[ "referring to the large numbers of scholarly adherents of a certain view to support the claim that the view is correct", "establishing a general principle and using the principle to justify a conclusion about a particular category of cases", "citing both a lack of evidence supporting a particular explanation and further evidence that suggests an alternative explanation", "providing reasons to suspect the reliability of any conclusions based on evidence concerning the distant past" ]
Many scholars believe that official medieval persecutions of various minority groups were undertaken very reluctantly by medieval authorities and only in order to soothe popular unrest caused by underlying popular hostility to the groups in question. This belief is highly questionable. For one thing, there are few indications of any profound underlying popular hostility toward persecuted groups in cases where persecutions were particularly violent and sustained. For another, the most serious and widespread persecutions carried out by medieval authorities seem to have had as targets exactly those groups that most effectively disputed these authorities' right to govern.

[ "Some patients may have allergic reactions to certain medicines that have been tolerated by other patients.", "Any pain relief or other benefits of many herbs have been proven to derive entirely from patients' belief in the remedy, rather than from its biochemical properties.", "The vast majority of purveyors of alternative medicines are driven as much by the profit motive as by a regard for their patients' health.", "Many practitioners and patients neglect more effective conventional medicines in favor of herbal remedies." ]
Doctor: While a few alternative medicines have dangerous side effects, some, such as many herbs, have been proven safe to consume. Thus, though there is little firm evidence of medicinal effect, advocates of these herbs as remedies for serious illnesses should always be allowed to prescribe them, since their patients will not be harmed, and might be helped, by the use of these products.

Philosopher: The eighteenth-century thesis that motion is absolute asserts that the change in an object' s position over time could be measured without reference to the position of any other object. A well-respected physicist, however, claims that this thesis is incoherent. Since a thesis that is incoherent cannot be accepted as a description of reality, motion cannot be absolute.

[ "In recent years, employers have been requiring college degrees for workers in jobs that were previously performed successfully by Kravonians who did not have college degrees.", "Kravonians with more than one college degree earn little more, on average, than do Kravonians with only one college degree.", "The average number of years Kravonian college students remain enrolled before completing a degree has been increasing over the past several years.", "For many years, employers in Kravonia have had difficulty finding enough college graduates to fill the high-paying jobs that were available." ]
In Kravonia, the average salary for jobs requiring a college degree has always been higher than the average salary for jobs that do not require a degree. Over the last few years, the number of Kravonians enrolled in college has been growing steadily. Ttherefore, the number of Kravonians entering the job market who have at least the qualification of a college degree will eventually be significantly higher than it has been over the last few years.

Which of the following, if true, most seriously weakens the argument?
[ "The government office should not issue more than an average of 5 citations a year to drug companies for serious violations of drug-promotion laws.", "Before 1971 the government office issued more than 60 citations a year to drug companies for serious violations of drug-promotion laws.", "A change in enforcement of drug-promotion laws did not apply to minor violations.", "The decrease in the number of citations was not caused by a decrease in drug companies' violations of drug-promotion laws." ]
Between 1971 and 1975, the government office that monitors drug companies issued an average of 60 citations a year for serious violations of drug-promotion laws. Between 1976 and 1980, the annual average for issuance of suchs citations was only 5. This decrease indicates that the government office was, on average, considerably more lax in enforcing drug-promotion laws between 1976 and 1980 than it was between 1971 and 1975.

Lydia: Each year, thousands of seabirds are injured when they become entangled in equipment owned by fishing companies. Ttherefore, the fishing companies should assume responsibility for funding veterinary treatment for the injured birds. Jonathan: Your feelings for the birds are admirable.

So either manufacturers are efficient or they should be fined.", "If you go for a walk, when you are finished either you will feel relaxed or you will not. If you feel relaxed, then your muscles will likely not be sore the next day, though your muscles will more likely become conditioned faster if they do feel sore. Ttherefore, either your muscles will feel sore, or they will become better conditioned.", "If you use a computer, its messages are either easily readable or not.

A smoker trying to quit is more likely to succeed if his or her doctor greatly exaggerates the dangers of smoking. Similar strategies can be used to break other habits. But since such strategies involve deception, individuals cannot easily adopt them unless a doctor or some other third party provides the warning.

An undergraduate degree is necessary for appointment to the executive board. Further, no one with a felony conviction can be appointed to the board. Thus, Manu, an accountant with both a bachelor' s and a master' s degree, cannot be accepted for the position of Executive Administrator, since he has a felony conviction.

Given that employees of the XYZ Company could, in theory, do their work at home, the company developed a radical plan to increase efficiency: eliminate office-space expenditures by having employees work at home. To evaluate this plan, XYZ' s managers asked volunteers from the company' s staff to try the arrangement for six months. There were several volunteers; significantly, their productivity during this period was as high as or higher than before.

[ "Teachers who teach university-level mathematics to pre-university students should be aware that students are likely to learn effectively only when the application of mathematics to concrete problems is shown.", "Cognitive tasks that require exceptional effort tend to undermine the motivation of those who attempt them.", "Only those who, without losing motivation, can meet the cognitive challenges that new intellectual work involves should be introduced to it.", "Only those parts of university-level mathematics that are the most concrete should be taught to pre-university students." ]
Mathematics teacher: Teaching students calculus before they attend university may significantly benefit them. Yet if students are taught calculus before they are ready for the level of abstraction involved, they may abandon the study of mathematics altogether. So if we are going to teach pre-university students calculus, we must make sure they can handle the level of abstraction involved.

First-time computer buyers buying PXC home computers typically buy models that cost much less and have a smaller profit margin per computer than do PXC computers bought by people replacing their computers with more powerful models. Last year PXC' s profits from computer sales were substantially higher than the previous year, although about the same number of PXC computers were sold and the prices and profit margins for each computer model that PXC sells remained unchanged.

[ "Inertia in the flow of water pumped by an electrically powered pump is caused by inductance in the pump's circuits.", "The rate at which electrical current flows is affected by inductance.", "The flow of electrical current in a circuit requires inertia.", "Electrical engineers try to minimize the effects of inductance in electrical circuits." ]
Inertia affects the flow of water pumped through a closed system of pipes. When the pump is first switched on, the water, which has mass, takes time to reach full speed. When the pump is switched off, inertia causes the decrease in the water flow to be gradual. The effects of inductance in electrical circuits are similar to the effects of inertia in water pipes.

Pulford: Scientists who study the remains of ancient historical figures to learn about their health history need to first ask themselves if their investigation is a legitimate scientific inquiry or is motivated by mere curiosity.

Political strategist: Clearly, attacking an opposing candidate on philosophical grounds is generally more effective than attacking the details of the opponent' s policy proposals. A philosophical attack links an opponent' s policy proposals to an overarching ideological scheme, thereby telling a story and providing context. This makes the attack emotionally compelling.

There is a widespread belief that people can predict impending earthquakes from unusual animal behavior. Skeptics claim that this belief is based on selective coincidence: people whose dogs behaved oddly just before an earthquake will be especially likely to remember that fact. At any given time, the skeptics say, some of the world' s dogs will be behaving oddly.

Vandenburg: This art museum is not adhering to its purpose. Its founders intended it to devote as much attention to contemporary art as to the art of earlier periods, but its collection of contemporary art is far smaller than its other collections. Simpson: The relatively small size of the museum' s contemporary art collection is appropriate. It' s an art museum, not an ethnographic museum designed to collect every style of every period. Its contemporary art collection is small because its curators believe that there is little high-quality contemporary art.

Herbalist: Many herbal medicines work best when they have a chance to influence the body gently over several months. However, many of these herbal medicines have toxic side effects when taken daily for such long periods. Ttherefore, at least some people who use herbal medicines daily should occasionally skip their usual dose for a day or two, to give the body a chance to recuperate.

The Canadian elk has traditionally been limited in its geographic range by the presence of elderberries, its primary source of food, which only grow up until a certain point in the tundra. A recent rise in temperatures, however, has seen a spread in the growth of elderberries northwards into the tundra. Ttherefore, the overall range of the Canadian elk can be expected to increase.

Literature professor: Critics charge that the work of C. F. Providence' s best-known follower, S. N. Sauk, lacks aesthetic merit because it employs Providence' s own uniquely potent system of symbolic motifs in the service of a political ideal that Providence -- and, significantly, some of these critics as well -- would reject. Granting that Sauk is more imitator than innovator, and that he maintained political views very different from those Providence maintained, it has yet to be shown that these facts make his writings any less subtly or powerfully crafted than those of his more esteemed mentor. So the critics' argument should be rejected.

According to the theory of continental drift, in prehistoric times, many of today' s separate continents were part of a single huge landmass.

Scientist: In our study, chemical R did not cause cancer in laboratory rats. But we cannot conclude from this that chemical R is safe for humans.

To decrease the number of crimes in city Y, the city' s Police Commissioner proposed taking some police officers from low-crime districts of the city and moving them to high-crime districts of the city.

Corporate responsibility is just as important as individual responsibility, especially when it has so large an effect on the world.", "The argument fails to consider altruistic millennial behavior outside of the corporate environment.

Over 90 percent of the human brain currently serves no purpose, as is evident from the fact that many people with significant brain damage show no discernible adverse effects.

All potatoes naturally contain solanine, which is poisonous in large quantities. Domesticated potatoes contain only very small amounts of solanine, but many wild potatoes contain poisonous levels of solanine. Since most of the solanine in potatoes is concentrated in the skin, however, peeling wild potatoes makes them at least as safe to eat as unpeeled domesticated potatoes of the same size.

Director of personnel: Ms. Tours has formally requested a salary adjustment on the grounds that she was denied merit raises to which she was entitled. Since such grounds provide a possible basis for adjustments, an official response is required. Ms. Tours presents compelling evidence that her job performance has been both excellent in itself and markedly superior to that of others in her department who were awarded merit raises. Her complaint that she was treated unfairly thus appears justified. Nevertheless, her request should be denied. To raise Ms. Tours' s salary because of her complaint would jeopardize the integrity of the firm' s merit-based reward system by sending the message that employees can get their salaries raised if they just complain enough.

Lightbox, Inc. , owns almost all of the movie theaters in Washington County and has announced plans to double the number of movie screens it has in the county within five years. Yet attendance at Lightbox' s theaters is only just large enough for profitability now and the county' s population is not expected to increase over the next ten years.

Taxi driver: My passengers complained when, on a hot day, I turned off my cab' s air conditioner while driving up a steep hill.

Journalists sometimes use historical photographs to illustrate articles about current events. But this recycling of old photographs overstates the similarities between past and present, and thereby denies the individual significance of those current events. Hence, the use of historical photographs in this manner by journalists distorts public understanding of the present by presenting current events as mere repetitions of historical incidents.

[ "Children who catch one strain of the flu virus and then recover are likely to develop immunity to at least some strains with which they have not yet come in contact.", "Children are particularly unconcerned with hygiene and ttherefore are the group most responsible for spreading the flu virus to others.", "The vaccinations received last year will confer no immunity to this year's flu virus.", "Children are no more likely than adults to have immunity to a particular flu virus if they have never lived through a previous epidemic of the same virus." ]
Conventional wisdom suggests vaccinating elderly people first in flu season, because they are at greatest risk of dying if they contract the virus. This year's flu virus poses particular risk to elderly people and almost none at all to younger people, particularly children. Nevertheless, health professionals are recommending vaccinating children first against the virus rather than elderly people.

[ "The current regulations are designed to prevent children from using nicotine.", "The recent studies are not conclusive.", "The additives in electronic cigarettes have not been tested as thoroughly as those in traditional cigarettes.", "More smokers die from heart disease than cancer." ]
Electronic cigarettes should not be subject to the same regulation as other products that contain nicotine. Recent studies indicate that electronic cigarettes help people quit smoking by providing nicotine without the harmful tar and additive chemicals. Although electronic cigarettes also contain their own additives, they are much less harmful in the short-term than traditional cigarettes. People who smoke electronic cigarettes are ten times less likely to die from cancer than smokers of traditional cigarettes.

Art history professor: Costa criticizes my theories about the distinction between baroque and neoclassical Austrian painting. He argues that since there are no features possessed by all and only the works from a given historical period, assigning works of art to period styles is intellectually bankrupt . His reasoning can be discounted, however, since his own current theories on the transition from classical to romantic French opera also presuppose such an assignment.

Farm animals have certain behavioral tendencies that result from the evolutionary history of these species. By imposing on these animals a type of organization that conflicts with their behavioral tendencies, current farm-management practices cause the animals more pain and distress than do practices that more closely conform to the animals' behavioral tendencies. Because the animals tend to resist this type of organization, current practices can also be less efficient than those other farm-management practices.

People who have doctorates in the liberal arts are interested in improving their intellects.

Forest fragmentation occurs when development severs a continuous area of forest, breaking it down into small patches. Some animals, such as white-footed mice, thrive in conditions of forest fragmentation, reaching their highest population densities in small forest patches.

All social systems are based upon a division of economic roles. The values of a social system are embodied in the prestige accorded persons who fill various economic roles.

A certain auto repair shop services a particular make of car in the downtown region of a particular city. Three years ago, 4% of all repairs at this shop were not successful --- the mechanics were not able to restore the car to a drivable state. This year, only 2% of all repairs were not successful.

Sociologist: Many rural residents claim to only approve of modest lifestyles; yet, many of these same rural residents often buy magazines focused on the lives of celebrities.

A neurobiologist performed autopsies on male cats who died from disease X, a disease affecting no more than . 05 percent of male cats, and found that these male cats had interstitial nuclei that were as large as those generally found in female cats.

In jurisdictions where use of headlights is optional when visibility is good, drivers who use headlights at all times are less likely to be involved in a collision than are drivers who use headlights only when visibility is poor.

To protect certain fledgling industries, the government of country Z banned imports of the types of products those industries were starting to make.

In the nation of Partoria, large trucks currently have a much higher rate of traffic accidents per mile driven than other vehicles do. However, the very largest trucks-those with three trailers-had less than a third of the accident rate of single- and double-trailer trucks.

Advertisement: Clark brand-name parts are made for cars manufactured in this country. They satisfy all of our government automotive tests -- the toughest such tests in the world. With foreign-made parts, you never know which might be reliable and which are cheap look-alikes that are poorly constructed and liable to cost you hundreds of dollars in repairs. Ttherefore, be smart and insist on brand-name parts by Clark for your car.

In 1995, ecologists started to reintroduce the wolf into Yellowstone Park, where the wolf had been eliminated intentionally half a century earlier. Rangers expected a rise in the number of wolf would place limits on the elk population and on the populations of many mid-size mammals. One unexpected consequence was a dramatic rise in the population of foxes, which in turn helped to control many rodent populations.

[ "On other rivers in the region, the construction of dams with fish passes has led to only small decreases in the number of fish migrating upstream.", "During spawning season, the dam releases sufficient water for migratory fish below the dam to swim upstream.", "Populations of migratory fish in the Chiff River have been declining slightly over the last 20 years.", "The construction of the dam stirred up potentially toxic river sediments that were carried downstream." ]
To prevent a newly built dam on the Chiff River from blocking the route of fish migrating to breeding grounds upstream, the dam includes a fish pass, a mechanism designed to allow fish through the dam. Before the construction of the dam and fish pass, several thousand fish a day swam upriver during spawning season. But in the first season after the project' s completion, only 300 per day made the journey. Clearly, the fish pass is defective.

[ "fails to establish that the revolutionary party caused no suffering", "provides no evidence that the revolutionary party's goals were not overambitious", "fails to establish that any of the revolutionary party's critics underestimated the party's power", "gives mutually inconsistent responses to the two criticisms" ]
Historian: The revolutionary party has been accused of having many overambitious goals and of having caused great suffering. However, most of the party' s goals were quickly achieved and the party did not have enough power to cause the suffering the critics claim it caused. So it is clear that the party was not overambitious and caused no suffering.

Researcher: It is commonly believed that species belonging to the same biological order, such as rodents, descended from a single common ancestor. However, I compared the genetic pattern in 3 rodent species -- guinea pigs, rats, and mice -- as well as in 13 nonrodent mammals, and found that while rats and mice are genetically quite similar, the genetic differences between guinea pigs and mice are as great as those between mice and some nonrodent species. Thus, despite their similar physical form, guinea pigs stem from a separate ancestor.

[ "The domestic textile industry faces significant competition in many of its export markets.", "Reducing taxes on textile imports would financially benefit some consumers in the domestic economy but would not benefit the domestic textile industry.", "The added competition produced by any reduction of taxes on imports would significantly harm the domestic textile industry.", "The domestic textile industry and consumers in the domestic economy would benefit less from reductions in taxes on textile imports than they would from other measures." ]
Principle: A government should reduce taxes on imports if doing so would financially benefit many consumers in its domestic economy. There is a notable exception, however: it should never reduce import taxes if one or more of its domestic industries would be significantly harmed by the added competition. Conclusion: The government should not reduce taxes on textile imports.

Guideline: It is improper for public officials to influence the award of contracts or to perform other acts related to their office in a way that benefits themselves. Even the appearance of such impropriety should be avoided. Application: Greenville' s mayor acted improperly in urging the award of the city' s street maintenance contract to a company owned and operated by one of the mayor' s relatives, whose business would have been in serious financial trouble had it not been awarded the contract.

Police statistics have shown that automobile antitheft devices reduce the risk of car theft, but a statistical study of automobile theft by the automobile insurance industry claims that cars equipped with antitheft devices are, paradoxically, more likely to be stolen than cars that are not so equipped.

Editorial: The town would not need to spend as much as it does on removing trash if all town residents sorted their household garbage. However, while telling residents that they must sort their garbage would get some of them to do so, many would resent the order and refuse to comply. The current voluntary system, then, is to be preferred, because it costs about as much as a nonvoluntary system would and it does not engender nearly as much resentment.

When old-growth forests are cleared of tall trees, more sunlight reaches the forest floor. This results in a sharp increase in the population of leafy shrubs on which the mule deer depend for food. Yet mule deer herds that inhabit cleared forests are less well-nourished than are herds living in old-growth forests.

Though ice cream is an excellent source of calcium, dairy farmers report that during the past ten years there has been a sharp decline in ice cream sales. And during the same period, sales of cheddar cheese have nearly doubled. Ttherefore, more and more people must be choosing to increase their intake of calcium by eating cheddar cheese rather than ice cream.

[ "All of the patients in the study listened to the same tape before surgery as they listened to after surgery.", "Both anesthesia and painkillers tend to reduce stress.", "The psychological effects of music are not changed by anesthesia or painkillers.", "Listening to music reduces stress." ]
Reducing stress lessens a person' s sensitivity to pain. This is the conclusion reached by researchers who played extended audiotapes to patients before they underwent surgery and afterward while they were recovering. One tape consisted of conversation; the other consisted of music. Those who listened only to the latter tape required less anesthesia during surgery and fewer painkillers afterward than those who listened only to the former tape.

Biologists studying plant life in the prehistoric rainforest by utilizing samples of ancient ice and fossilized evidence of biological processes found that most of the plants removed an astonishingly small amount of carbon dioxide from the atmosphere. One biologist found that a certain tree currently found in the rainforest absorbs carbon dioxide from the atmosphere at a greater rate than any tree on the planet. The biologist hypothesized that the prevalence of this tree in the prehistoric rainforest accounts for the other plants' failure to remove larger amounts of carbon dioxide from the atmosphere.

TrueSave is a mail-order company that ships electronic products from its warehouses to customers worldwide. The company' s shipping manager is proposing that customer orders be packed with newer, more expensive packing materials that virtually eliminate damage during shipping. The manager argues that overall costs would essentially remain unaffected, since the extra cost of the new packing materials roughly equals the current cost of replacing products returned by customers because they arrived in damaged condition.

Fraenger' s assertion that the artist Hieronymus Bosch belonged to the Brethren of the Free Spirit, a nonmainstream religious group, is unlikely to be correct.

However, there is evidence that Bosch was a member of a mainstream church, and no evidence that he was a member of the Brethren.
