题目：
People who do regular volunteer work tend to live longer, on average, than people who do not. It has been found that “doing good,” a category that certainly includes volunteer work, releases endorphins, the brain’s natural opiates, which induce in people a feeling of well-being. Clearly, there is a connection: Regular releases of endorphins must in some way help to extend people’s lives.
Which of the following, if true, most seriously undermines the force of the evidence given as support for the hypothesis that endorphins promote longevity?
Which of the following, if true, most seriously undermines the force of the evidence given as support for the hypothesis that endorphins promote longevity?
选项:
A、People who do regular volunteer work are only somewhat more likely than others to characterize the work they do for a living as “doing good.”
B、Although extremely high levels of endorphins could be harmful to health, such levels are never reached as a result of the natural release of endorphins.
C、There are many people who have done some volunteer work but who do not do such work regularly.
D、People tend not to become involved in regular volunteer work unless they are healthy and energetic to begin with.
E、Releases of endorphins are responsible for the sense of well-being experienced by many long-distance runners while running.

题目：
Music critic: Fewer and fewer musicians are studying classical music, decreasing the likelihood that those with real aptitude for such music will be performing it. Audiences who hear these performances will not appreciate classical music's greatness and will thus decamp to other genres. So to maintain classical music's current meager popularity, we must encourage more young musicians to enter the field.
Which of the following, if true, most weakens the music critic's reasoning?
选项:
A、
A. Musicians who choose to study classical music do so because they believe they have an aptitude for the music.
B、
B. Classical music's current meager popularity is attributable to the profusion of other genres of music available to listeners.
C、
C. Most people who appreciate classical music come to do so through old recordings rather than live performances.
D、
D. It is possible to enjoy the music in a particular genre even when it is performed by musicians who are not ideally suited for that genre.
E、
E. The continued popularity of a given genre of music depends in part on the audiences being able to understand why that genre attained its original popularity.

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?
