题目：

It is widely assumed that people need to engage in intellectual activities such as solving crossword puzzles or mathematics problems in order to maintain mental sharpness as they age. In fact, however, simply talking to other people—that is, participating in social interaction, which engages many mental and perceptual skills—suffices. Evidence to this effect comes from a study showing that the more social contact people report, the better their mental skills.

Which of the following, if true, most seriously weakens the force of the evidence cited?

选项:

A、As people grow older, they are often advised to keep exercising their physical and mental capacities in order to maintain or improve them.
B、Many medical conditions and treatments that adversely affect a person’s mental sharpness also tend to increase that person’s social isolation.
C、Many people are proficient both in social interactions and in solving mathematical problems.
D、The study did not itself collect data but analyzed data bearing on the issue from prior studies.
E、The tasks evaluating mental sharpness for which data were compiled by the study were more akin to mathematics problems than to conversation.

题目：

Kernland imposes a high tariff on the export of unprocessed cashew nuts in order to ensure that the nuts are sold to domestic processing plants.  If the tariff were lifted and unprocessed cashews were sold at world market prices, more farmers could profit by growing cashews.  However, since all the processing plants are in urban areas, removing the tariff would seriously hamper the government's effort to reduce urban unemployment over the next five years.
 
Which of the following, if true, most seriously weakens the argument?

选项:

A、Some of the by-products of processing cashews are used for manufacturing paints and plastics.
B、Other countries in which cashews are processed subsidize their processing plants.
C、More people in Kernland are engaged in farming cashews than in processing them.
D、Buying unprocessed cashews at lower than world market prices enables cashew processors in Kernland to sell processed nuts at competitive prices.
E、A lack of profitable crops is driving an increasing number of small farmers in Kernland off their land and into the cities.

E

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?
