文章：

Line         It is an odd but indisputable fact that the
  seventeenth-century English women who are
  generally regarded as among the forerunners of
  modern feminism are almost all identified with the
(5) Royalist side in the conflict between Royalists and
  Parliamentarians known as the English Civil Wars.
  Since Royalist ideology is often associated with the
  radical patriarchalism of seventeenth-century
  political theorist Robert Filmer—a patriarchalism
(10) that equates family and kingdom and asserts the
  divinely ordained absolute power of the king and,
  by analogy, of the male head of the household—
  historians have been understandably puzzled by the
  fact that Royalist women wrote the earliest
(15) extended criticisms of the absolute subordination
  of women in marriage and the earliest systematic
  assertions of women’s rational and moral equality
  with men. Some historians have questioned the
  facile equation of Royalist ideology with Filmerian
(20) patriarchalism; and indeed, there may have been
  no consistent differences between Royalists and
  Parliamentarians on issues of family organization
  and women’s political rights, but in that case one
  would expect early feminists to be equally divided
(25) between the two sides.
       Catherine Gallagher argues that Royalism
  engendered feminism because the ideology of
  absolute monarchy provided a transition to an
  ideology of the absolute self. She cites the example
(30) of the notoriously eccentric author Margaret
  Cavendish (1626–1673), duchess of Newcastle.
  Cavendish claimed to be as ambitious as any
  woman could be, but knowing that as a woman she
  was excluded from the pursuit of power in the real
(35) world, she resolved to be mistress of her own
  world, the “immaterial world” that any person can
  create within her own mind—and, as a writer, on
  paper. In proclaiming what she called her
  “singularity,” Cavendish insisted that she was a
(40) self-sufficient being within her mental empire, the
  center of her own subjective universe rather than a
  satellite orbiting a dominant male planet. In
  justifying this absolute singularity, Cavendish
  repeatedly invoked the model of the absolute
(45) monarch, a figure that became a metaphor for the
  self-enclosed, autonomous nature of the individual
  person. Cavendish’s successors among early
  feminists retained her notion of woman’s sovereign
  self, but they also sought to break free from the
(50) complete political and social isolation that her
  absolute singularity entailed.

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?
