文章：

Line         When Jamaican-born social activist Marcus
  Garvey came to the United States in 1916, he
  arrived at precisely the right historical moment.
  What made the moment right was the return of
(5) African American soldiers from the First World War
  in 1918, which created an ideal constituency for
  someone with Garvey’s message of unity, pride,
  and improved conditions for African American
  communities.
(10)      Hoping to participate in the traditional American
  ethos of individual success, many African American
  people entered the armed forces with enthusiasm,
  only to find themselves segregated from white
  troops and subjected to numerous indignities. They
(15) returned to a United States that was as segregated
  as it had been before the war. Considering similar
  experiences, anthropologist Anthony F. C. Wallace
  has argued that when a perceptible gap arises
  between a culture’s expectations and the reality of
(20) that culture, the resulting tension can inspire a
  revitalization movement: an organized, conscious
  effort to construct a culture that fulfills longstanding
  expectations.
       Some scholars have argued that Garvey created
(25) the consciousness from which he built, in the 1920s,
  the largest revitalization movement in
  African American history. But such an argument only
  tends to obscure the consciousness of
  identity, strength, and sense of history that already
(30) existed in the African American community. Garvey
  did not create this consciousness; rather, he gave
  this consciousness its political expression.


题目：

According to the passage, which of the following contributed to Marcus Garvey’s success?

选项:

A、He introduced cultural and historical consciousness to the African American community.
B、He believed enthusiastically in the traditional American success ethos.
C、His audience had already formed a consciousness that made it receptive to his message.
D、His message appealed to critics of African American support for United States military involvement in the First World War.
E、He supported the movement to protest segregation that had emerged prior to his arrival in the United States.

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.
