文章:

In a new book about the antiparty feeling of the early political leaders of the United States, Ralph Ketcham argues that the first six Presidents differed decisively from later Presidents because the first six held values inherited from the classical humanist tradition of eighteenth-century England. In this view, government was designed not to satisfy the private desires of the people but to make them better citizens; this tradition stressed the disinterested devotion of political leaders to the public good.  Justice, wisdom, and courage were more important qualities in a leader than the ability to organize voters and win elections.  Indeed, leaders were supposed to be called to office rather than to run for office.  And if they took up the burdens of public office with a sense of duty, leaders also believed that such offices were naturally their due because of their social preeminence or their contributions to the country.  Given this classical conception of leadership, it is not surprising that the first six Presidents condemned political parties.  Parties were partial by definition, self-interested, and therefore serving something other than the transcendent public good.
 
Even during the first presidency (Washington's), however, the classical conception of virtuous leadership was being undermined by commercial forces that had been gathering since at least the beginning of the eighteenth century.  Commerce--its profit-making, its self-interestedness, its individualism--became the enemy of these classical ideals.  Although Ketcham does not picture the struggle in quite this way, he does rightly see Jackson's tenure (the seventh presidency) as the culmination of the acceptance of party, commerce, and individualism.  For the Jacksonians, nonpartisanship lost its relevance, and under the direction of Van Buren, party gained a new legitimacy.  The classical ideals of the first six Presidents became identified with a privileged aristocracy, an aristocracy that had to be overcome in order to allow competition between opposing political interests.  Ketcham is so strongly committed to justifying the classical ideals, however, that he underestimates the advantages of their decline.  For example, the classical conception of leadership was incompatible with our modern notion of the freedoms of speech and press, freedoms intimately associated with the legitimacy of opposing political parties.

题目:

Which of the following, if true, provides the LEAST support for the author's argument about commerce and political parties during Jackson's presidency?

选项:

A、Many supporters of Jackson resisted the commercialization that could result from participation in a national economy.
B、Protest against the corrupt and partisan nature of political parties in the United States subsided during Jackson's presidency.
C、During Jackson's presidency the use of money became more common than bartering of goods and services.
D、More northerners than southerners supported Jackson because southerners were opposed to the development of a commercial economy.
E、Andrew Jackson did not feel as strongly committed to the classical ideals of leadership as George Washington had felt.

题目:

Economist:  On average, the emergency treatment for an elderly person for injuries resulting from a fall costs $11,000.  A new therapeutic program can significantly reduce an elderly person's chances of falling.  Though obviously desirable for many reasons, this treatment program will cost $12,500 and thus cannot be justified.
 
Which of the following, if true, most seriously undermines the conclusion of the argument?

选项:

A、Among elderly people who had followed the program for only a few months, the number of serious falls reported was higher than it was for people who had followed the program for its recommended minimum length of one year.
B、Falls resulting in serious injuries are less common among elderly people living in nursing homes than they are among elderly people who live alone at home.
C、A frequent result of injuries sustained in falls is long-term pain, medication for which is not counted among the average per-person costs of emergency treatment for elderly people's injuries from such falls.
D、The new therapeutic program focuses on therapies other than medication, since overmedication can cause disorientation and hence increase the likelihood that an elderly person will have a serious fall.
E、A significant portion of the cost of the new therapeutic program is represented by regular visits by health care professionals, the costs of which tend to increase more rapidly than do those of other elements of the program.

题目:

The recent decline in the value of the dollar was triggered by a prediction of slower economic growth in the coming year.  But that prediction would not have adversely affected the dollar had it not been for the government's huge budget deficit, which must therefore be decreased to prevent future currency declines.

选项:

A、The government has made little attempt to reduce the budget deficit.
B、The budget deficit has not caused a slowdown in economic growth.
C、The value of the dollar declined several times in the year prior to the recent prediction of slower economic growth.
D、Before there was a large budget deficit, predictions of slower economic growth frequently caused declines in the dollar's value.
E、When there is a large budget deficit, other events in addition to predictions of slower economic growth sometimes trigger declines in currency value.

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?
