题目：

Press Secretary:  Our critics claim that the President's recent highway project cancellations demonstrate a vindictive desire to punish legislative districts controlled by opposition parties.  They offer as evidence the fact that 90 percent of the projects canceled were in such districts.  But all of the canceled projects had been identified as wasteful in a report written by respected nonpartisan auditors.  So the President's choice was clearly motivated by sound budgetary policy, not partisan politics.
 
Which of the following is an assumption on which the press secretary's argument depends?

选项:

A、Canceling highway projects was not the only way for the President to punish legislative districts controlled by opposition parties.
B、The scheduled highway projects identified as wasteful in the report were not mostly projects in districts controlled by the President's party.
C、The number of projects canceled was a significant proportion of all the highway projects that were to be undertaken by the government in the near future.
D、The highway projects canceled in districts controlled by the President's party were not generally more expensive than the projects canceled in districts controlled by opposition parties.
E、Reports by nonpartisan auditors are not generally regarded by the opposition parties as a source of objective assessments of government projects.

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?
