题目：

Rev. Hayes says that an action is right if it benefits one or more other people and an action is wrong if it harms anyone. Rev. Hayes says the action is wrong if the harm could have been seen with reasonable thought or whether or not harm was intended to anyone.
Which one of the following most clearly conforms to the principle cited above?

选项:

A、A. Frank wrote a proposal attempting to cause trouble between Linda and Jane; this action was morally bad, even though, in fact, it had an opposite effect than the one intended.
B、B. Giving a homeless man a ride to a local shelter, Fred was in a serious car accident that was not his fault. The homeless man, injured in the accident, received a settlement from the other driver's insurance company. The settlement allowed him to get an apartment for him and his family; thus showing that a right action can have both bad and good consequences.
C、C. Giving a homeless man a ride to a local shelter, George was in a serious car accident that was his fault. The homeless man, injured in the accident, received a settlement from George's insurance company. The settlement allowed him to get an apartment for him and his family; thus showing that a right action can have both bad and good consequences.
D、D. Linda agreed to watch her friend's cat for two weeks at her home. Everything went fine for 10 days. Then, on the next day, when Linda opened the window and sat down to watch television, the cat fell out of the window and was injured. She took the cat to a local vet, paid the bill, and the cat was almost recovered by the time Linda's friend returned. Even though she intended no harm, Linda's action was wrong.
E、E. Mary, a trained social worker, was asked by a homeless man for food. She walked with the man to the local shelter that runs a soup kitchen. There, the man choked while eating lunch and died. Thus, Mary performed a wrong action.

文章：

Line         Two works published in 1984 demonstrate
  contrasting approaches to writing the history of
  United States women. Buel and Buel’s biography
  of Mary Fish (1736–1818) makes little effort to
(5) place her story in the context of recent
  historiography on women. Lebsock, meanwhile,
  attempts not only to write the history of women in
  one southern community, but also to redirect two
  decades of historiographical debate as to
(10) whether women gained or lost status in the
  nineteenth century as compared with the
  eighteenth century. Although both books offer the
  reader the opportunity to assess this controversy
  regarding women’s status, only Lebsock’s deals with
(15) it directly. She examines several different aspects
  of women’s status, helping to refine and resolve the
  issues. She concludes that while
  women gained autonomy in some areas,
  especially in the private sphere, they lost it in
(20) many aspects of the economic sphere. More
  importantly, she shows that the debate itself
  depends on frame of reference: in many respects,
  women lost power in relation to men, for example,
  as certain jobs (delivering babies, supervising
(25) schools) were taken over by men. Yet women also
  gained power in comparison with their previous
  status, owning a higher proportion of real estate,
  for example. In contrast, Buel and Buel’s
  biography provides ample raw material for
(30) questioning the myth, fostered by some
  historians, of a colonial golden age in the
  eighteenth century but does not give the reader
  much guidance in analyzing the controversy over
  women’s status.


题目：

The passage suggests that Lebsock believes that compared to nineteenth-century American women, eighteenth-century American women were

选项:

A、in many respects less powerful in relation to men
B、more likely to own real estate
C、generally more economically independent
D、more independent in conducting their private lives
E、less likely to work as school superintendents

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：

Which of the following, if true, would most clearly support the contention attributed to SPEW in lines 17–20 ?

选项:

A、Those white lead factories that most strongly enforced regulations concerning worker safety and hygiene had the lowest incidences of lead poisoning among employees.
B、The incidence of lead poisoning was much higher among women who worked in white lead factories than among women who worked in other types of factories.
C、There were many household sources of lead that could have contributed to the incidence of lead poisoning among women who also worked outside the home in the late nineteenth century.
D、White lead factories were more stringent than were certain other types of factories in their enforcement of workplace safety regulations.
E、Even brief exposure to the conditions typically found in white lead factories could cause lead poisoning among factory workers.

A

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?
