Line    According to economic signaling theory,
  consumers may perceive the frequency with
  which an unfamiliar brand is advertised as a cue
  that the brand is of high quality. The notion that
(5) highly advertised brands are associated with
  high-quality products does have some empirical
  support. Marquardt and McGann found that
  heavily advertised products did indeed rank high
  on certain measures of product quality. Because
(10) large advertising expenditures represent
  a significant investment on the part of a
  manufacturer, only companies that expect to
  recoup these costs in the long run, through
  consumers’ repeat purchases of the product,
(15) can afford to spend such amounts.
       However, two studies by Kirmani have found
  that although consumers initially perceive expensive
  advertising as a signal of high brand quality,
  at some level of spending the manufacturer’s
(20) advertising effort may be perceived as unreasonably
  high, implying low manufacturer confidence in
  product quality. If consumers perceive excessive
  advertising effort as a sign of a manufacturer’s
  desperation, the result may be less favorable
(25) brand perceptions. In addition, a third study by
  Kirmani, of print advertisements, found that the
  use of color affected consumer perception of
  brand quality. Because consumers recognize that
  color advertisements are more expensive than
(30) black and white, the point at which repetition of an
  advertisement is perceived as excessive comes
  sooner for a color advertisement than for a blackand-
  white advertisement.


题目：

The primary purpose of the passage is to

选项:

A、present findings that contradict one explanation for the effects of a particular advertising practice

C、discuss how and why particular advertising practices may affect consumers’ perceptions
D、contrast the research methods used in two different studies of a particular advertising practice
E、explain why a finding about consumer responses to a particular advertising practice was unexpected

文章：

Line    Women’s grassroots activism and their vision
  of a new civic consciousness lay at the heart of
  social reform in the United States throughout the
  Progressive Era, the period between the depression
(5) of 1893 and America’s entry into the Second
  World War. Though largely disenfranchised except
  for school elections, white middle-class women
  reformers won a variety of victories, notably in
  the improvement of working conditions, especially
(10) for women and children. Ironically, though,
  child labor legislation pitted women of different
  classes against one another. To the reformers,
  child labor and industrial home work were equally
  inhumane practices that should be outlawed, but,
(15) as a number of women historians have recently
  observed, working-class mothers did not always
  share this view. Given the precarious finances of
  working-class families and the necessity of pooling
  the wages of as many family members as possible,
(20) working-class families viewed the passage and
  enforcement of stringent child labor statutes as a
  personal economic disaster and made strenuous
  efforts to circumvent child labor laws. Yet
  reformers rarely understood this resistance in terms
(25) of the desperate economic situation of working-
  class families, interpreting it instead as evidence
  of poor parenting. This is not to dispute women
  reformers’ perception of child labor as a terribly
  exploitative practice, but their understanding of
(30) child labor and their legislative solutions for ending
  it failed to take account of the economic needs of
  working-class families.

The author of the passage mentions the observations of women historians (lines 15–17) most probably in order to

选项:

A、provide support for an assertion made in the preceding sentence (lines 10–12)
B、raise a question that is answered in the last sentence of the passage (lines 27–32)
C、introduce an opinion that challenges a statement made in the first sentence of the passage
D、offer an alternative view to the one attributed in the passage to working-class mothers
E、point out a contradiction inherent in the traditional view of child labor reform as it is presented in the passage

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?
