文章：

Colonial historian David Allen's intensive study of five communities in seventeenth-century Massachusetts is a model of meticulous scholarship on the detailed microcosmic level, and is convincing up to a point.  Allen suggests that much more coherence and direct continuity existed between English and colonial agricultural practices and administrative organization than other historians have suggested.  However, he overstates his case with the declaration that he has proved "the remarkable extent to which diversity in New England local institutions was directly imitative of regional differences in the mother country."
 
Such an assertion ignores critical differences between seventeenth-century England and New England.  First, England was overcrowded and land-hungry; New England was sparsely populated and labor-hungry.  Second, England suffered the normal European rate of mortality; New England, especially in the first generation of English colonists, was virtually free from infectious diseases.  Third, England had an all-embracing state church; in New England membership in a church was restricted to the elect.  Fourth, a high proportion of English villagers lived under paternalistic resident squires; no such class existed in New England.  By narrowing his focus to village institutions and ignoring these critical differences, which studies by Greven, Demos, and Lockridge have shown to be so important, Allen has created a somewhat distorted picture of reality.
 
Allen's work is a rather extreme example of the "country community" school of seventeenth-century English history whose intemperate excesses in removing all national issues from the history of that period have been exposed by Professor Clive Holmes.  What conclusion can be drawn, for example, from Allen's discovery that Puritan clergy who had come to the colonies from East Anglia were one-third to one-half as likely to return to England by 1660 as were Puritan ministers from western and northern England?  We are not told in what way, if at all, this discovery illuminates historical understanding.  Studies of local history have enormously expanded our horizons, but it is a mistake for their authors to conclude that village institutions are all that mattered, simply because their functions are all that the records of village institutions reveal.

选项:

A、already known to earlier historians

题目：

Astronomer:  Observations of the Shoemaker-Levi comet on its collision course with Jupiter showed that the comet broke into fragments before entering Jupiter's atmosphere in 1994, but they did not show how big those fragments were.  Nevertheless, some indication of their size can be inferred from spectrographic analyses of Jupiter's outer atmosphere.  After the fragments' entry, these analyses revealed unprecedented traces of sulfur.  The fragments themselves almost certainly contained no sulfur, but astronomers believe that the cloud layer below Jupiter's outer atmosphere does contain sulfur.  Since sulfur would have seeped into the outer atmosphere if comet fragments had penetrated this cloud layer, it is likely that some of the fragments were at least large enough to have passed through Jupiter's outer atmosphere without being burned up.
 
In the astronomer's argument, the two portions in boldface play which of the following roles?

选项:

A、The first is a claim that the astronomer seeks to show is true; the second acknowledges a consideration that weighs against the truth of that claim.
B、The first is a claim that the astronomer seeks to show is true; the second provides evidence in support of the truth of that claim.
C、The first and the second are each considerations advanced in support of the conclusion of the argument.
D、The first provides evidence in support of the conclusion of the argument; the second is that conclusion.
E、The first is a circumstance for which the astronomer seeks to provide an explanation; the second acknowledges a consideration that weighs against the explanation provided by the astronomer.

题目：

A prominent investor who holds a large stake in the Burton Tool Company has recently claimed that the company is mismanaged, citing as evidence the company's failure to slow production in response to a recent rise in its inventory of finished products.  It is doubtful whether an investor's sniping at management can ever be anything other than counterproductive, but in this case it is clearly not justified.  It is true that an increased inventory of finished products often indicates that production is outstripping demand, but in Burton's case it indicates no such thing.  Rather, the increase in inventory is entirely attributable to products that have already been assigned to orders received from customers.

文章：

Since it has become known that several of a bank's top executives have been buying shares in their own bank, the bank's depositors, who had been worried by rumors that the bank faced impending fi nancial collapse, have been greatly relieved. They reason that, since top executives evidently have faith in the bank’s fi nancial soundness, those worrisome rumors must be false. Such reasoning might well be overoptimistic, however, since corporate executives have been known to buy shares in their own company in a calculated attempt to dispel negative rumors about the company's health.

In the argument given, the two boldfaced portions play which of the following roles?

A、The first describes evidence that has been taken as supporting a conclusion; the second gives a reason for questioning that support. The first describes evidence that has been taken as supporting a conclusion; the second states a contrary conclusion that is the main conclusion of the argument. 
B、The first provides evidence in support of the main conclusion of the argument; the second states that conclusion. 
C、The first describes the circumstance that the argument as a whole seeks to explain; the second gives the explanation that the argument seeks to establish. 
D、The first describes the circumstance that the argument as a whole seeks to explain; the second provides evidence in support of the explanation that the argument seeks to establish.

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?
