Reading Comprehension

Each of the reading comprehension questions is based on the content of a passage. After reading the passage, answer all questions pertaining to it on the basis of what is stated or implied in the passage. For each question, select the best answer of the choices given.

Line    According to economic signaling theory,
        consumers may perceive the frequency with
        which an unfamiliar brand is advertised as a cue
        that the brand is of high quality. The notion that
(5)     highly advertised brands are associated with
        high-quality products does have some empirical
        support. Marquardt and McGann found that
        heavily advertised products did indeed rank high
        on certain measures of product quality. Because
(10)    large advertising expenditures represent
        a significant investment on the part of a
        manufacturer, only companies that expect to
        recoup these costs in the long run, through
        consumers’ repeat purchases of the product,
(15)    can afford to spend such amounts.
          However, two studies by Kirmani have found
        that although consumers initially perceive expensive
        advertising as a signal of high brand quality,
        at some level of spending the manufacturer’s
(20)    advertising effort may be perceived as unreasonably
        high, implying low manufacturer confidence in
        product quality. If consumers perceive excessive
        advertising effort as a sign of a manufacturer’s
        desperation, the result may be less favorable
(25)    brand perceptions. In addition, a third study by
        Kirmani, of print advertisements, found that the
        use of color affected consumer perception of
        brand quality. Because consumers recognize that
        color advertisements are more expensive than
(30)    black and white, the point at which repetition of an
        advertisement is perceived as excessive comes
        sooner for a color advertisement than for a black-
        and-white advertisement.

Which of the following best describes the purpose of the sentence in lines 10–15?
1. (A) To show that economic signaling theory fails to explain a finding
2. (B) To introduce a distinction not accounted for by economic signaling theory
3. (C) To account for an exception to a generalization suggested by Marquardt and McGann
4. (D) To explain why Marquardt and McGann’s research was conducted
5. (E) To offer an explanation for an observation reported by Marquardt and McGann
The primary purpose of the passage is to
1. (A) present findings that contradict one explanation for the effects of a particular advertising practice
2. (B) argue that theoretical explanations about the effects of a particular advertising practice are of limited value without empirical evidence
3. (C) discuss how and why particular advertising practices may affect consumers’ perceptions
4. (D) contrast the research methods used in two different studies of a particular advertising practice
5. (E) explain why a finding about consumer responses to a particular advertising practice was unexpected
Kirmani’s research, as described in the passage, suggests which of the following regarding consumers’ expectations about the quality of advertised products?
1. (A) Those expectations are likely to be highest if a manufacturer runs both black-and-white and color advertisements for the same product.
2. (B) Those expectations can be shaped by the presence of color in an advertisement as well as by the frequency with which an advertisement appears.
3. (C) Those expectations are usually high for frequently advertised new brands but not for frequently advertised familiar brands.
4. (D) Those expectations are likely to be higher for products whose black-and-white advertisements are often repeated than for those whose color advertisements are less often repeated.
5. (E) Those expectations are less definitively shaped by the manufacturer’s advertisements than by information that consumers gather from other sources.
Kirmani’s third study, as described in the passage, suggests which of the following conclusions about a black-and-white advertisement?
1. (A) It can be repeated more frequently than a comparable color advertisement could before consumers begin to suspect low manufacturer confidence in the quality of the advertised product.
2. (B) It will have the greatest impact on consumers’ perceptions of the quality of the advertised product if it appears during periods when a color version of the same advertisement is also being used.
3. (C) It will attract more attention from readers of the print publication in which it appears if it is used only a few times.
4. (D) It may be perceived by some consumers as more expensive than a comparable color advertisement.
5. (E) It is likely to be perceived by consumers as a sign of higher manufacturer confidence in the quality of the advertised product than a comparable color advertisement would be.

The passage suggests that Kirmani would be most likely to agree with which of the following statements about consumers’ perceptions of the relationship between the frequency with which a product is advertised and the product’s quality?

(A) Consumers’ perceptions about the frequency with which an advertisement appears are their primary consideration when evaluating an advertisement’s claims about product quality.
(B) Because most consumers do not notice the frequency of advertisement, it has little impact on most consumers’ expectations regarding product quality.
(C) Consumers perceive frequency of advertisement as a signal about product quality only when the advertisement is for a product that is newly on the market.
(D) The frequency of advertisement is not always perceived by consumers to indicate that manufacturers are highly confident about their products’ quality.
(E) Consumers who try a new product that has been frequently advertised are likely to perceive the advertisement’s frequency as having been an accurate indicator of the product’s quality.

Line    The idea of the brain as an information
        processor—a machine manipulating blips of energy
        according to fathomable rules—has come to
        dominate neuroscience. However, one enemy of
(5)     the brain-as-computer metaphor is John R. Searle,
        a philosopher who argues that since computers
        simply follow algorithms, they cannot deal with
        important aspects of human thought such as
        meaning and content. Computers are syntactic,
(10)    rather than semantic, creatures. People, on the
        other hand, understand meaning because they have
        something Searle obscurely calls the causal powers
        of the brain.
          Yet how would a brain work if not by reducing
(15)    what it learns about the world to information—some
        kind of code that can be transmitted from neuron
        to neuron? What else could meaning and content
        be? If the code can be cracked, a computer should
        be able to simulate it, at least in principle. But
(20)    even if a computer could simulate the workings
        of the mind, Searle would claim that the machine
        would not really be thinking; it would just be acting
        as if it were. His argument proceeds thus: if a
        computer were used to simulate a stomach, with
(25)    the stomach’s churnings faithfully reproduced on a
        video screen, the machine would not be digesting
        real food. It would just be blindly manipulating the
        symbols that generate the visual display.
          Suppose, though, that a stomach were simulated
(30)    using plastic tubes, a motor to do the churning, a
        supply of digestive juices, and a timing mechanism.
        If food went in one end of the device, what came out
        the other end would surely be digested food. Brains,
        unlike stomachs, are information processors, and if
(35)    one information processor were made to simulate
        another information processor, it is hard to see
        how one and not the other could be said to think.
        Simulated thoughts and real thoughts are made of
        the same element: information. The representations
(40)    of the world that humans carry around in their heads
        are already simulations. To accept Searle’s argument,
        one would have to deny the most fundamental notion
        in psychology and neuroscience: that brains work
        by processing information.

The main purpose of the passage is to
1. (A) propose an experiment
2. (B) analyze a function
3. (C) refute an argument
4. (D) explain a contradiction
5. (E) simulate a process
Which of the following is most consistent with Searle’s reasoning as presented in the passage?
1. (A) Meaning and content cannot be reduced to algorithms.
2. (B) The process of digestion can be simulated mechanically, but not on a computer.
3. (C) Simulated thoughts and real thoughts are essentially similar because they are composed primarily of information.
4. (D) A computer can use “causal powers” similar to those of the human brain when processing information.
5. (E) Computer simulations of the world can achieve the complexity of the brain’s representations of the world.
The author of the passage would be most likely to agree with which of the following statements about the simulation of organ functions?
1. (A) An artificial device that achieves the functions of the stomach could be considered a valid model of the stomach.
2. (B) Computer simulations of the brain are best used to crack the brain’s codes of meaning and content.
3. (C) Computer simulations of the brain challenge ideas that are fundamental to psychology and neuroscience.
4. (D) Because the brain and the stomach both act as processors, they can best be simulated by mechanical devices.
5. (E) The computer’s limitations in simulating digestion suggest equal limitations in computer-simulated thinking.
It can be inferred that the author of the passage believes that Searle’s argument is flawed by its failure to
1. (A) distinguish between syntactic and semantic operations
2. (B) explain adequately how people, unlike computers, are able to understand meaning
3. (C) provide concrete examples illustrating its claims about thinking
4. (D) understand how computers use algorithms to process information
5. (E) decipher the code that is transmitted from neuron to neuron in the brain
From the passage, it can be inferred that the author would agree with Searle on which of the following points?
1. (A) Computers operate by following algorithms.
2. (B) The human brain can never fully understand its own functions.
3. (C) The comparison of the brain to a machine is overly simplistic.
4. (D) The most accurate models of physical processes are computer simulations.
5. (E) Human thought and computer-simulated thought involve similar processes of representation.

Which of the following most accurately represents Searle’s criticism of the brain-as-computer metaphor, as that criticism is described in the passage?

(A) The metaphor is not experimentally verifiable.
(B) The metaphor does not take into account the unique powers of the brain.
(C) The metaphor suggests that a brain’s functions can be simulated as easily as those of a stomach.
(D) The metaphor suggests that a computer can simulate the workings of the mind by using the codes of neural transmission.
(E) The metaphor is unhelpful because both the brain and the computer process information.


Line    Women’s grassroots activism and their vision
        of a new civic consciousness lay at the heart of
        social reform in the United States throughout the
        Progressive Era, the period between the depression
(5)     of 1893 and America’s entry into the Second
        World War. Though largely disenfranchised except
        for school elections, white middle-class women
        reformers won a variety of victories, notably in
        the improvement of working conditions, especially
(10)    for women and children. Ironically, though,
        child labor legislation pitted women of different
        classes against one another. To the reformers,
        child labor and industrial home work were equally
        inhumane practices that should be outlawed, but,
(15)    as a number of women historians have recently
        observed, working-class mothers did not always
        share this view. Given the precarious finances of
        working-class families and the necessity of pooling
        the wages of as many family members as possible,
(20)    working-class families viewed the passage and
        enforcement of stringent child labor statutes as a
        personal economic disaster and made strenuous
        efforts to circumvent child labor laws. Yet
        reformers rarely understood this resistance in terms
(25)    of the desperate economic situation of working-
        class families, interpreting it instead as evidence
        of poor parenting. This is not to dispute women
        reformers’ perception of child labor as a terribly
        exploitative practice, but their understanding of
(30)    child labor and their legislative solutions for ending
        it failed to take account of the economic needs of
        working-class families.

The primary purpose of the passage is to
1. (A) explain why women reformers of the Progressive Era failed to achieve their goals
2. (B) discuss the origins of child labor laws in the late nineteenth and early twentieth centuries
3. (C) compare the living conditions of working-class and middle-class women in the Progressive Era
4. (D) discuss an oversight on the part of women reformers of the Progressive Era
5. (E) revise a traditional view of the role played by women reformers in enacting Progressive Era reforms
The view mentioned in line 17 of the passage refers to which of the following?
1. (A) Some working-class mothers’ resistance to the enforcement of child labor laws
2. (B) Reformers’ belief that child labor and industrial home work should be abolished
3. (C) Reformers’ opinions about how working-class families raised their children
4. (D) Certain women historians’ observation that there was a lack of consensus between women of different classes on the issue of child labor and industrial home work
5. (E) Working-class families’ fears about the adverse consequences that child labor laws would have on their ability to earn an adequate living
The author of the passage mentions the observations of women historians (lines 15–17) most probably in order to
1. (A) provide support for an assertion made in the preceding sentence (lines 10–12)
2. (B) raise a question that is answered in the last sentence of the passage (lines 27–32)
3. (C) introduce an opinion that challenges a statement made in the first sentence of the passage
4. (D) offer an alternative view to the one attributed in the passage to working-class mothers
5. (E) point out a contradiction inherent in the traditional view of child labor reform as it is presented in the passage
The passage suggests that which of the following was a reason for the difference of opinion between working-class mothers and women reformers on the issue of child labor?
1. (A) Reformers’ belief that industrial home work was preferable to child labor outside the home
2. (B) Reformers’ belief that child labor laws should pertain to working conditions but not to pay
3. (C) Working-class mothers’ resentment at reformers’ attempts to interfere with their parenting
4. (D) Working-class mothers’ belief that child labor was an inhumane practice
5. (E) Working-class families’ need for every employable member of their families to earn money
The author of the passage asserts which of the following about women reformers who tried to abolish child labor?
1. (A) They alienated working-class mothers by attempting to enlist them in agitating for progressive causes.
2. (B) They underestimated the prevalence of child labor among the working classes.
3. (C) They were correct in their conviction that child labor was deplorable but shortsighted about the impact of child labor legislation on working-class families.
4. (D) They were aggressive in their attempts to enforce child labor legislation, but were unable to prevent working-class families from circumventing them.
5. (E) They were prevented by their nearly total disenfranchisement from making significant progress in child labor reform.
According to the passage, one of the most striking achievements of white middle-class women reformers during the Progressive Era was
1. (A) gaining the right to vote in school elections
2. (B) mobilizing working-class women in the fight against child labor
3. (C) uniting women of different classes in grassroots activism
4. (D) improving the economic conditions of working-class families
5. (E) improving women’s and children’s working conditions

Critical Reasoning

Each of the critical reasoning questions is based on a short argument, a set of statements, or a plan of action. For each question, select the best answer of the choices given.

Vasquez-Morrell Assurance specializes in insuring manufacturers. Whenever a policyholder makes a claim, a claims adjuster determines the amount that Vasquez-Morrell is obligated to pay. Vasquez-Morrell is cutting its staff of claims adjusters by 15 percent. To ensure that the company’s ability to handle claims promptly is affected as little as possible by the staff cuts, consultants recommend that Vasquez-Morrell lay off those adjusters who now take longest, on average, to complete work on claims assigned to them.

Which of the following, if true, most seriously calls into question the consultants’ criterion for selecting the staff to be laid off?
1. (A) If the time that Vasquez-Morrell takes to settle claims increases significantly, it could lose business to other insurers.
2. (B) Supervisors at Vasquez-Morrell tend to assign the most complex claims to the most capable adjusters.
3. (C) At Vasquez-Morrell, no insurance payments are made until a claims adjuster has reached a final determination on the claim.
4. (D) There are no positions at Vasquez-Morrell to which staff currently employed as claims adjusters could be reassigned.
5. (E) The premiums that Vasquez-Morrell currently charges are no higher than those charged for similar coverage by competitors.
Prolonged spells of hot, dry weather at the end of the grape-growing season typically reduce a vineyard’s yield, because the grapes stay relatively small. In years with such weather, wine producers can make only a relatively small quantity of wine from a given area of vineyards. Nonetheless, in regions where wine producers generally grow their own grapes, analysts typically expect a long, hot, dry spell late in the growing season to result in increased revenues for local wine producers.

Which of the following, if true, does most to justify the analysts’ expectation?
1. (A) The lower a vineyard’s yield, the less labor is required to harvest the grapes.
2. (B) Long, hot, dry spells at the beginning of the grape-growing season are rare, but they can have a devastating effect on a vineyard’s yield.
3. (C) Grapes grown for wine production are typically made into wine at or near the vineyard in which they were grown.
4. (D) When hot, dry spells are followed by heavy rains, the rains frequently destroy grape crops.
5. (E) Grapes that have matured in hot, dry weather make significantly better wine than ordinary grapes.
In the past, most children who went sledding in the winter snow in Verland used wooden sleds with runners and steering bars. Ten years ago, smooth plastic sleds became popular; they go faster than wooden sleds but are harder to steer and slow. The concern that plastic sleds are more dangerous is clearly borne out by the fact that the number of children injured while sledding was much higher last winter than it was 10 years ago.

Which of the following, if true in Verland, most seriously undermines the force of the evidence cited?
1. (A) A few children still use traditional wooden sleds.
2. (B) Very few children wear any kind of protective gear, such as helmets, while sledding.
3. (C) Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.
4. (D) Most sledding injuries occur when a sled collides with a tree, a rock, or another sled.
5. (E) Because the traditional wooden sleds can carry more than one rider, an accident involving a wooden sled can result in several children being injured.
Metal rings recently excavated from seventh-century settlements in the western part of Mexico were made using the same metallurgical techniques as those used by Ecuadorian artisans before and during that period. These techniques are sufficiently complex to make their independent development in both areas unlikely. Since the people of these two areas were in cultural contact, archaeologists hypothesize that the metallurgical techniques used to make the rings found in Mexico were learned by Mexican artisans from Ecuadorian counterparts.

Which of the following would it be most useful to establish in order to evaluate the archaeologists’ hypothesis?
1. (A) Whether metal objects were traded from Ecuador to western Mexico during the seventh century
2. (B) Whether travel between western Mexico and Ecuador in the seventh century would have been primarily by land or by sea
3. (C) Whether artisans from western Mexico could have learned complex metallurgical techniques from their Ecuadorian counterparts without actually leaving western Mexico
4. (D) Whether metal tools were used in the seventh-century settlements in western Mexico
5. (E) Whether any of the techniques used in the manufacture of the metal rings found in western Mexico are still practiced among artisans in Ecuador today
Following several years of declining advertising sales, the Greenville Times reorganized its advertising sales force. Before reorganization, the sales force was organized geographically, with some sales representatives concentrating on city-center businesses and others concentrating on different outlying regions. The reorganization attempted to increase the sales representatives’ knowledge of clients’ businesses by having each sales representative deal with only one type of industry or of retailing. After the reorganization, revenue from advertising sales increased.

In assessing whether the improvement in advertising sales can properly be attributed to the reorganization, it would be most helpful to find out which of the following?
1. (A) What proportion of the total revenue of the Greenville Times is generated by advertising sales?
2. (B) Has the circulation of the Greenville Times increased substantially in the last two years?
3. (C) Among all the types of industry and retailing that use the Greenville Times as an advertising vehicle, which type accounts for the largest proportion of the newspaper’s advertising sales?
4. (D) Do any clients of the sales representatives of the Greenville Times have a standing order with the Times for a fixed amount of advertising per month?
5. (E) Among the advertisers in the Greenville Times, are there more types of retail business or more types of industrial business?
Motorists in a certain country frequently complain that traffic congestion is much worse now than it was 20 years ago. No real measure of how much traffic congestion there was 20 years ago exists, but the motorists’ complaints are almost certainly unwarranted. The country’s highway capacity has tripled in the last twenty years, thanks to a vigorous highway construction program, whereas the number of automobiles registered in the country has increased by only 75 percent.

Which of the following, if true, most seriously weakens the argument?
1. (A) Most automobile travel is local, and the networks of roads and streets in the country’s settled areas have changed little over the last 20 years.
2. (B) Gasoline prices are high, and miles traveled per car per year have not changed much over the last 20 years.
3. (C) The country’s urban centers have well-developed public transit systems that carry most of the people who commute into those centers.
4. (D) The average age of automobiles registered in the country is lower now than it was 20 years ago.
5. (E) Radio stations have long been broadcasting regular traffic reports that inform motorists about traffic congestion.
The percentage of households with an annual income of more than $40,000 is higher in Merton County than in any other county. However, the percentage of households with an annual income of $60,000 or more is higher in Sommer County.

If the statements above are true, which of the following must also be true?
1. (A) The percentage of households with an annual income of $80,000 is higher in Sommer County than in Merton County.
2. (B) Merton County has the second highest percentage of households with an annual income of $60,000 or more.
3. (C) Some households in Merton County have an annual income between $40,000 and $60,000.
4. (D) The number of households with an annual income of more than $40,000 is greater in Merton County than in Sommer County.
5. (E) Average annual household income is higher in Sommer County than in Merton County.
Tiger beetles are such fast runners that they can capture virtually any nonflying insect. However, when running toward an insect, a tiger beetle will intermittently stop and then, a moment later, resume its attack. Perhaps the beetles cannot maintain their pace and must pause for a moment’s rest; but an alternative hypothesis is that while running, tiger beetles are unable to adequately process the resulting rapidly changing visual information and so quickly go blind and stop.

Which of the following, if discovered in experiments using artificially moved prey insects, would support one of the two hypotheses and undermine the other?
1. (A) When a prey insect is moved directly toward a beetle that has been chasing it, the beetle immediately stops and runs away without its usual intermittent stopping.
2. (B) In pursuing a swerving insect, a beetle alters its course while running and its pauses become more frequent as the chase progresses.
3. (C) In pursuing a moving insect, a beetle usually responds immediately to changes in the insect’s direction, and it pauses equally frequently whether the chase is up or down an incline.
4. (D) If, when a beetle pauses, it has not gained on the insect it is pursuing, the beetle generally ends its pursuit.
5. (E) The faster a beetle pursues an insect fleeing directly away from it, the more frequently the beetle stops.
Guillemots are birds of Arctic regions. They feed on fish that gather beneath thin sheets of floating ice, and they nest on nearby land. Guillemots need 80 consecutive snow-free days in a year to raise their chicks, so until average temperatures in the Arctic began to rise recently, the guillemots’ range was limited to the southernmost Arctic coast. Therefore, if the warming continues, the guillemots’ range will probably be enlarged by being extended northward along the coast.

Which of the following, if true, most seriously weakens the argument?
1. (A) Even if the warming trend continues, there will still be years in which guillemot chicks are killed by an unusually early snow.
2. (B) If the Arctic warming continues, guillemots’ current predators are likely to succeed in extending their own range farther north.
3. (C) Guillemots nest in coastal areas, where temperatures are generally higher than in inland areas.
4. (D) If the Arctic warming continues, much of the thin ice in the southern Arctic will disappear.
5. (E) The fish that guillemots eat are currently preyed on by a wider variety of predators in the southernmost Arctic regions than they are farther north.
Some batches of polio vaccine used around 1960 were contaminated with SV40, a virus that in monkeys causes various cancers. Some researchers now claim that this contamination caused some cases of a certain cancer in humans, mesothelioma. This claim is not undercut by the fact that a very careful survey made in the 1960s of people who had received the contaminated vaccine found no elevated incidence of any cancer, since ____________.
1. (A) most cases of mesothelioma are caused by exposure to asbestos
2. (B) in some countries, there was no contamination of the vaccine
3. (C) SV40 is widely used in laboratories to produce cancers in animals
4. (D) mesotheliomas take several decades to develop
5. (E) mesothelioma was somewhat less common in 1960 than it is now
Gortland has long been narrowly self-sufficient in both grain and meat. However, as per capita income in Gortland has risen toward the world average, per capita consumption of meat has also risen toward the world average, and it takes several pounds of grain to produce one pound of meat. Therefore, since per capita income continues to rise, whereas domestic grain production will not increase, Gortland will soon have to import either grain or meat or both.

Which of the following is an assumption on which the argument depends?
1. (A) The total acreage devoted to grain production in Gortland will soon decrease.
2. (B) Importing either grain or meat will not result in a significantly higher percentage of Gortlanders’ incomes being spent on food than is currently the case.
3. (C) The per capita consumption of meat in Gortland is increasing at roughly the same rate across all income levels.
4. (D) The per capita income of meat producers in Gortland is rising faster than the per capita income of grain producers.
5. (E) People in Gortland who increase their consumption of meat will not radically decrease their consumption of grain.
The Hazelton coal-processing plant is a major employer in the Hazelton area, but national environmental regulations will force it to close if it continues to use old, polluting processing methods. However, to update the plant to use newer, cleaner methods would be so expensive that the plant will close unless it receives the tax break it has requested. In order to prevent a major increase in local unemployment, the Hazelton government is considering granting the plant’s request.

Which of the following would be most important for the Hazelton government to determine before deciding whether to grant the plant’s request?
1. (A) Whether the company that owns the plant would open a new plant in another area if the present plant were closed
2. (B) Whether the plant would employ far fewer workers when updated than it does now
3. (C) Whether the level of pollutants presently being emitted by the plant is high enough to constitute a health hazard for local residents
4. (D) Whether the majority of the coal processed by the plant is sold outside the Hazelton area
5. (E) Whether the plant would be able to process more coal when updated than it does now
A physically active lifestyle has been shown to help increase longevity. In the Wistar region of Bellaria, the average age at death is considerably higher than in any other part of the country. Wistar is the only mountainous part of Bellaria. A mountainous terrain makes even such basic activities as walking relatively strenuous; it essentially imposes a physically active lifestyle on people. Clearly, this circumstance explains the long lives of people in Wistar.

Which of the following, if true, most seriously weakens the argument?
1. (A) In Bellaria all medical expenses are paid by the government, so that personal income does not affect the quality of health care a person receives.
2. (B) The Wistar region is one of Bellaria’s least populated regions.
3. (C) Many people who live in the Wistar region have moved there in middle age or upon retirement.
4. (D) The many opportunities for hiking, skiing, and other outdoor activities that Wistar’s mountains offer make it a favorite destination for vacationing Bellarians.
5. (E) Per capita spending on recreational activities is no higher in Wistar than it is in other regions of Bellaria.
Cheever College offers several online courses via remote computer connection, in addition to traditional classroom-based courses. A study of student performance at Cheever found that, overall, the average student grade for online courses matched that for classroom-based courses. In this calculation of the average grade, course withdrawals were weighted as equivalent to a course failure, and the rate of withdrawal was much lower for students enrolled in classroom-based courses than for students enrolled in online courses.

If the statements above are true, which of the following must also be true of Cheever College?
1. (A) Among students who did not withdraw, students enrolled in online courses got higher grades, on average, than students enrolled in classroom-based courses.
2. (B) The number of students enrolled per course at the start of the school term is much higher, on average, for the online courses than for the classroom-based courses.
3. (C) There are no students who take both an online and a classroom-based course in the same school term.
4. (D) Among Cheever College students with the best grades, a significant majority take online, rather than classroom-based, courses.
5. (E) Courses offered online tend to deal with subject matter that is less challenging than that of classroom-based courses.
For years the beautiful Renaissance buildings in Palitito have been damaged by exhaust from the many tour buses that come to the city. There has been little parking space, so most buses have idled at the curb during each stop on their tour, and idling produces as much exhaust as driving. The city has now provided parking that accommodates a third of the tour buses, so damage to Palitito’s buildings from the buses’ exhaust will diminish significantly.

Which of the following, if true, most strongly supports the argument?
1. (A) The exhaust from Palitito’s few automobiles is not a significant threat to Palitito’s buildings.
2. (B) Palitito’s Renaissance buildings are not threatened by pollution other than engine exhaust.
3. (C) Tour buses typically spend less than one-quarter of the time they are in Palitito transporting passengers from one site to another.
4. (D) More tourists come to Palitito by tour bus than by any other single means of transportation.
5. (E) Some of the tour buses that are unable to find parking drive around Palitito while their passengers are visiting a site.
During the 1980s and 1990s, the annual number of people who visited the Sordellian Mountains increased continually, and many new ski resorts were built. Over the same period, however, the number of visitors to ski resorts who were caught in avalanches decreased, even though there was no reduction in the annual number of avalanches in the Sordellian Mountains.

Which of the following, if true in the Sordellian Mountains during the 1980s and 1990s, most helps to explain the decrease?
1. (A) Avalanches were most likely to happen when a large new snowfall covered an older layer of snow.
2. (B) Avalanches destroyed at least some buildings in the Sordellian Mountains in every year.
3. (C) People planning new ski slopes and other resort facilities used increasingly accurate information about which locations are likely to be in the path of avalanches.
4. (D) The average length of stay for people visiting the Sordellian Mountains increased slightly.
5. (E) Construction of new ski resorts often led to the clearing of wooded areas that had helped to prevent avalanches.
A year ago, Dietz Foods launched a yearlong advertising campaign for its canned tuna. Last year Dietz sold 12 million cans of tuna compared to the 10 million sold during the previous year, an increase directly attributable to new customers brought in by the campaign. Profits from the additional sales, however, were substantially less than the cost of the advertising campaign. Clearly, therefore, the campaign did nothing to further Dietz’s economic interests.

Which of the following, if true, most seriously weakens the argument?
1. (A) Sales of canned tuna account for a relatively small percentage of Dietz Foods’ profits.
2. (B) Most of the people who bought Dietz’s canned tuna for the first time as a result of the campaign were already loyal customers of other Dietz products.
3. (C) A less expensive advertising campaign would have brought in significantly fewer new customers for Dietz’s canned tuna than did the campaign Dietz Foods launched last year.
4. (D) Dietz made money on sales of canned tuna last year.
5. (E) In each of the past five years, there was a steep, industry-wide decline in sales of canned tuna.

Problem Solving

The following discussion is intended to familiarize you with the most efficient and effective approaches to the kinds of problems common to problem solving questions. The particular questions in this chapter are generally representative of the kinds of quantitative questions you will encounter on the GMAT exam. Remember that it is the problem solving strategy that is important, not the specific details of a particular question.

Last month a certain music club offered a discount to preferred customers. After the first compact disc purchased, preferred customers paid $3.99 for each additional compact disc purchased. If a preferred customer purchased a total of 6 compact discs and paid $15.95 for the first compact disc, then the dollar amount that the customer paid for the 6 compact discs is equivalent to which of the following?
1. (A)
2. (B)
3. (C)
4. (D)
5. (E)
Arithmetic Operations on rational numbers
The cost of the 6 compact discs, with $15.95 for the first one and $3.99 for the other 5 discs, can be expressed as . It is clear from looking at the answer choices that some regrouping of the values is needed because none of the answer choices uses $3.99 in the calculation.
If $4.00 is used instead of $3.99, each one of the 5 additional compact discs is calculated at $0.01 too much, and the total cost is too high. There is an overage of $0.05 that must be subtracted from the $15.95, or thus . Therefore, the cost can be expressed as 5(4.00) + 15.90.
The correct answer is A.
The average (arithmetic mean) of the integers from 200 to 400, inclusive, is how much greater than the average of the integers from 50 to 100, inclusive?
1. (A) 150
2. (B) 175
3. (C) 200
4. (D) 225
5. (E) 300
Arithmetic Statistics
In the list of integers from 200 to 400 inclusive, the middle value is 300. For every integer above 300, there exists an integer below 300 that is the same distance away from 300; thus the average of the integers from 200 to 400, inclusive, will be kept at 300. In the same manner, the average of the integers from 50 to 100, inclusive, is 75.
The difference is .
The correct answer is D.
The sequence a₁, a₂, a₃,. . . ,a_n,. . . is such that for all . If and , what is the value of a₆?
1. (A) 12
2. (B) 16
3. (C) 20
4. (D) 24
5. (E) 28
Algebra Applied problems
According to this formula, it is necessary to know the two prior terms in the sequence to determine the value of a term; that is, it is necessary to know both and to find a_n. Therefore, to find a₆, the values of a₅ and a₄ must be determined. To find a₄, let , which makes and . Then, by substituting the given values into the formula

substitute known values

multiply both sides

subtract 4 from both sides

Then, letting , substitute the known values:

substitute known values

simplify

The correct answer is E.
Among a group of 2,500 people, 35 percent invest in municipal bonds, 18 percent invest in oil stocks, and 7 percent invest in both municipal bonds and oil stocks. If 1 person is to be randomly selected from the 2,500 people, what is the probability that the person selected will be one who invests in municipal bonds but NOT in oil stocks?
1. (A)
2. (B)
3. (C)
4. (D)
5. (E)
Arithmetic Probability
Since there are 2,500 people, 875 people invest in municipal bonds, and of those people invest in both municipal bonds and oil stocks. Therefore, there are people who invest in municipal bonds but not in oil stocks. Probability of an event

.
Probability of investing in municipal bonds but not in oil stocks .
The correct answer is B.
A closed cylindrical tank contains cubic feet of water and is filled to half its capacity. When the tank is placed upright on its circular base on level ground, the height of the water in the tank is 4 feet. When the tank is placed on its side on level ground, what is the height, in feet, of the surface of the water above the ground?
1. (A) 2
2. (B) 3
3. (C) 4
4. (D) 6
5. (E) 9
Geometry Volume
Since the cylinder is half full, it will be filled to half its height, whether it is upright or on its side. When the cylinder is on its side, half its height is equal to its radius.

Using the information about the volume of water in the upright cylinder, solve for this radius to determine the height of the water when the cylinder is on its side.

known volume of water is

substitute 4 for h; divide both sides by

solve for r

radius height of the water in the cylinder on its side

The correct answer is B.
A marketing firm determined that, of 200 households surveyed, 80 used neither Brand A nor Brand B soap, 60 used only Brand A soap, and for every household that used both brands of soap, 3 used only Brand B soap. How many of the 200 households surveyed used both brands of soap?
1. (A) 15
2. (B) 20
3. (C) 30
4. (D) 40
5. (E) 45
Arithmetic Operations on rational numbers
Since it is given that 80 households use neither Brand A nor Brand B, then must use Brand A, Brand B, or both. It is also given that 60 households use only Brand A and that three times as many households use Brand B exclusively as use both brands. If x is the number of households that use both Brand A and Brand B, then 3x use Brand B alone. A Venn diagram can be helpful for visualizing the logic of the given information for this item:

All the sections in the circles can be added up and set equal to 120, and then the equation can be solved for x:

combine like terms

subtract 60 from both sides

divide both sides by 4

The correct answer is A.
A certain club has 10 members, including Harry. One of the 10 members is to be chosen at random to be the president, one of the remaining 9 members is to be chosen at random to be the secretary, and one of the remaining 8 members is to be chosen at random to be the treasurer. What is the probability that Harry will be either the member chosen to be the secretary or the member chosen to be the treasurer?
1. (A)
2. (B)
3. (C)
4. (D)
5. (E)
Arithmetic Probability
Two probabilities must be calculated here: (1) the probability of Harry’s being chosen for secretary and (2) the probability of Harry’s being chosen for treasurer. For any probability, the probability of an event’s occurring .
1. (1)If Harry is to be secretary, he first CANNOT have been chosen for president, and then he must be chosen for secretary. The probability that he will be chosen for president is , so the probability of his NOT being chosen for president is . Then, the probability of his being chosen for secretary is . Once he is chosen, the probability that he will be selected for treasurer is 0, so the probability that he will NOT be selected for treasurer is . Thus, the probability that Harry will be chosen for secretary is .
2. (2)If Harry is to be treasurer, he needs to be NOT chosen for president, then NOT chosen for secretary, and then finally chosen for treasurer. The probability that he will NOT be chosen for president is again . The probability of his NOT being chosen for secretary is . The probability of his being chosen for treasurer is , so the probability that Harry will be chosen for treasurer is .
3. (3) So, finally, the probability of Harry’s being chosen as either secretary or treasurer is thus .
The correct answer is E.
If a certain toy store’s revenue in November was of its revenue in December and its revenue in January was of its revenue in November, then the store’s revenue in December was how many times the average (arithmetic mean) of its revenues in November and January?
1. (A)
2. (B)
3. (C)
4. (D) 2
5. (E) 4
Arithmetic Statistics
Let n be the store’s revenue in November, d be the store’s revenue in December, and j be the store’s revenue in January. The information from the problem can be expressed as and for n in the second equation gives . Then, the average of the revenues in November and January can be found by using these values in the formula

, as follows:

Solve for the store’s revenue in December by multiplying both sides of this equation by 4:

average

Thus, the store’s revenue in December was 4 times its average revenue in November and January.
The correct answer is E.
A researcher computed the mean, the median, and the standard deviation for a set of performance scores. If 5 were to be added to each score, which of these three statistics would change?
1. (A) The mean only
2. (B) The median only
3. (C) The standard deviation only
4. (D) The mean and the median
5. (E) The mean and the standard deviation
Arithmetic Statistics
If 5 were added to each score, the mean would go up by 5, as would the median. However, the spread of the values would remain the same, simply centered around a new value. So, the standard deviation would NOT change.
The correct answer is D.
