文章：

Line Linda Kerber argued in the mid-1980s that after
the American Revolution (1775–1783), an ideology
of “republican motherhood” resulted in a surge of
educational opportunities for women in the United
(5) States. Kerber maintained that the leaders of
the new nation wanted women to be educated in
order to raise politically virtuous sons. A virtuous
citizenry was considered essential to the success
of the country's republican form of government;
(10) virtue was to be instilled not only by churches and
schools, but by families, where the mother's role
was crucial. Thus, according to Kerber, motherhood
became pivotal to the fate of the republic, providing
justification for an unprecedented attention to female
(15) education.
Introduction of the “republican motherhood”
thesis dramatically changed historiography. Prior
to Kerber's work, educational historians barely
mentioned women and girls; Thomas Woody's
(20) 1929 work is the notable exception. Examining
newspaper advertisements for academies, Woody
found that educational opportunities increased for
both girls and boys around 1750. Pointing to “An
Essay on Woman” (1753) as reflecting a shift in
(25) view, Woody also claimed that practical education
for females had many advocates before the
Revolution. Woody's evidence challenges the notion
that the Revolution changed attitudes regarding
female education, although it may have accelerated
(30) earlier trends. Historians’ reliance on Kerber's
“republican motherhood” thesis may have obscured
the presence of these trends, making it difficult
to determine to what extent the Revolution really
changed women's lives.

题目：

The passage suggests that, with regard to the history of women's education in the United States, Kerber's work differs from Woody's primarily concerning which of the following?

选项:

A、The extent to which women were interested in pursuing educational opportunities in the eighteenth century
B、The extent of the support for educational opportunities for girls prior to the American Revolution
C、The extent of public resistance to educational opportunities for women after the American Revolution
D、Whether attitudes toward women's educational opportunities changed during the eighteenth century
E、Whether women needed to be educated in order to contribute to the success of a republican form of government

答案:

B

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?
