Admission Tests GRE General Test Sample Questions:

Question #1
The term "ragtime opera" was used frequently m the first years of the twentieth century, but more often than not its use was (i)_________. The very idea of "ragtime opera" was viewed as lii)_________: opera was regarded as the highest form of musical art; ragtime was at the opposite pole.

A. facetious
B. cliche
C. a self-contradiction
D. an abstraction
E. an exaggeration
F. unambiguous

Question #2
Female Australian Duiiatothrip.% (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 tlirips 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 parties. 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 would most likely agree with which of the following claims about Australian Drmatolhrips ?

A. Their offspring survival rates increase when larger groups cooperate to modify nests.
B. They modify nests in different ways depending on what other species are present in their vicinity.
C. They expend as much energy to create tent-like structures as they do to produce broods.
D. They exhibit an effect from collective activity that is also found in certain other insect species.
E. Their effect on the leaves used to support their tent-like structures is not necessarily permanent

Question #3
Last year a fanner used of the farm's wheat crop for cattle feed and sold of the remaining amount to a flour mill. Of the wheat sold to the mill, , or 750 bushels, was milled into whole wheat flour. What was the total amount, in bushels, of the farm's wheat crop last year?

A. 1.200
B. 2.400
C. 4.800
D. 1.600
E. 3.200

Question #4
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

A. waves of new star formation resulting from an instance of galactic cannibalism
B. separation of a single nucleus into two parts by a lane of dust
C. merging of two galaxies of approximately equal size
D. incorporation of a dwarf galaxy into a larger galaxy
E. collision of two dwarf galaxies

Question #5
As originally formulated, the selfish-herd theory of prey species aggregation assumed that predatory attacks were equally likely to be launched from any position within the environment. In some circumstances (e.g..
avian predators attacking prey from above), such an approach is appropriate. However, as James et at. argue, in many predator-prey associations, attacks are unlikely to occur from positions within the group. For example, it is likely that an ambushing predator waiting in the path of a group would be detected before the group moves over its position. Hence, in many ecological situations, predatory attacks on grouped prey will occur exclusively from outside the group. In such circumstances, there is a strong premium to a group member in being in the interior of the group.
The passage suggests that compared to members of the prey groups in "some circumstances." certain members of the prey groups in "many ecological situations" are likely to be less

A. able to reach escape routes to avoid predators
B. skilled at detecting ambushing predators
C. vulnerable to predator attacks
