题目：

Veterinarians generally derive some of their income from selling several manufacturers' lines of pet-care products. Knowing that pet owners rarely throw away mail from their pet's veterinarian unread, one manufacturer of pet-care products offered free promotional materials on its products to veterinarians for mailing to their clients. Very few veterinarians accepted the offer, however, even though the manufacturer's products are of high quality.

Which of the following, if true, most helps to explain the veterinarians' reaction to the manufacturer's promotional scheme?

选项:

A、Most of the veterinarians to whom the free promotional materials were offered were already selling the manufacturer's pet-care products to their clients.
B、The special promotional materials were intended as a supplement to the manufacturer's usual promotional activities rather than as a replacement for them.
C、The manufacturer's products, unlike most equally good competing products sold by veterinarians, are also available in pet stores and in supermarkets.
D、Many pet owners have begun demanding quality in products they buy for their pets that is as high as that in products they buy for themselves.
E、Veterinarians sometimes recommend that pet owners use products formulated for people when no suitable product specially formulated for animals is available.

题目：

Hea Sook: One should not readily believe urban legends. Most legends are propagated because the moral lesson underlying them supports a political agenda. People will repeat a tale if it fits their purpose. They may not deliberately spread untruths, but neither are they particularly motivated to investigate deeply to determine if the tale they are telling is true.

Kayla: But people would not repeat stories that they did not believe were true. Therefore, one can safely assume that if a story has been repeated by enough people then it is more likely to be true.

Kayla's reply is most vulnerable to the criticism that it

选项:

A、does not specify how many people need to repeat a story before someone is justified believing it
B、overstates the significance of political agendas in the retelling of stories
C、fails to address the claim that people will not verify the truth of a story that fits their purpose
D、implicitly supports the claim that the people repeating legends are not deliberately spreading untruths
E、cannot distinguish people's motivations for repeating urban legends from their motivations for repeating other types of story

题目：

Researchers took a group of teenagers who had never smoked and for one year tracked whether they took up smoking and how their mental health changed.  Those who began smoking within a month of the study's start were four times as likely to be depressed at the study's end than those who did not begin smoking.  Since nicotine in cigarettes changes brain chemistry, perhaps thereby affecting mood, it is likely that smoking contributes to depression in teenagers.
 
Which of the following, if true, most strengthens the argument?

选项:

A、Participants who were depressed at the study's start were no more likely to be smokers at the study's end than those who were not depressed.
B、Participants who began smoking within a month of the study's start were no more likely than those who began midway through to have quit smoking by the study's end.
C、Few, if any, of the participants in the study were friends or relatives of other participants.
D、Some participants entered and emerged from a period of depression within the year of the study.
E、The researchers did not track use of alcohol by the teenagers.

题目：

Most household appliances use electricity only when in use.  Many microwave ovens, however, have built-in clocks and so use some electricity even when they are not in use.  The clocks each consume about 45 kilowatt-hours per year.  Therefore, households whose microwave oven has no built-in clock use 45 kilowatt-hours per year less, on average, than do comparable households whose microwave oven is otherwise similar but has a built-in clock.
Which of the following is an assumption on which the argument depends?

选项:

A、Households that do not have a microwave oven use less energy per year, on average, than do households that have a microwave oven.
B、Microwave ovens with a built-in clock do not generally cost more to buy than microwave ovens without a built-in clock.
C、All households that have a microwave oven also have either a gas oven or a conventional electric oven.
D、Households whose microwave oven does not have a built-in clock are no more likely to have a separate electric clock plugged in than households whose microwave oven has one.
E、There are more households that have a microwave oven with a built-in clock than there are households that have a microwave oven without a built-in clock.

文章：

    First identified in 1969, komatiites are Earth's oldest known volcanic rocks and contain three times as much magnesium as do most volcanic rocks. This chemical composition suggests that komatiites formed from the hottest lava known ever to have erupted:a high concentration of magnesium changes the physical properties of lava so that unusually high temperatures would be required for the lava to exist as a liquid.

    Komatiites' discovery was surprising in light of then-current geological theories about magmas, molten rock that forms in the Earth's mantle (the layer beneath the crust) and composes volcanic lava eruptions. Prior to 1960, geologists Bowen and Hess disagreed over whether or not the very high temperatures needed to produce magmas rich in magnesium could have existed on Earth. Hess suggested that the presence of water, probably released from minerals decomposing in the Earth's mantle, might have meant that a high-magnesium magma could have existed at a lower temperature. But Bowen showed experimentally that the high temperatures were indeed necessary. By 1960, it was generally accepted that volcanic rocks with such high levels of magnesium could not exist, and thus the discovery of koma tiites changed geologists' assumptions about the characteristics of the Earth's mantle around the time of the formation of komatiites, between 2.5 and 4 billion years ago.

题目：

Information in the passage suggests which of the following concerning the Earth's mantle 2.5 to 4 billion years ago?

选项:

A、It contained magmas that were more significantly affected by the decomposition of minerals than are current-day magmas.
B、It contained a lower proportion of water that it contains today.
C、Its characteristics were accurately described by both Bowen and Hess.
D、Its temperature was sufficiently high to produce magmas with high magnesium content.
E、Its total magnesium content then was roughly equivalent to its magnesium content today.

文章：

Line         In 1955 Maurice Duverger published The Political
  Role of Women, the first behavioralist, multinational
  comparison of women’s electoral participation ever to
  use election data and survey data together.
(5) His study analyzed women’s patterns of voting,
  political candidacy, and political activism in four
  European countries during the first half of the
  twentieth century. Duverger’s research findings
  were that women voted somewhat less frequently
(10) than men (the difference narrowing the longer
  women had the vote) and were slightly more
  conservative.
       Duverger’s work set an early standard for the
  sensitive analysis of women’s electoral activities.
(15) Moreover, to Duverger’s credit, he placed his
  findings in the context of many of the historical
  processes that had shaped these activities.
  However, since these contexts have changed over
  time, Duverger’s approach has proved more durable
(20) than his actual findings. In addition, Duverger’s
  discussion of his findings was hampered by his failure
  to consider certain specific factors important to
  women’s electoral participation at the time he
  collected his data: the influence of political regimes,
(25) the effects of economic factors, and the
  ramifications of political and social relations between
  women and men. Given this failure, Duverger’s
  study foreshadowed the enduring limitations of the
  behavioralist approach to the multinational study of
(30) women’s political participation.


题目：

The author implies that Duverger’s actual findings are

选项:

A、limited because they focus on only four countries
B、inaccurate in their description of the four countries in the early 1950s
C、out-of-date in that they are inapplicable in the four countries today
D、flawed because they are based on unsound data
E、biased by Duverger’s political beliefs

文章：

Line         Jacob Burckhardt’s view that Renaissance
  European women “stood on a footing of perfect
  equality” with Renaissance men has been repeatedly
  cited by feminist scholars as a prelude to their
(5) presentation of rich historical evidence of women’s
  inequality. In striking contrast to Burckhardt, Joan
  Kelly in her famous 1977 essay, “Did Women Have
  a Renaissance?” argued that the Renaissance was
  a period of economic and social decline for women
(10) relative both to Renaissance men and to medieval
  women. Recently, however, a significant trend
  among feminist scholars has entailed a rejection
  of both Kelly’s dark vision of the Renaissance and
  Burckhardt’s rosy one. Many recent works by these
(15) scholars stress the ways in which differences
  among Renaissance women—especially in terms
  of social status and religion—work to complicate
  the kinds of generalizations both Burckhardt and
  Kelly made on the basis of their observations about
(20) upper-class Italian women.
       The trend is also evident, however, in works
  focusing on those middle- and upper-class
  European women whose ability to write gives them
  disproportionate representation in the historical
(25) record. Such women were, simply by virtue of
  their literacy, members of a tiny minority of the
  population, so it is risky to take their descriptions of
  their experiences as typical of “female experience”
  in any general sense. Tina Krontiris, for example, in
(30) her fascinating study of six Renaissance women
  writers, does tend at times to conflate “women” and
  “women writers,” assuming that women’s gender,
  irrespective of other social differences, including
  literacy, allows us to view women as a homogeneous
(35) social group and make that group an object of
  analysis. Nonetheless, Krontiris makes a significant
  contribution to the field and is representative of
  those authors who offer what might be called a
  cautiously optimistic assessment of Renaissance
(40) women’s achievements, although she also stresses
  the social obstacles Renaissance women faced
  when they sought to raise their “oppositional
  voices.” Krontiris is concerned to show women
  intentionally negotiating some power for themselves
(45) (at least in the realm of public discourse) against
  potentially constraining ideologies, but in her sober
  and thoughtful concluding remarks, she suggests
  that such verbal opposition to cultural stereotypes
  was highly circumscribed; women seldom attacked
(50) the basic assumptions in the ideologies that
  oppressed them.


题目：

The author of the passage discusses Krontiris primarily to provide an example of a writer who

选项:

A、is highly critical of the writings of certain Renaissance women
B、supports Kelly’s view of women’s status during the Renaissance
C、has misinterpreted the works of certain Renaissance women
D、has rejected the views of both Burckhardt and Kelly
E、has studied Renaissance women in a wide variety of social and religious contexts

Art historian: Unlike many artistic traditions that sought to depict plants native to the local area in a seasonally appropriate way (for example, depicting scenes of spring with the plants in the appropriate stages of development for that season), seventeenth-century Dutch artists specializing in flower paintings almost exclusively chose to depict exotic species of flowers from outside the local area. Painting such species was worthwhile primarily because the art-buying public had developed a strong preference for images of the exotic. The great botanical centers of the time gave the artists direct access to such flowers, which the artists would freely combine in a single painting, regardless of whether the combined species occurred together in the wild, and depicted each in full bloom, regardless of whether those species bloomed at the same time in nature.

Statement: The art historian makes the point that the species of flowers these Dutch artists chose to paint were 1 largely because the species were 2 .

Select for 1 and for 2 the options that complete the statement so that it is most strongly supported by the information provided. Make only two selections, one in each column.

Tiger beetles are such fast runners that they can capture virtually any nonflying insect.  However, when running toward an insect, the beetles intermittently stop, and then, a moment later, resume their attack.  Perhaps they 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 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?
