题目:

For the period from the eighth century through the eleventh century, the shifting boundaries between Kingdom F and Kingdom G have not been well charted. Although a certain village in a border region between the two kingdoms usually belonged to Kingdom G, ninth-century artifacts found in the village were in the typical Kingdom F style of that time. It is unclear whether the village was actually a part of Kingdom F in the ninth century or whether it was a part of Kingdom G but had merely adopted Kingdom F's artistic styles under Kingdom F's cultural influence.

Which of the following would, if found in ninth-century sites in the village, best help in determining whether the village was a part of Kingdom F or Kingdom G in the ninth century?

选项:

A、A trading contract written in the Kingdom G dialect
B、A drawing of a dwelling complex known to have existed on the border of Kingdom F and Kingdom G in the ninth century
C、Knives and other utensils made from metal typical of ninth-century mining sites in Kingdom F
D、Some fragments of pottery made in the Kingdom G style from the seventh century out of materials only found in Kingdom F
E、Numerous teeth from the ninth century with a chemical signature typical only of teeth from people who had grown up in the heart of Kingdom F

E

题目:

When a caterpillar emerges from the egg on a tree branch, it immediately climbs upward until it finds a leaf bud to eat.  Biologists thought that this behavior displayed an innate tendency to move in the direction opposite to the pull of gravity.  In a recent experiment, a strong light source was placed at the bottom of a tree, and caterpillars, after hatching, climbed downward.
 
Which of the following hypotheses is best supported by the statements given?

选项:

A、Caterpillars have an innate tendency to move in the direction of gravity.
B、Newly hatched caterpillars are unable to see in the dark.
C、Newly hatched caterpillars move towards the strongest light source in the environment.
D、Newly hatched caterpillars move toward the leaf bud nearest to them.
E、The eyes of newly hatched caterpillars become less sensitive to light over time.

文章:

    When the history of women began to receive focused attention in the 1970', Eleanor Roosevelt was one of a handful of female Americans who were well known to both historians and the general public. Despite the evidence that she had been important in socialreform circles before her husband was elected President and that she continued to advocate different causes than he did, she held a place in the public imagination largely because she was the wife of a particularly influential President. Her own activities were seen as preparing the way for her husband's election or as a complement to his programs. Even Joseph Lash's two volumes of Sympathetic biography, Eleanor and Franklin (1971) and Eleanor: The Years Alone (1972), reflected this assumption.

    Lash's biography revealed a Complicated woman who sought Through political activity both to flee inner misery and to promote causes in which she passionately believed. However, she still appeared to be an idiosyncratic figure, somehow self-generated not amenable to any generalized explanation. She emerged from the biography as a mother to the entire nation, or as a busybody. but hardly as a social type, a figure comprehensible in terms of broader social developments.

    But more recent work on the feminism of the post-suffrage years (following 1920) allows us to see Roosevelt in a different light and to bring her life into a more richly detailed context. Lois Scharf's Eleanor Roosevelt, written In 1987, depicts a generation of Privileged women, born in the late Nineteenth century and maturing in the twentieth, who made the transition from old patterns of female association to new ones. Their views and their lives were full Of contradictions. They maintained female social networks but began to integrate women into mainstream politics; they demanded equal treatment but also argued that women's maternal responsibilities made them both wards and representatives of the public interest. Thanks to Scharf and others, Roosevelt's activities—for example, her support both for labor laws protecting women and for appointments of women to high public office—have become intelligible in terms of this social context rather than as the idiosyncratic career of a famous man's wife.

题目:

Which of the following studies would proceed in a way most similar to the way in which, according to the passage. Scharf's book interprets Eleanor Roosevelt's career?

选项:

A、An exploration of the activities of a wealthy social reformer in terms of the ideals held by the reformer
B、A history of the leaders of a political party which explained how the conflicting aims of its individual leaders thwarted and diverted the activities of each leader
C、An account of the legislative career of a conservative senator which showed his goals to have been derived from a national conservative movement of which the senator was a part
D、A biography of a famous athlete which explained her high level of motivation in terms of the kind of family in which she grew up
E、A history of the individuals who led the move ment to end slavery in the United States which attributed the movement's success to the efforts of those exceptional individuals

题目:

Meteorologists say that if only they could design an accurate mathematical model of the atmosphere with all its complexities, they could forecast the weather with real precision. But this is an idle boast, immune to any evaluation, for any inadequate weather forecast would obviously be blamed on imperfections in the model.

Which of the following, if true, could best be used as a basis for arguing against the author’s position that the meteorologists’ claim cannot be evaluated?

选项:

A、Certain unusual configurations of data can serve as the basis for precise weather forecasts, even though the exact causal mechanisms are not understood.
B、Most significant gains in the accuracy of the relevant mathematical models are accompanied by clear gains in the precision of weather forecasts.
C、Mathematical models of the meteorological aftermath of such catastrophic events as volcanic eruptions are beginning to be constructed.
D、Modern weather forecasts for as much as a full day ahead are broadly correct about 80 percent of the time.
E、Meteorologists readily concede that the accurate mathematical model they are talking about is not now in their power to construct.

题目:

A company plans to develop a prototype weeding machine that uses cutting blades with optical sensors and microprocessors that distinguish weeds from crop plants by differences in shade of color.  The inventor of the machine claims that it will reduce labor costs by virtually eliminating the need for manual weeding.
 
Which of the following is a consideration in favor of the company's implementing its plan to develop the prototype?

选项:

A、There is a considerable degree of variation in shade of color between weeds of different species.
B、The shade of color of some plants tends to change appreciably over the course of their growing season.
C、When crops are weeded manually, overall size and leaf shape are taken into account in distinguishing crop plants from weeds.
D、Selection and genetic manipulation allow plants of virtually any species to be economically bred to have a distinctive shade of color without altering their other characteristics.
E、Farm laborers who are responsible for the manual weeding of crops carry out other agricultural duties at times in the growing season when extensive weeding is not necessary.

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?
