题目：

Thyrian lawmaker: Thyria's Cheese Importation Board inspects all cheese shipments to Thyria and rejects shipments not meeting specified standards. Yet only 1 percent is ever rejected. Therefore, since the health consequences and associated economic costs of not rejecting that 1 percent are negligible, whereas the board's operating costs are considerable, for economic reasons alone the board should be disbanded.

Consultant: I disagree. The threat of having their shipments rejected deters many cheese exporters from shipping substandard product.

The consultant responds to the lawmaker's argument by

选项:

A、rejecting the lawmaker's argument while proposing that the standards according to which the board inspects imported cheese should be raised
B、providing evidence that the lawmaker's argument has significantly overestimated the cost of maintaining the board
C、objecting to the lawmaker's introducing into the discussion factors that are not strictly economic
D、pointing out a benefit of maintaining the board, which the lawmaker's argument has failed to consider
E、shifting the discussion from the argument at hand to an attack on the integrity of the cheese inspectors

Manufacturers sometimes discount the price of a product to retailers for a promotion period when the product is advertised to consumers.Such promotions often result in a dramatic increase in amount of product sold by the manufacturers to retailers.Nevertheless.the manufacturers could often make more profit by not holding the promotions.

题目：

Which of the following, if true, most strongly supports the claim above about the manufacturers' profit?

选项:

A、The amount of discount generally offered by manufacturers to retailers is carefully calculated to represent the minimum needed to draw consumers' attention to the product. For many consumer products the period of advertising discounted prices to consumers is about a week.not sufficiently long for consumers to become used to the sale price. 
B、For products that are not newly introduced. the purpose of such promotions is to keep the products in the minds of consumers and to attract consumers who are currently using competing products. 
C、During such a promotion retailers tend to accumulate in their warehouses inventory bought at discount；they then sell much of it later at their regular price.
D、If a manufacturer fails to offer such promotions but its competitor offers them, that competitor will tend to attract consumers away from the manufacturer's product.

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 implies that the women studied by Krontiris are unusual in which of the following ways?

选项:

A、They faced obstacles less formidable than those faced by other Renaissance women.
B、They have been seen by historians as more interesting than other Renaissance women.
C、They were more concerned about recording history accurately than were other Renaissance women.
D、Their perceptions are more likely to be accessible to historians than are those of most other Renaissance women.
E、Their concerns are likely to be of greater interest to feminist scholars than are the ideas of most other Renaissance women.

D

文章：

Line         Acting on the recommendation of a British
  government committee investigating the high
  incidence in white lead factories of illness among
  employees, most of whom were women, the Home
(5) Secretary proposed in 1895 that Parliament enact
  legislation that would prohibit women from holding
  most jobs in white lead factories. Although the
  Women’s Industrial Defence Committee (WIDC),
  formed in 1892 in response to earlier legislative
(10) attempts to restrict women’s labor, did not discount
  the white lead trade’s potential health dangers, it
  opposed the proposal, viewing it as yet another
  instance of limiting women’s work opportunities.
       Also opposing the proposal was the Society for
(15) Promoting the Employment of Women (SPEW),
  which attempted to challenge it by investigating the
  causes of illness in white lead factories. SPEW
  contended, and WIDC concurred, that controllable
  conditions in such factories were responsible for
(20) the development of lead poisoning. SPEW provided
  convincing evidence that lead poisoning could be
  avoided if workers were careful and clean and if
  already extant workplace safety regulations were
  stringently enforced. However, the Women’s Trade
(25) Union League (WTUL), which had ceased in the late
  1880s to oppose restrictions on women’s labor,
  supported the eventually enacted proposal, in part
  because safety regulations were generally not being
  enforced in white lead factories, where there were
(30) no unions (and little prospect of any) to pressure
  employers to comply with safety regulations.


题目：

The passage suggests that WIDC differed from WTUL in which of the following ways?

选项:

A、WIDC believed that the existing safety regulations were adequate to protect women’s health, whereas WTUL believed that such regulations needed to be strengthened.
B、WIDC believed that unions could not succeed in pressuring employers to comply with such regulations, whereas WTUL believed that unions could succeed in doing so.
C、WIDC believed that lead poisoning in white lead factories could be avoided by controlling conditions there, whereas WTUL believed that lead poisoning in such factories could not be avoided no matter how stringently safety regulations were enforced.
D、At the time that the legislation concerning white lead factories was proposed, WIDC was primarily concerned with addressing health conditions in white lead factories, whereas WTUL was concerned with improving working conditions in all types of factories.
E、At the time that WIDC was opposing legislative attempts to restrict women’s labor, WTUL had already ceased to do so.

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?
