Тема/шкала: Critical reasoning
Reviewer: The book Art’s Decline argues that European painters today lack skills that were common among European painters of preceding centuries. In this the book must be right, since its analysis of 100 paintings, 50 old and 50 contemporary, demonstrates convincingly that none of the contemporary paintings are executed as skillfully as the older paintings.

Which of the following points to the most serious logical flaw in the reviewer’s argument?
?) The paintings chosen by the book’s author for analysis could be those that most support the book’s thesis.
?) The particular methods currently used by European painters could require less artistic skill than do methods used by painters in other parts of the world.
?) There could be criteria other than the technical skill of the artist by which to evaluate a painting.
?) The title of the book could cause readers to accept the book’s thesis even before they read the analysis of the paintings that supports it.
?) A reader who was not familiar with the language of art criticism might not be convinced by the book’s analysis of the 100 paintings.

Тема/шкала: Critical reasoning
A museum has been offered an undocumented statue, supposedly Greek and from the sixth century B.C. Possibly the statue is genuine but undocumented because it was recently unearthed or because it has been privately owned. However, an ancient surface usually has uneven weathering, whereas the surface of this statue has the uniform quality characteristically produced by a chemical bath used by forgers to imitate a weathered surface. Therefore, the statue is probably a forgery.

Which of the following, if true, most seriously weakens the argument?
?) The subject's pose and other aspects of the subject's treatment exhibit all the most common features of Greek statues of the sixth century B.C.
?) Museums can accept a recently unearthed statue only with valid export documentation from its country of origin.
?) The chemical bath that forgers use was at one time used by dealers and collectors to remove the splotchy surface appearance of genuinely ancient sculptures.
?) Museum officials believe that forgers have no technique that can convincingly simulate the patchy weathering characteristic of the surfaces of ancient sculptures.
?) An allegedly Roman sculpture with a uniform surface similar to that of the statue being offered to the museum was recently shown to be a forgery.

Тема/шкала: Critical reasoning
To prevent some conflicts of interest, Congress could prohibit high-level government officials from accepting positions as lobbyists for three years after such officials leave government service. One such official concluded, however, that such a prohibition would be unfortunate because it would prevent high-level government officials from earning a livelihood for three years.

The official’s conclusion logically depends on which of the following assumptions?
?) Laws should not restrict the behavior of former government officials.
?) Low-level government officials do not often become lobbyists when they leave government service.
?) High-level government officials who leave government service are currently permitted to act as lobbyists for only three years.
?) Lobbyists are typically people who have previously been high-level government officials.
?) High-level government officials who leave government service are capable of earning a livelihood only as lobbyists.

Тема/шкала: Critical reasoning
Manufacturers of mechanical pencils make most of their profit on pencil leads rather than on the pencils themselves. The Write Company, which cannot sell its leads as cheaply as other manufacturers can, plans to alter the design of its mechanical pencil so that it will accept only a newly designed Write Company lead, which will be sold at the same price as the Write Company's current lead.

Which of the following, if true, most strongly supports the Write Company's projection that its plan will lead to an increase in its sales of pencil leads?
?) A Write Company executive is studying ways to reduce the cost of manufacturing pencil leads.
?) A rival manufacturer recently announced similar plans to introduce a mechanical pencil that would accept only the leads produced by that manufacturer.
?) First-time buyers of mechanical pencils tend to buy the least expensive mechanical pencils available.
?) In extensive test marketing, mechanical-pencil users found the new Write Company pencil markedly superior to other mechanical pencils they had used.
?) Annual sales of mechanical pencils are expected to triple over the next five years.

Тема/шкала: Critical reasoning
Roland: The alarming fact is that 90 percent of the people in this country now report that they know someone who is unemployed.

Sharon: But a normal, moderate level of unemployment is 5 percent, with 1 out of 20 workers unemployed. So at any given time if a person knows approximately 50 workers, 1 or more will very likely be unemployed.

Sharon's argument is structured to lead to which of the following as a conclusion?
?) It is unlikely that the people whose statements Roland cites are giving accurate reports.
?) If at least 5% of workers are unemployed, the result of questioning a representative group of people cannot be the percentage Roland cites.
?) If an unemployment figure is given as a certain percent, the actual percentage of those without jobs is even higher.
?) The fact that 90% of the people know someone who is unemployed is not an indication that unemployment is abnormally high.
?) The current level of unemployment is not moderate.

Guitar strings often go “dead”—become less responsive and bright in tone—after a few weeks of intense use. A researcher whose son is a classical guitarist hypothesized that dirt and oil, rather than changes in the material properties of the string, were responsible.

Which of the following investigations is most likely to yield significant information that would help to evaluate the researcher's hypothesis?
?) Determining if a metal alloy is used to make the strings used by classical guitarists
?) Determining whether classical guitarists make their strings go dead faster than do folk guitarists
?) Determining whether a dead string and a new string produce different qualities of sound
?) Determining whether identical lengths of string, of the same gauge, go dead at different rates when strung on various brands of guitars
?) Determining whether smearing various substances on new guitar strings causes them to go dead

Тема/шкала: Critical reasoning
Many breakfast cereals are fortified with vitamin supplements. Some of these cereals provide 100 percent of the recommended daily requirement of vitamins. Nevertheless, a well-balanced breakfast, including a variety of foods, is a better source of those vitamins than are such fortified breakfast cereals alone.

Which of the following, if true, would most strongly support the position above?
?) Unprocessed cereals are naturally high in several of the vitamins that are usually added to fortified breakfast cereals.
?) In many foods, the natural combination of vitamins with other nutrients makes those vitamins more usable by the body than are vitamins added in vitamin supplements.
?) Cereals containing vitamin supplements are no harder to digest than similar cereals without added vitamins.
?) Foods often must be fortified with vitamin supplements because naturally occurring vitamins are removed during processing.
?) People who regularly eat cereals fortified with vitamin supplements sometimes neglect to eat the foods in which the vitamins occur naturally.

Increases in the level of high-density lipoprotein (HDL) in the human bloodstream lower bloodstream cholesterol levels by increasing the body’s capacity to rid itself of excess cholesterol. Levels of HDL in the bloodstream of some individuals are significantly increased by a program of regular exercise and weight reduction.

Which of the following can be correctly inferred from the statements above?
?) Only regular exercise is necessary to decrease cholesterol levels in the bloodstream of individuals of average weight.
?) Exercise and weight reduction are the most effective methods of lowering bloodstream cholesterol levels in humans.
?) Individuals who do not exercise regularly have a high risk of developing high levels of cholesterol in the bloodstream late in life.
?) Individuals who are underweight do not run any risk of developing high levels of cholesterol in the bloodstream.
?) A program of regular exercise and weight reduction lowers cholesterol levels in the bloodstream of some individuals.

Тема/шкала: Critical reasoning
According to the Tristate Transportation Authority, making certain improvements to the main commuter rail line would increase ridership dramatically. The authority plans to finance these improvements over the course of five years by raising automobile tolls on the two highway bridges along the route the rail line serves. Although the proposed improvements are indeed needed, the authority’s plan for securing the necessary funds should be rejected because it would unfairly force drivers to absorb the entire cost of something from which they receive no benefit.

Which of the following, if true, would cast the most doubt on the effectiveness of the authority’s plan to finance the proposed improvements by increasing bridge tolls?
?) When tolls were last increased on the two bridges in question, almost 20 percent of the regular commuter traffic switched to a slightly longer alternative route that has since been improved.
?) Whenever bridge tolls are increased, the authority must pay a private contractor to adjust the automated toll-collecting machines.
?) Before the authority increases tolls on any of the area bridges, it is required by law to hold public hearings at which objections to the proposed increase can be raised.
?) The chairman of the authority is a member of the Tristate Automobile Club that has registered strong opposition to the proposed toll increase.
?) Between the time a proposed toll increase is announced and the time the increase is actually put into effect, many commuters buy more tokens than usual to postpone the effects of the increase.

Тема/шкала: Critical reasoning
In Asia, where palm trees are non-native, the trees’ flowers have traditionally been pollinated by hand, which has kept palm fruit productivity unnaturally low. When weevils known to be efficient pollinators of palm flowers were introduced into Asia in 1980, palm fruit productivity increased—by up to 50 percent in some areas—but then decreased sharply in 1984.

Which of the following statements, if true, would best explain the 1984 decrease in productivity?
?) Prices for palm fruit fell between 1980 and 1984 following the rise in production and a concurrent fall in demand.
?) Rapid increases in productivity tend to deplete trees of nutrients needed for the development of the fruit-producing female flowers.
?) Prior to 1980 another species of insect pollinated the Asian palm trees, but not as efficiently as the species of weevil that was introduced in 1980.
?) Imported trees are often more productive than native trees because the imported ones have left behind their pests and diseases in their native lands.
?) weevil population in Asia remained at approximately the same level between 1980 and 1984.

Which of the following best completes the passage below?

People buy prestige when they buy a premium product. They want to be associated with something special. Mass-marketing techniques and price reduction strategies should not be used because __________.
?) continued sales depend directly on the maintenance of an aura of exclusivity
?) manufacturing a premium brand is not necessarily more costly than manufacturing a standard brand of the same product
?) affluent purchasers currently represent a shrinking portion of the population of all purchasers
?) purchasers of premium products are concerned with the quality as well as with the price of the products
?) expansion of the market niche to include a broader spectrum of consumers will increase profits
Вопрос id:1907842
Тема/шкала: Critical reasoning
Products sold under a brand name used to command premium prices because, in general, they were superior to nonbrand rival products. Technical expertise in product development has become so widespread, however, that special quality advantages are very hard to obtain these days and even harder to maintain. As a consequence, brand-name products generally neither offer higher quality nor sell at higher prices. Paradoxically, brand names are a bigger marketing advantage than ever.

Which of the following, if true, most helps to resolve the paradox outlined above?
?) Brand names are taken by consumers as a guarantee of getting a product as good as the best rival products.
?) In the days when special quality advantages were easier to obtain than they are now, it was also easier to get new brand names established.
?) Consumers recognize that the quality of products sold under invariant brand names can drift over time.
?) The advertising of a company's brand-name products is at times transferred to a new advertising agency, especially when sales are declining.
?) In many acquisitions of one corporation by another, the acquiring corporation is interested more in acquiring the right to use certain brand names than in acquiring existing production facilities.

Тема/шкала: Critical reasoning
Consumer advocate: It is generally true, at least in this state, that lawyers who advertise a specific service charge less for that service than lawyers who do not advertise. It is also true that each time restrictions on the advertising of legal services have been eliminated, the number of lawyers advertising their services has increased and legal costs to consumers have declined in consequence. However, eliminating the state requirement that legal advertisements must specify fees for specific services would almost certainly increase rather than further reduce consumers’ legal costs. Lawyers would no longer have an incentive to lower their fees when they begin advertising and if no longer required to specify fee arrangements, many lawyers who now advertise would increase their fees.

In the consumer advocate’s argument, the two portions in boldface play which of the following roles?
?) The first is a pattern of cause and effect that the consumer advocate argues will be repeated in the case at issue; the second acknowledges a circumstance in which that pattern would not hold.
?) The first is a pattern of cause and effect that the consumer advocate predicts will not hold in the case at issue; the second offers a consideration in support of that prediction.
?) The first acknowledges a consideration that weighs against the main position that the consumer advocate defends; the second is that position.
?) The first is a generalization that the consumer advocate accepts as true; the second is presented as a consequence that follows from the truth of that generalization.
?) The first is evidence that the consumer advocate offers in support of a certain prediction; the second is that prediction.

Тема/шкала: Critical reasoning
Correctly measuring the productivity of service workers is complex. Consider, for example, postal workers: they are often said to be more productive if more letters are delivered per postal worker. But is this really true? What if more letters are lost or delayed per worker at the same time that more are delivered?

The objection implied above to the productivity measure described is based on doubts about the truth of which of the following statements?
?) Postal workers are representative of service workers in general.
?) The quality of services rendered can appropriately be ignored in computing productivity.
?) Productivity should be ascribed to categories of workers, not to individuals.
?) The number of letters delivered is relevant to measuring the productivity of postal workers.
?) The delivery of letters is the primary activity of the postal service.

Тема/шкала: Critical reasoning
The technological conservatism of bicycle manufacturers is a reflection of the kinds of demand they are trying to meet. The only cyclists seriously interested in innovation and willing to pay for it are bicycle racers. Therefore, innovation in bicycle technology is limited by what authorities will accept as standard for purposes of competition in bicycle races.

Which of the following is an assumption made in drawing the conclusion above?
?) The market for cheap, traditional bicycles cannot expand unless the market for high-performance competition bicycles expands.
?) Bicycle racers do not generate a strong demand for innovations that fall outside what is officially recognized as standard for purposes of competition.
?) High-performance bicycles are likely to be improved more as a result of technological innovations developed in small workshops than as a result of technological innovations developed in major manufacturing concerns.
?) The technological conservatism of bicycle manufacturers results primarily from their desire to manufacture a product that can be sold without being altered to suit different national markets.
?) The authorities who set standards for high-performance bicycle racing do not keep informed about innovative bicycle design.
