of   Rochelle in the implementation of the new farming techniques
(E) The government of Cariana has sufficient financial resources both to   subsidize its farmers implementation of new farming techniques and to   operate a hydroelectric dam.

12. Betty uses which one of the following argumentative techniques in countering Alan s argument?

(A) showing that one premise in Alan s argument is inconsistent with another   premise in his argument
(B) making additional claims that, if correct undermine a premise in Alan s   argument
(C) demonstrating that Alan s conclusion is true but not for the reasons Alan   gives to support it
(D) presenting evidence indicating that the policy Alan argues in favor of would   have damaging consequences that outweigh its positive consequences.
(E) pointing out that Alan s argument mistakenly identifies something as the   cause of a trend when it is really an effect of that trend

13. Astronomers have long thought that the irregularity in the orbit of the planet Neptune was adequately explained by the gravitational pull exerted on Neptune by the planet Pluto The most recent observations of Pluto, however indicate that this planet is much too small to exert the amount of gravitational pull on Neptune that astronomers once thought it did

If the statements above are true, they provide the most support for which one of the following?

(A) Neptune is somewhat larger than scientists once believed it to be
(B) The orbit of Neptune is considerably more irregular than scientists once   thought it was
(C) There exists another as yet undiscovered planet with an orbit beyond that of   Pluto
(D) The gravitational pull of Pluto is not the sole cause of Neptune s irregular   orbit

Questions 14-15

  In most corporations the salaries of executives are set by a group from the corporation s board of directors. Since the board s primary mission is to safeguard the economic health of the corporation rather than to make its executives rich, this way of setting executives salaries is expected to prevent excessively large salaries But , clearly this expectation is based on poor reasoning After all, most members of a corporation s board are themselves executives of some corporation and can expect to benefit from setting generous benchmarks for executives salaries.

14. The point made by the author is that the most common way of setting executives salaries might not keep those salaries in bounds because

(A) most corporals exectives, thanks to their generous salaries, are not   financially dependent on money earned as board members
(B) most corporals executives might be less generous in setting their own   salaries than the board members actually setting them are
(C) many board members might let their self-interest as executives interfere   with properly discharging their role as board members in setting executives   salaries
(D) many board members who set executives salaries unreasonably high do so   because they happen to be on the board of a corporation of which they   expect later to become executives
(E) many board members are remunerated generously and wish to protect this   source of income by pleasing the executives to whom they owe their   appointments on the board

16. Consumer advocate One advertisement that is deceptive, and thus morally wrong, states that gram for gram, the refined sugar used in out chocolate pies is no more fattening than the sugars found in fruits and vegetables" This is like trying to persuade someone that chocolate pies are not fattening by saying that, calorie for calorie they are no more fattening than celery True but it would take a whole shopping cart full of celery to equal a chocolate pie s worth of calories

  A dvertiser This advertisement cannot be called deceptive. It is, after all true

  Which one of the following principles, if established would do most to support the consumer advocate s position against the advertiser s response?

(A) It is morally wrong to seek to persuade by use of deceptive statements
(B) A true statement should be regarded as deceptive only if the person making   the statement believes it to be false, and thus intends the people reading or   hearing it to acquire a false belief.
(C) To make statements that impart only a small proportion of the information in   one s possession should not necessarily be regarded as deceptive
(D) It is morally wrong to make a true statement in a manner that will deceive   hearers or readers of the statement into believing that it is false
(E) a true statement should be regarded as deceptive if it is made with the   expectation that people hearing or reading the statement will draw a false   conclusion from it.

17. Members of the Amazonian Akabe people commonly take an early-morning drink of a tea made from the leaves of a forest plant. Although they greatly enjoy this drink, at dawn they drink it only in small amounts. Anthropologists hypothesize that since this tea is extraordinarily high in caffeine, the explanation for the Akabe s not drinking more of it at dawn is that high caffeine intake would destroy the surefootedness that their daily tasks require.

Which one of the following, if true, most seriously calls the anthropologists explanation into question?

(A) The drink is full of nutrients otherwise absent from the Akabe diet
(B) The Akabe also drink the tea in the evening, after their day s work is done.
(C) The leaves used for the tea contain a soluble narcotic.
(D) Akabe children are introduced to the tea in only a very weak form.
(E) When celebrating, the Akabe drink the tea in large quantities.

18. All of the cargo ships of the Blue Star Liner are over 100 meters long, and all of its passenger ships are under 100 meters long. Most of the ships of the Blue Star Line were built before 1980. All of the passenger and cargo ships of the Gold Star Line were built after 1980, and all are under 100 meters long. The dockside facilities of Port Tropica, which is open only to ships of these two lines, can accommodate only those ships that are less than 100 meters long. The S.S. Coral is a cargo ship that is currently docked at Port Tropica

19. Spectroscopic analysis has revealed the existence of frozen nitrogen, methane, and carbon monoxide on the surface of Pluto. Such ices have a tendency to vaporize, producing an atmosphere. Since the proportion of any gas in such an atmosphere depends directly on how readily the corresponding ice vaporizes, astronomers have concluded that the components of Pluto s atmosphere are nitrogen, carbon monoxide, and methane, in order of decreasing abundance.

The astronomers argumetn relies on which one of the following assumptions?

(A) There is no more frozen nitrogen on the surface of Pluto than there is either   frozen carbon monoxide or methane.
(B) Until space probes reach Pluto, direct analysis of the atmosphere is   impossible.
(C) There is no frozen substance on the surface of Pluto that vaporizes more   readily than methane but less readily than carbon monoxide.
(D) Nitrogen is found in the atmosphere of a planet only if nitrogen ice is found   on the surface of that planet.
(E) A mixture of nitrogen, carbon monoxide, and methane is characteristic of   the substances from which the Solar System formed.

20. Ann will either take a leave of absence from Technocomp and return in a year or else she will quit her job there; but she would not do either one unless she were offerend a one-year teaching fellowship at a prestigious university. Technocomp will allow her to take a leave of absence if it does not find out that she has been offered the fellowship, but not otherwise, Therefore, Ann will quit her job at Tedhnocomp only if Technocomp finds out she has been oftered the fellowship.

Which one of the following, if assumed, allows the conclusion above to be properly drawn?

(A) Technocomp will find out about Ann being offered the fellowship only if   someone informs on her.
(B) The reason Ann wants the fellowship is so she can quit her job at   Technocomp.
(C) Technocomp does not allow any of its employees to take a leave of   absence in order to work for one of its competitors.
(D) Ann will take a leave of absence if Technocomp allows her to take a leave of   absence.
(E) Ann would be offered the fellowship only if she quit her job at Technocomp.

21. If a mechanical aerator is installed in a fish pool, the water in the pool can be properly aerated. So, since John s fish pool does not have a mechanical aerator, it must be that his pool is not properly aerated. Without properly aerated water, fish cannot thrive. Therefore, any fish in John s fish pool will not thrive.

Which one of the following arguments contains an error of reasoning that is also contained in the argument above?

(A) If alum is added to pickle brine, brine can replace the water in the pickles.   Therefore, since Paula does not add alum to her pickle brine, the water in   the pickles cannot be replaced by brine. Unless their water is replaced with   brine, pickles will not stay crisp. Thus, Paula s pickles will not stay crisp.
(B) If pectin is added to jam, the jam will gel. Without a setting agent such as   pectin, jam will not ge. So in order to make his jam gel. Harry should add a   setting agent such as pectin to the jam.
(C) If stored potatoes are not exposed to ethylene the potatoes will not sprout.   Beets do not release ethylene. Therefore, if Sara stores her potatoes   together with beets, the potatoes will not sprout.
(D) If a carrot patch is covered with mulch in the fall. the carrots can be left in   the ground until spring Without a mulch cover, carrots stored in the ground   can suffer frost damage. Thus, since Kevin covers his carrot patch with   mulch in the fall, the carrots can safely be left in the ground.
(E) If tomatoes are not stored in a dark place, their seeds sometimes sprout.   Sprouted seeds can make tomatoes inedible. Therefore, since Maria does   not store her tomatoes in a dark place some of Maria s tomatoes could be   inedible.

Questions 22-23

  Antinuclear activist: The closing of the nuclear power plant is a victory for the antinuclear cause. It also represents a belated acknowledgment by the power industry that they cannot operate such plants safely.

  Nuclear power plant manager : It represents no such thing. The availability of cheap power from nonnuclear sources. together with the cost of mandated safety inspections and safety repairs, made continued operation uneconomic. Thus it was not safety considerations but economic considerations taht dictated the plant s closing.

[NextPage]

 

22. The reasoning in the manager s argument is flawed because the argument

(A) fails to acknowledge that the power industry might now believe nuclear   power plants to be unsafe even though this plant was not closed for safety   reasons
(B) overlooks the possibility that the soruces from which cheap power is   available might themselves be subject to safety concerns
(C) mistakes the issue of what the closure of the plant represents to the publie   for the issue of what the managers reason for the closure were
(D) takes as one of its premises a view about the power industry s attitude   toward nuclear safety that contradicts the activist s view
(E) counts as purely economic considerations some expenses that arise as a   result of the need to take safety precautions

23. Which one of the following if true, most strongly supports the activist s claim of victory?

(A) The plant had reached the age at which its operating license expired.
(B) The mandate for inspections and repairs mentioned by the manager was   recently enacted as a result of pressure from antinuclear groups.
(C) The plant would not have closed if cheap power from nonnuclear sources   had not been available.
(D) Per unit of electricity produced the plant had the highest operating costs of   any nuclear power plant.
(E) The plant that closed had been able to provide backup power to an electrical   network when parts of the network became overloaded.

Questions 24-25

  Statistician Changes in the Sun s luminosity correlate exceedingly well with average land temperatures on Earth. Clerly—and contrary to accepted opinion among meteorologists—the Sun s lumionsity essentially controls land temperatures on Earth.

  Meteorologist: I disagree Any professional meteorologist will tell you that in a system as complicated as that giving rise to the climate, no significant aspect can be controlled by a single variable

24. The rejection by the meteorologist of the statistician s conclusion employs which one of the following techniques of argumentation?

(A) supporting a conclusion about a specific case by invoking a relevant   generalization
(B) producint a single counterexample that establishes that a generalization is   false as state
(C) reanalyzing a correlation as reflecting the multiple effects of a single cause
(D) rejecting a conclusion because it is a proposition that cannot be   experimentally tested
(E) pointing out that potentially unfavorable evident has been systematically   neglected

25. The reasoning in the meteorologist s counterargument questionable because that argument

(A) rejects a partial explanation, not because it is incorrect but only because it   is not complete
(B) fails to distinguish phenomena that exist independently of a particular   system from phenomena that exist only as part of the system.
(C) calls into question the existence of a correlation when the only real issue is   that of how to interpret the correlation
(D) dismisses a hypothesis on the grounds that is fail to deal with anymatters   of scientific significant
(E) appeals to the authoritativeness of an opinion without evaluating the merit of   a putative counterexample
