1. francis: pailure to become properly registered to vote prevents one-third of the voting-age citizens of lagonia from voting. if local election boards made the excessively cumbersome registration process easier. more people would register and vote
sharon: the high number of citizens not registered to vote has persisted despite many attempts to make registering easier. surveys show that most of these citizens believe that their votes would not make a difference. until that belief is changed, simplifying the registration process will not increase the percentage of citizens registering to vote
the main issue in dispute between francis and sharon is

2. advertisement anyone who thinks moisturizers are not important for beautiful skin should consider what happens to the earth, the skin of the word, in times of drought. without regular infusions of moisture the ground becomes lined and cracked and its lush loveliness fades away. thus your skin, too, should be protected from the protection provided by regular infusions of dewyfresh the drought-defying moisturizer.
the dewyfresh advertisement exhibits which one of the following errors of reasoning?
(a) it treats something that is necessary for bringing about a state of affairs as something that is sufficient to bring about that state of affairs
(b) it treats the fact that two things regularly occur together as proof that there is a single thing that is the cause of them both
(c) it overlooks the fact that changing what people think is the case does not necessarily change what is the case.
(d) it relies on the ambiguity of the term "infusion." which can designate either a process or the product of that process
(e) it relies on an analogy between two things that are insufficiently alike in the respects in which they would have to be alike for the conclusion to be supported.
questions 3-4
m: the greek alphabet must have been invented by some individual who knew the phoenician writing system and who wanted to have some way of recording homeric epies and thereby preserving expressions of a highly developed traditin of oral poetry.
p: your hypothesis is laughable! what would have been the point of such a person s writing homeric epices down? surely a person who knew them well enough to write them down would not need to read them, and no one else could read them, according to your hypothesis.

5. bacteria from food can survive for several days on the surface of plastic cutting boards, but bacteria can penetrate wooden cutting boards almost immediately, leaving the surface free of contamination. therefore, wooden cutting boards, unlike plastic cutting boards, need not be washed in order to prevent their conta-minating food that is cut on them; wiping them off to remove food debris is sufficient.
which one of the following is an a
ssumption on which the argument depends?
(a) washing plastic cutting boards does not remove all bacteria from the surface

(a) in rhiago, where asthmagon had been the most widely prescribed of the beta-2 agonists, the number of asthma deaths increased between 1981 and 1987.
(b) many of the patients under observation to whom asthmagon was administered had not previously taken a beta-2 agonist
(c) despite the growing concern about the drug many physicians in rhiago still prescribe asthmagon to asthma sufferers
(d) among the patients observed, only those who had very high cholesterol counts suffered side effects after taking asthmagon
(e) asthmagon increases the severity of asthma attacks in some people because the drug can cause damage to heart tissues

16. k, a research scientist, was accused of having falsified laboratory data. although the original data in question have disappeared, data from k s more recent experiments have been examined and clearly none of them were falsified. therefore, the accusation should be dismissed.
which one of the following contains questionable reasoning that is most similar to that in the argument above?
(a) l, an accountant, was charged with having embezzled funds from a client. the charge should be ignored, however, because although the records that might reveal this embezzlement have been destroyed, records of l s current clients show clearly that there has never been any embezzlement from them.

questions 17-18
the widespread staff reductions in a certain region s economy are said to be causing people who still have their jobs to cut back on new purchases as though they, too, had become economically distressed. clearly, however, actual spending by such people is undiminished, because there has been no unusual increase in the amount of money held by those people in savings accounts.
17. the argument in the passage proceeds by doing which one of the following?

20. when the pinecrest animal shelter, a charitable organization, was in danger of closing because it could not pay for important repairs, its directors appealed to the townspeople to donate money that would be earmarked to pay for those repairs. since more funds were ultimately donated than were used for the repairs the directors plan to donate the surplus funds to other animal shelters. but before doing so, the directors should obtain permission from those who made the donations
which one of the following priciples, if valid, most helps to justify the position advocated aboved above and yet places the least restriction on the allocation of funds by directors of charitable organizations?
(a) the directors of charitable organizations cannot allocate publicly solicited funds to any purposes for which the directors had not specifically carmarked the funds in advance
(b) people who solicit charitable donations from the public for a specific cause should spend the funds only on that cause or, if that becomes impossible, should dispose of the funds according to the express wishes of the donors.

21. the amount of electricity consumed in millville on any day in august is directly proportional to peak humidity on that day since the average peak humidity this august was three points higher than the average peak humidity last ausgust, it follows that more energy was consumed in millville this august than last august
which one of the following arguments has a pattern of reasoning most similar to the one in the argument above?
(a) the amount of art supplies used in any of the aesthetic institute s 25 classes is directly proportional to the number of students in that class. since in these classes the institute enrolled 20 percent more students overall last year than in the previous year mort art supplies were used in the institute s classes last year than in the provious year.
(b) the number of courses in painting offered by the aesthetic institute in any term is directly proportional to the number of students enrolled in the institute in that term. but the institute offers the same number of courses in sculpture each term. hence, the institute usually offers more courses in painting than in seulpture each term. hence, the institute usually offers more courses in painting than in sculpture.
(c) the number of new students enrolled at the aesthetic institute in any given year is directly proportional to the amount of advertising the institute has done in the previous year. hence, if the institute seeks to increase its student body it must increase the amount it spends on advertising
(d) the fees paid by a student at the aesthetic institute are didirectly proportional to the number of classes in which that student enrolls. since the number of students at the aesthetic institute is increasing, it follows that the institute is collecting a greater amount in fees paid by students than it used to
(e) the number of instructors employed by the aesthetic institute in any term is directly proportional to the number of classes offered in that term and also directly proportional to the number of students enrolled at the institute thus, the number of classes offered by the institute in any term is directly proportional to the number of students enrolled in that term.
22. letter to the editor: after baerton s factory closed, there was a sharp increase in the number of claims field for job-related injury compensation by the factory s former employees, hence there is reason to believe that most of those who filed for compensation after the factory closed were just out to gain benefits they did not deserve, and filed only to help them weather their job loss.
each of the following, if true, weakens the argument above except:
(a) workers cannot file for compensatio
n for many job-related injuries, such as hearings loss from factory noise, until they have left the job.
(b) in the years before the factory closed, the factory s managers dismissed several employees who had filed injury claims.
(c) most workers who receive an injury on the job file for compensation on the day they suffer the injury.
(d) workers who incur partial disabilities due to injuries on the job often donot file for compensation because they would have to stop working to receive compensation but cannot afford to live on that compensation alone.
(e) workers who are aware that they will soon be laid off from a job often become depressed, making them more prone to job-related injuries.
23. historians of north american architecture who have studied early nineteenth-century houses with wooden floors have observed that the boards used on the floors of bigger houses were generally much narrower than those used on the floors of smaller houses. these historians have argued that, since the people for whom the bigger houses were built were generally richer than the people for whom the smaller houses were probably once a status symbol, designed to proclaim the owner s wealth.
which one of the following, if true, most helps to strengthen the historians argument?
(a) more original floorboards have survived from big early nineteenth-century houses than from small early nineteenth-century houses than from small early nineteenth-century houses.
(b) in the early nineteenth century, a piece of narrow floorboard was not significantly less expensive than a piece of wide floorboard of the same length.
(c) in the early nineteenth century, smaller houses generally had fewer rooms than did bigger houses.
(d) some early nineteenth-century houses had wied floorboards near the walls of each room and narrower floorboards in the center, where the floors were usually carpeted.
(e) many of the biggest early nineteenth-century houses but very few small houses from that period had some floors that were made of materials that were considerably more expensive than wood, such as marble.
24. ethicist: a society is just when, and only when, first each person has an equal right to basic liberties, and second, inequalities in the distribution of income and wealth are not tolerated unles these inequalities are to everyone s advantage and are attached to jobs open to everyone.
which one of the following judgments most closely conforms to the principle described above?
(a) society s guarantees everyone equal right to basic liberties, while allowing inequalities in the distribution of income and wealth that are to the advantage of everyone. further, the jobs to which these inequalities are attached are open to most people, thus, society s is just.
(b) society s gives everyone an equal right to basic liberties, but at the expense of creating inequalities in the distribution of income and wealth. thus, society s is not just.
(c) society s allows inequalities in the distribution of income and wealth, although everyone benefits and these inequalities are attached to jobs that are open to everyone. thus, society s is just.
(d) society s distributes income and wealth to everyone equally, but at the expense of creating inequalities in the right to basic liberties. thus, society s is not just.
(e) society s gives everyone an equal right to basic liberties, and although there is an inequality in the distribution of income and wealth, the jobs, to which these inequalities are attached are open to all. thus, society s is just.
25. economist: in order to decied what to do about protecting the ozone layer, we must determine the monetary amount of the economic resources that we would willingly expend to protect it. such a determination amounts to a calculation of the monetary value of the ozone layer.
environmentalists argue that the ozone layer does not have a calculable monetary value. however, we would not willingly expend an amount equal to all of the world s economic resources to protect tha ozone layer so the ozone layer is demonstrably worth less than that amount. thus, the ozone layer has a calculable monetary value.
the reasoning in the economist s argument is flawed in that the argument
(a) uses evidence that the monetary value of a particular natural resource is less than a certain amount in order to establish that the monetary value of any natural resource is less than that amount
(b) presupposes that the ozone layer should not be protected and then argues to that claim as a conclusion
(c) takes advantage of an ambiguity in the term "value" to deflect the environmentalists charge
(d) gives no reason for thinking that merely establishing an upper limit on a certain monetary value would allow the calculation of that monetary value
(e) does not directly address t
he argument of the environmentalists.
26. columnist on the arts: my elected government representatives were within their rights to vote to support the arts with tax dollars. while funded by the government. however, some artists have produced works of art that are morally or aesthetically offensive to many taxpayers. nonetheless. my conclusion is that no taxpayers have been treated unjustly whose tax dollars are used to fund some particular work of art that they may find abominable.
which one of the following principles, if valid, most supports the columnist s argument?
(a) taxpayers should be allowed to decide whether a portion of their tax dollars is to be used to fund the arts.
(b) the funding of a particular activity is warranted if it is funded by elected representatives who legitimately fund that activity in general.
(c) elected representatives are within their rights to fund any activity that is supported by a majority of their constituents.
(d) those who resent taxation to subsidize offensive art should ovte against their incumbent government representatives.
(e) since taxpayers are free to leave their country if they disapprove of their representatives decisions they have no right to complain about arts funding.

12. people in the tourist industry know that excessive development of seaside areas by the industry damages the environment. such development also hurts the tourist industry by making these areas unattractive to tourists a fact of which people in the tourist industry are well aware people in the tourist industry would never knowingly do anything to damage the industry. therefore, they would never knowingly damage the seaside environment and people who are concerned about damage to the seaside people who are concerned about damage to the seaside environment thus have nothing to fear from the tourist industry
the reasoning in the arguments is most vulnerable to
(a) no support is provided for the claim that excessive development hurts the tourist industry
(b) that something is not the cause of a problem is used as evidence that it never coexists with that problem
(c) the argument shifts from applving a characteristie to a few membets of a group to applying the character istie to all members of that group

(d) television viewers are only interested in the people on television programs who have the same eating and drinking habits as they do
(e) the eating and drinking habits of people on television programs proclde health officerals with acctuate predictions about the foods and beverages that will become popular among television viewers
14. in an effort to boost sales during the summer months, which are typically the best for soft-drink sales foamy soda lowered its prices. in spite of this, however, the sales of foamy soda dropped during the summer months.
each of the following, if true, contributes to reconciling the apparent discrepancy indicated above except:
(a) the soft-drink industry as a whole experienced depressed sales during the summer months
(b) foamy soda s competitors lowered their prices even more drastically during the summer months
(c) because of an increase in the price of sweeteners the production costs of foamy soda rose during the summer months
(d) a strike at foamy soda s main plant forced production cutbacks that resulted in many stores not receiving their normal shipments during the summer months

(e) at least one of dr q s characterizations of dr. z s work fails to provide an adequate basis for sound criticism of that work.
16. k, a research scientist, was accused of having falsified laboratory data. although the original data in question have disappeared, data from k s more recent experiments have been examined and clearly none of them were falsified. therefore, the accusation should be dismissed.
which one of the following contains questionable reasoning that is most similar to that in the argument above?
(a) l, an accountant, was charged with having embezzled funds from a client. the charge should be ignored, however, because although the records that might reveal this embezzlement have been destroyed, records of l s current clients show clearly that there has never been any embezzlement from them.
(b) m, a factory supervisor, was accused of failing to enforce safety standards. this accusation should be discussed because although the identity of the accuser was not revealed, a survey of factory personnel revealed that some violations of the standards have occurred.
(c) n, a social scientist, was charged with plagiarism. the charge is without foundation because although strong similarities between n s book and the work of another scholar have been discovered, the other scholar s work was written after n s work was published.
(d) o, an auto mechanic has been accused of selling stolen auto parts the accusation seems to be justified since although no evidence links o directly to these sales, the pattern of distribution of the auto parts points to o as the source.
(e) p, a politician, has been accused of failing to protect the public interest. from at least some points of view, however, the accusation will undoubtedly be considered false, because there is clearly disagreement about where the public interest lies.
questions 17-18
the widespread staff reductions in a certain region s economy are said to be causing people who still have their jobs to cut back on new purchases as though they, too, had become economically distressed. clearly, however, actual spending by such people is undiminished, because there has been no unusual increase in the amount of money held by those people in savings accounts.
17. the argument in the passage proceeds by doing which one of the following?
(a) concluding that since an expected consequence of a supposed development did not take place
(b) concluding that since only one of the two predictable consequences of a certain kind of behavior is observed to occur this observed occurrence cannot, in the current situation, be a consequence of such behavior
(c) arguing that since people s economic behavior is guided by economic self- interest only misinformation or error will cause people to engage in economic behavior that harms them economically
(d) arguing that since two alternative developments exhaust all the plausible possibilities one of those developments occurred and the other did not
(e) concluding that since the evidence concerning a supposed change is ambiguous, it is most likely that no change is actually taking place.

20. when the pinecrest animal shelter, a charitable organization, was in danger of closing because it could not pay for important repairs, its directors appealed to the townspeople to donate money that would be earmarked to pay for those repairs. since more funds were ultimately donated than were used for the repairs the directors plan to donate the surplus funds to other animal shelters. but before doing so, the directors should obtain permission from those who made the donations
which one of the following priciples, if valid, most helps to justify the position advocated aboved above and yet places the least restriction on the allocation of funds by directors of charitable organizations?
(a) the directors of charitable organizations cannot allocate publicly solicited funds to any purposes for which the directors had not specifically carmarked the funds in advance
(b) people who solicit charitable donations from the public for a specific cause should spend the funds only on that cause or, if that becomes impossible, should dispose of the funds according to the express wishes of the donors.

21. the amount of electricity consumed in millville on any day in august is directly proportional to peak humidity on that day since the average peak humidity this august was three points higher than the average peak humidity last ausgust, it follows that more energy was consumed in millville this august than last august
which one of the following arguments has a pattern of reasoning most similar to the one in the argument above?
(a) the amount of art supplies used in any of the aesthetic institute s 25 classes is directly proportional to the number of students in that class. since in these classes the institute enrolled 20 percent more students overall last year than in the previous year mort art supplies were used in the institute s classes last year than in the provious year.
(b) the number of courses in painting offered by the aesthetic institute in any term is directly proportional to the number of students enrolled in the institute in that term. but the institute offers the same number of courses in sculpture each term. hence, the institute usually offers more courses in painting than in seulpture each term. hence, the institute usually offers more courses in painting than in sculpture.
(c) the number of new students enrolled at the aesthetic institute in any given year is directly proportional to the amount of advertising the institute has done in the previous year. hence, if the institute seeks to increase its student body it must increase the amount it spends on advertising
(d) the fees paid by a student at the aesthetic institute are didirectly proportional to the number of classes in which that student enrolls. since the number of students at the aesthetic institute is increasing, it follows that the institute is collecting a greater amount in fees paid by students than it used to
(e) the number of instructors employed by the aesthetic institute in any term is directly proportional to the number of classes offered in that term and also directly proportional to the number of students enrolled at the institute thus, the number of classes offered by the institute in any term is directly proportional to the number of students enrolled in that term.
22. letter to the editor: after baerton s factory closed, there was a sharp increase in the number of claims field for job-related injury compensation by the factory s former employees, hence there is reason to believe that most of those who filed for compensation after the factory closed were just out to gain benefits they did not deserve, and filed only to help them weather their job loss.
each of the following, if true, weakens the argument above except:
(a) workers cannot file for compensatio
n for many job-related injuries, such as hearings loss from factory noise, until they have left the job.
(b) in the years before the factory closed, the factory s managers dismissed several employees who had filed injury claims.
(c) most workers who receive an injury on the job file for compensation on the day they suffer the injury.
(d) workers who incur partial disabilities due to injuries on the job often donot file for compensation because they would have to stop working to receive compensation but cannot afford to live on that compensation alone.
(e) workers who are aware that they will soon be laid off from a job often become depressed, making them more prone to job-related injuries.
23. historians of north american architecture who have studied early nineteenth-century houses with wooden floors have observed that the boards used on the floors of bigger houses were generally much narrower than those used on the floors of smaller houses. these historians have argued that, since the people for whom the bigger houses were built were generally richer than the people for whom the smaller houses were probably once a status symbol, designed to proclaim the owner s wealth.
which one of the following, if true, most helps to strengthen the historians argument?
(a) more original floorboards have survived from big early nineteenth-century houses than from small early nineteenth-century houses than from small early nineteenth-century houses.
(b) in the early nineteenth century, a piece of narrow floorboard was not significantly less expensive than a piece of wide floorboard of the same length.
(c) in the early nineteenth century, smaller houses generally had fewer rooms than did bigger houses.
(d) some early nineteenth-century houses had wied floorboards near the walls of each room and narrower floorboards in the center, where the floors were usually carpeted.
(e) many of the biggest early nineteenth-century houses but very few small houses from that period had some floors that were made of materials that were considerably more expensive than wood, such as marble.
24. ethicist: a society is just when, and only when, first each person has an equal right to basic liberties, and second, inequalities in the distribution of income and wealth are not tolerated unles these inequalities are to everyone s advantage and are attached to jobs open to everyone.
which one of the following judgments most closely conforms to the principle described above?
(a) society s guarantees everyone equal right to basic liberties, while allowing inequalities in the distribution of income and wealth that are to the advantage of everyone. further, the jobs to which these inequalities are attached are open to most people, thus, society s is just.
(b) society s gives everyone an equal right to basic liberties, but at the expense of creating inequalities in the distribution of income and wealth. thus, society s is not just.
(c) society s allows inequalities in the distribution of income and wealth, although everyone benefits and these inequalities are attached to jobs that are open to everyone. thus, society s is just.
(d) society s distributes income and wealth to everyone equally, but at the expense of creating inequalities in the right to basic liberties. thus, society s is not just.
(e) society s gives everyone an equal right to basic liberties, and although there is an inequality in the distribution of income and wealth, the jobs, to which these inequalities are attached are open to all. thus, society s is just.
25. economist: in order to decied what to do about protecting the ozone layer, we must determine the monetary amount of the economic resources that we would willingly expend to protect it. such a determination amounts to a calculation of the monetary value of the ozone layer.
environmentalists argue that the ozone layer does not have a calculable monetary value. however, we would not willingly expend an amount equal to all of the world s economic resources to protect tha ozone layer so the ozone layer is demonstrably worth less than that amount. thus, the ozone layer has a calculable monetary value.
the reasoning in the economist s argument is flawed in that the argument
(a) uses evidence that the monetary value of a particular natural resource is less than a certain amount in order to establish that the monetary value of any natural resource is less than that amount
(b) presupposes that the ozone layer should not be protected and then argues to that claim as a conclusion
(c) takes advantage of an ambiguity in the term "value" to deflect the environmentalists charge
(d) gives no reason for thinking that merely establishing an upper limit on a certain monetary value would allow the calculation of that monetary value
(e) does not directly address t
he argument of the environmentalists.
26. columnist on the arts: my elected government representatives were within their rights to vote to support the arts with tax dollars. while funded by the government. however, some artists have produced works of art that are morally or aesthetically offensive to many taxpayers. nonetheless. my conclusion is that no taxpayers have been treated unjustly whose tax dollars are used to fund some particular work of art that they may find abominable.
which one of the following principles, if valid, most supports the columnist s argument?
(a) taxpayers should be allowed to decide whether a portion of their tax dollars is to be used to fund the arts.
(b) the funding of a particular activity is warranted if it is funded by elected representatives who legitimately fund that activity in general.
(c) elected representatives are within their rights to fund any activity that is supported by a majority of their constituents.
(d) those who resent taxation to subsidize offensive art should ovte against their incumbent government representatives.
(e) since taxpayers are free to leave their country if they disapprove of their representatives decisions they have no right to complain about arts funding.
