GRE GRE General Test Questions and Answers
Because they require abstraction and generalization, many theories end up_________practical relevance as they tail to capture the richness and complexity of phenomena encountered in real settings.
The poet Paul Laurence Dunbar (1872-1906) was the premier Black writer of poetry that used the dialect of rural African Americans of the southern United States. Although Dunbar ' s works were both popular with readers and acclaimed by literary critics during his lifetime, after the First World War a radical shift occurred, at least in critical opinion of his poetry, and twentieth-century critical evaluation of his work has been generally negative. Some critics attacked his work on social grounds for failing to challenge plantation stereotypes of African Americans. Other critics, such as the poet James Weldon Johnson, argued from aesthetic grounds that dialect poetry in general was too limited as an artistic medium, and capable of producing only two effects: pathos and humor. The negative critical trend only began to reverse itself in the 1970s, when scholars began to emphasize the importance of mythic, psychological, and historical dimensions of Dunbar ' s works, focusing on the interior and exterior realities of African American life after the Civil War.
Which of the following can be inferred from the passage concerning scholars ' use of mythic, psychological, and historical considerations in evaluating Dunbar ' s works?
Sensationalism—the purveyance of emotionally charged content. focused mainly on violent crime, to a broad public—has often been decried, but the full history of the phenomenon has yet to be written. Scholars have tended to dismiss sensationalism as unworthy of serious study, based on two pervasive though somewhat incompatible assumptions: first, that sensationalism is essentially a commercial product, built on the exploitation of modern mass media, and second, that it appeals almost entirely to a simple, basic emotion and thus has tittle history apart from the changing technological means of spreading it. An exploration of sensationalism ' s early history, however, challenges both assumptions and suggests that they have tended to obscure the complexity and historicity of the genre.
According to the passage, scholars have not given sensationalism serious consideration because they believe sensationalism

representing differing concerns or tactics, the food movement has been (iii)_________from its beginning.
One difficulty in convincing early scientists that craters fanned as a result of impacts from space is that most craters are circular. Impacts could come in at any angle, and experiments firing projectiles in the laboratory show that low-angle impacts lead to elliptical craters, not circular ones. Furthermore, while there was rarely evidence of any impacting object, there was often silicate melt around, suggesting that craters were caused by volcanic processes. The breakthrough in understanding crater origin was the recognition that the shock caused by the impacting object—not the object itself—creates a circular crater some twenty Times larger than the diameter of the impactor. The impact also generates enough heat to largely vaporize the impactor and melt the native rock.
What can be inferred from the passage about the silicate melt found around craters?
The geographer held a (i)________view of the succession of theoretical trends (environmental determinism, spatial determinism, and various types of critical theory) in her field, maintaining that theory can (n)________what is transpiring in a complex environment by focusing excessively on the favored schemes and variables of the moment.
Harriet Monroe, who founded Poetry: A Magazine of Verse in 1912. argued that the more heterogeneous and sprawling the modem world became, the more poetry needed " an entrenched place, a voice of power. " Hut this goal could only be realized if poets were valued in ways that encouraged them to participate in the world and made writing verse economically viable. Monroe argued that poets needed sites of institutional opportunity like those that had been developed for visual artists, architects, and musicians. She believed that the hand-wringing anticapitalism dominating genteel literary culture—particularly the idea that poetry ought to be removed from " sordid " pecuniary considerations—brought no economic and only illusory aesthetic benefits, instead severing poets from meaningful participation in the modern world.
The passage suggests that Monroe believed that finding " an entrenched place, a voice of power " for poetry would rely on which of the following?
Scholars generally estimate subscribers to Freedom z Journal (1827-1829), the United States " first African American newspaper, at around 800. based on subscriptions to The Rights of AIL an African American newspaper founded in 1829 as a successor to Freedom s Journal by a former editor of that newspaper But Gross argues that many more than 800 readers probably subscribed to Freedom X Journal because many of its subscribers, dissatisfied with the direction ultimately taken by the paper, refused to subscribe to The Rights of All. In any case, the figure of 800 subscribers would make the circulation of Freedom s Journal close to that of other weekly papers of the time Its number of readers, however, would have been much larger: copies were often shared. and African American organizations subscribed to Freedom s Journal, providing nonsubscribers access to the paper
Which of the following, if true, would most lend to undermine Gross ' s argument mentioned in the highlighted portion of the passage?
Female Australian Dunalothrips [small, sap-sucking insects] create tent-like structures on the surface of leaves to protect themselves and their eggs and larvae from desiccation in the arid Australian climate. Bono and Crespi compared survival and reproduction of thrips that founded structures alone with those in groups of two or more individuals. They found that although per capita egg production fell with increasing group size, foundresses were more likely to survive and lay eggs in groups than when alone. Several studies of other species of nest-building insects have concluded that foundress associations are beneficial to all panics. It is likely that the relative success of groups is at least in part accounted for by a reduction of energy use in the modification of a shared nest.
The author suggests which of the following about the " reduction of energy use " ?
What accounts for the low-lying. Hat surface of Mars ' s north? On Earth ' s surface, higher- and lower-lying areas have different types of onest: one. thin and dense, is pulled toward Earth ' s center more strongly by gravity, and the planet ' s water naturally comes to sit over it. creating oceans. The processes that generate this oceanic crust drive plate tectonics.
Is Mars ' s north similarly characterized by a sort of crust different from other areas of the planet? Some researchers do see signs of tectonic activity surrounding the northern basin that suggest that it was created through the formation of new crust, like ocean basins on Earth. However. McGill points to northern bedrock structures that predate the features said to mark the start of the tectonic process. McGill instead believes that through some novel mechanism the ancient surface sank to its current depth as a single unit. This would explain why features around the basin ' s edge. which would have formed as the surface dropped, seem to be younger than structures at its floor.
The third possibility is that the northern lowlands result from impacts. Some researchers suggest they formed as a series of big overlapping impact craters. Others, arguing that the odds against such a pattern of impacts are large, postulate a single event—the impact of an object bigger than any asteroid the solar system now contains.
The passage implies that McGill points to certain " northern bedrock Structures? in order to
People who come to believe false rumors often do so quite (i)_________in the sense mat their new belief
(ii)_________their existing knowledge. This problem is especially acute on the Internet. Rumors often arise and gain
traction because they fit with, and support, the prior convictions of those who accept them.
Economists use two competing models to describe the effects of commercial advertising—advertising as market competition and advertising as market power. The market competition model holds that the fundamental function of advertising is lo provide information about products and brands. It is argued that information in ads permits greater marketplace efficiencies, such as lower prices and reduced monopoly power. In a similar vein, much discussion regarding political advertising has rested on its informational value. Does political advertising provide political information and help voters make informed decisions ' 1 Nelson argues that promoting bars of soap in commercial ads is no different than promoting political ideas ideology from political candidates in political ads. on the grounds that information is being distributed m both cases. Others, such as Ferguson and Jamieson, disagree with Nelson ' s proposition. Ferguson, for example, pointed out that choosing a political candidate is more like buying an experience good (where the quality is hard to evaluate prior to purchase) rather than a search good (where the quality is easily evaluated before the purchase). According to Ferguson, claims in political ads do not have true informational value, because it is difficult for voters to draw inferences about the future deeds of a candidate from what the ads say Furthermore. Jamieson argues that political ads reshape the public image of political candidates and change voters feelings about the candidates with subtle emotional cues but without substantive information upon which to base a reasoned judgment.
In the context of the passage as a whole, the highlighted sentence serves primarily to
Because ii has usually been impossible to_________exotic species once they have become established, it is prudent to minimize the introduction of such species that have a substantial probability of unwanted impacts.
Some archaeologists speculate that the Americas might have been initially colonized between 40.000 and 25.000 years ago. However, to support this theory it is necessary to explain the absence of generally accepted habitation sites for that time interval in what is now the United States. Australia, which has a smaller land area than the United States, has many such sites, supporting the generally accepted claim that the continent was colonized by humans at least 40.000 years ago. Australia is less densely populated (resulting in lower chances of discovering sites) and with its overall greater aridity would have presented conditions less favorable for hunter-gatherer occupation. Proportionally, at least as much land area has been lost from the coastal regions of Australia because of postglacial sea-level rise as in the United States, so any coastal archaeological record in Australia should have been depleted about as much as a coastal record in the United States. Since there are so many resource-rich rivers leading inland from the United States coastline, it seems implausible that a growing population of humans would have confined itself to coasts for thousands of years. If inhabitants were present 25.000 years ago. the chances of their appearing in the archaeological record would seem to be greater than for Australia.
The author of the passage implies that, in what is now the United States, archaeological evidence of inhabitation in the period from 40.000 to 25.000 years ago is lacking because that region
Iii recent years ii has become common for industrial workers who do heavy lifting to wear special wide leather belts that are advertised as reducing back strain. However, physiologists doubt that these belts actually reduce back strain. In fact the belts must put additional strain on the back, since records of injuries to industrial workers show that people wearing the belts were significantly more likely to suffer a back injury than were others doing the same job.
Which of die following, if true, most strengthens the argument?
Robert Philip argues that the advent of recorded music has directed performance style into a search for greater precision and perfection, with a consequent loss of spontaneity and warmth. Various expressive devices once common in classical music have been almost outlawed, including portamento (sliding from one note to another on a stringed instrument), playing the piano with the hands not quite synchronized, and flexibility of tempo. Philip fully documents these changes. However, other forces independent of recording were also at work. For example, the freedom of tempo so valued by Philip was. in its time, both a necessary expedient and disastrously abused. Recording alone did not cause the reaction against it. although hearing a particularly unintelligent use of it on disc may have reinforced the prejudice.
Hie author would most likely agree with which of the following statements about the " devices " ?

The following appeared in a letter from the owner of the Sunnyside Towers apartment complex to its manager.
" Last week, all the showerheads in the first three buildings of the Sunnyside Towers complex were modified to restrict maximum water flow to one-third of what it used to be. Although actual readings of water usage before and after the adjustment are not yet available, the change will obviously result in a considerable savings for Sunnyside Corporation, since the corporation must pay for water each month. Except for a few complaints about low water pressure, no problems with showers have been reported since the adjustment. Clearly, modifying showerheads to restrict water flow throughout all twelve buildings in the Sunnyside Towers complex will increase our profits further. "

Even the most complex models used in fishery management are cartoons of reality. They reduce hundreds of links in food webs to a handful and inadequately represent processes operating over space. Many of their assumptions are as flawed today as those of the simplest models of the past. Fish stocks, for one. are still assumed to be populations of a species that are isolated from one another. Yet many populations mix at their edges and some even migrate through areas occupied by other populations. Furthermore, the more complex models suffer from a " crisis of complexity " —more is really less. Adding layers of detail, each carrying its own set of assumptions, produces instability. The model ' s behavior becomes erratic, and conclusions drawn from it can be downright misleading.
In the context of the passage, the highlighted portion serves to
Origin, distribution, and habitat are included in the book for some but not all of the plants: offering this information for each species would have given readers a clearer appreciation of the differences between _________and introduced species.
Recent research has questioned the long-standing view of pearly mussels as exclusively suspension feeders (animals that strain suspended particles from water) that subsist on phytoplankton (mostly algae). Early studies of mussel feeding were based on analyses of gut contents, a method that has three weaknesses. First, material in mucus-bound gut contents is difficult to identify and quantify. Second, material found in the gut may pass undigested out of the mussel, not contributing to its nutrition. Finally, examination of gut contents offers limited insight into the mechanisms and behaviors by which mussels acquire food. Modem studies suggest that pearly mussels feed on more than just algae and may use other means than suspension feeding. Pedal feeding (sweeping up edible material with a muscular structure called the foot) has been observed in juvenile pearly mussels.
Besides the phytoplankton pearly mussels capture from the water column, their guts also contain small animals, protozoans, and detritus (nonliving particulate organic material). Recent studies show that mussels can capture and assimilate bacteria as well, a potentially important source of food in many fresh waters. Another potential source of food for mussels is dissolved organic matter. Early studies showing that pearly mussels could take up simple organic compounds were largely discounted because such labile (unstable) compounds are rarely abundant in nature. Nevertheless, recent work on other bivalves suggests that dissolved organic matter may be a significant source of nutrition.
Of this complex mix of materials that pearly mussels acquire, what is actually required and assimilated? Stable-isotope analyses of mussels taken from nature and of captive-reared mussels are beginning to offer some insight into this question. Nichols and Garling showed that pearly mussels in a small river were omnivorous, subsisting mainly on particles less than 2S micrometers in diameter, including algae, detritus, and bacteria. Bacterially derived carbon was apparently the primary source of soft-tissue carbon. However, bacteria alone cannot support mussel growth, because they lack the necessary long-chain fatty acids and sterols and are deficient in some amino acids. Bacteria may supplement other food resources, provide growth factors, or be the primary food In habitats such as headwater streams, where phytoplankton is scarce. Juvenile mussels have been most successfully reared m the laboratory on diets containing algae high in polyunsaturated fatty acids. Thus, it appears that the pearly mussel diet in nature may consist of algae, bacteria, detritus, and small animals and that at least some algae and bacteria may be required as a source of essential biochemicals.
The passage mentions which of the following as a factor that limits the information researchers can glean from analyzing gut contents?
Instances of " galactic cannibalism " —mergers in which large galaxies completely consume smaller ones—may be fairly common. Tidal forces produced by the Milky Way ' s powerful gravity, for example, appear to be dismantling and engulfing a dwarf galaxy in the constellation Sagittarius, producing large clumps and streamers of stars connecting the two galaxies. Astronomers have also observed two dense clusters of stars and gas at the heart of the Andromeda galaxy, an apparent " double nucleus " that may contain the remnant of a cannibalized dwarf galaxy. But this Twin-lobed appearance could also be created by two parts of a single nucleus bisected by a lane of dust. Scientists believe that only about 25 percent of such apparent double nuclei actually represent galactic cannibalism. Many of the rest result from the illusion of proximity that occurs when objects at different distances appear along the same line of sight: others consist of debris from galactic " collisions. " in which one galaxy has passed through another without merging, causing waves of new star formation.
According to the passage, a true double nucleus may be produced by the

Sunflower sea slurs help maintain certain kelp forest ecosystems by eating quickly reproducing prey species such as urchins, thus keeping populations low. Without the sea stars, the urchin population explodes, which is bad news for kelp forests and everything in them. Giant kelp can grow to 150 feet underwater at a speed of two feet a day. but their weaknesses are their holdfasts. which are akin to tree roots. The holdfasts are home to brittle stars, prawns, and snails, among other creatures. Urchins like to eat the kelp holdfasts. Once the holdfasts are gone, the rest of the kelp drifts oft* in the tides. In this way. urchins can destroy the forests, which, higher up. are also home to fish, including several types of commercially important rockfish.
According to the passage, sea urchin populations

Carbon dating of charcoal gathered from a Nok iron smelter at Intime. Nigeria, suggests that iron technology was established there by 410 B.C. This may not be the oldest smelter in sub-Saharan Africa, however. Archaeologists have located evidence of iron-smelting in the Termite Hills of Niger from as early as 1400 B.C.. but skeptics say the wood used for that dating could have already been centuries old when burned as fuel—a problem that dogs carbon dating, especially in arid places like Niger, where wood desiccates and lasts longer. Of course, the same problem could distort dates for the Intime furnace as well, but here there is an important piece of corroborating evidence: Nok pottery found inside the furnace alongside the charcoal.
The author implies which of the following about the " Nok pottery found inside the furnace " ?
