题目:

Although most smoking-related illnesses are caused by inhaling the tar in tobacco smoke, it is addiction to nicotine that prevents most smokers from quitting.  In an effort to decrease the incidence of smoking-related illnesses, lawmakers in Sandonia plan to reduce the average quantity of nicotine per cigarette by half over the next five years.  Unfortunately, smokers who are already addicted to nicotine tend to react to such reductions by smoking correspondingly more cigarettes.

The information above most strongly supports which of the following predictions about the effects of implementing the Sandonian government’s plan?

选项:

A、The average quantity of tar inhaled by Sandonian smokers who are currently addicted to nicotine will probably not decrease during the next five years.
B、Sandonian smokers who are not already addicted to nicotine will probably also begin to smoke more cigarettes during the next five years than they had previously.
C、The annual number of Sandonian smokers developing smoking-related illnesses will probably decrease during the next five years.
D、The proportion of Sandonians attempting to quit smoking who succeed in that attempt will probably decrease during the next five years.
E、The number of Sandonians who quit smoking during the next five years will probably exceed the number who quit during the last five years.

题目:

In Wareland last year, 16 percent of licensed drivers under 21 and 11 percent of drivers ages 21–24 were in serious accidents. By contrast, only 3 percent of licensed drivers 65 and older were involved in serious accidents. These figures clearly show that the greater experience and developed habits of caution possessed by drivers in the 65-and-older group make them far safer behind the wheel than the younger drivers are.

Which of the following is an assumption on which the argument depends?

选项:

A、Drivers 65 and older do not, on average, drive very many fewer miles per year than drivers 24 and younger.
B、Drivers 65 and older do not constitute a significantly larger percentage of licensed drivers in Wareland than drivers ages 18–24 do.
C、Drivers 65 and older are less likely than are drivers 24 and younger to drive during weather conditions that greatly increase the risk of accidents.
D、The difference between the accident rate of drivers under 21 and of those ages 21–24 is attributable to the greater driving experience of those in the older group.
E、There is no age bracket for which the accident rate is lower than it is for licensed drivers 65 and older.

题目:

Rabbits were introduced to Numa Island in the nineteenth century.  Overgrazing by the enormous population of rabbits now menaces the island's agriculture.  The government proposes to reduce the population by using a virus that has caused devastating epidemics in rabbit populations elsewhere.  There is, however, a chance that the virus will infect the bilby, an endangered native marsupial.  The government's plan, therefore, may serve the interests of agriculture but will clearly increase the threat to native wildlife.
 
Which of the following, if true, most seriously weakens the argument?

选项:

A、There is less chance that the virus will infect domestic animals on Numa than that it will infect bilbies.
B、There are no species of animals on the island that prey on the rabbits.
C、Overgrazing by rabbits endangers many of the plants on which bilbies feed.
D、The virus that the government proposes to use has been successfully used elsewhere to control populations of rabbits.
E、There is no alternative means of reducing the rabbit population that would involve no threat to the bilby.

文章:

    When the history of women began to receive focused attention in the 1970', Eleanor Roosevelt was one of a handful of female Americans who were well known to both historians and the general public. Despite the evidence that she had been important in socialreform circles before her husband was elected President and that she continued to advocate different causes than he did, she held a place in the public imagination largely because she was the wife of a particularly influential President. Her own activities were seen as preparing the way for her husband's election or as a complement to his programs. Even Joseph Lash's two volumes of Sympathetic biography, Eleanor and Franklin (1971) and Eleanor: The Years Alone (1972), reflected this assumption.

    Lash's biography revealed a Complicated woman who sought Through political activity both to flee inner misery and to promote causes in which she passionately believed. However, she still appeared to be an idiosyncratic figure, somehow self-generated not amenable to any generalized explanation. She emerged from the biography as a mother to the entire nation, or as a busybody. but hardly as a social type, a figure comprehensible in terms of broader social developments.

    But more recent work on the feminism of the post-suffrage years (following 1920) allows us to see Roosevelt in a different light and to bring her life into a more richly detailed context. Lois Scharf's Eleanor Roosevelt, written In 1987, depicts a generation of Privileged women, born in the late Nineteenth century and maturing in the twentieth, who made the transition from old patterns of female association to new ones. Their views and their lives were full Of contradictions. They maintained female social networks but began to integrate women into mainstream politics; they demanded equal treatment but also argued that women's maternal responsibilities made them both wards and representatives of the public interest. Thanks to Scharf and others, Roosevelt's activities—for example, her support both for labor laws protecting women and for appointments of women to high public office—have become intelligible in terms of this social context rather than as the idiosyncratic career of a famous man's wife.

题目:

The author cites which of the following as evidence against the public view of Eleanor Roosevelt held in the 1970's?

选项:

A、She had been born into a wealthy family.
B、Her political career predated the adoption of women's suffrage.
C、She continued her career in politics even After her husband's death.
D、She was one of a few female historical Figures who were well known to historians By the 1970's.
E、Her activism predated her husband's presidency and her projects differed from his.

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.
