题目:

A provincial government plans to raise the gasoline tax to give people an incentive to drive less, reducing traffic congestion in the long term. However, skeptics point out that most people in the province live in areas where cars are the only viable transportation to jobs and stores and therefore cannot greatly change their driving habits in response to higher gasoline prices.

In light of the skeptics’ objection, which of the following, if true, would most logically support the prediction that the government’s plan will achieve its goal of reducing traffic congestion?

选项:

A、The revenue from the tax will be used to make public transportation a viable means of transportation to jobs and stores for far more people.
B、The tax will encourage many residents to switch to more fuel-efficient cars, reducing air pollution and other problems.
C、Because gasoline has been underpriced for decades, the province has many neighborhoods where cars are the only viable means of transportation.
D、Most residents who cannot greatly change their driving habits could compensate for high gasoline prices by reducing other expenses.
E、Traffic congestion is an especially serious problem for people for whom cars are the only viable means of transportation.

文章:

    Linda Kerber argued in the mid-1980's that after the American Revolution (1775-1783), an ideology of "republican motherhood" resulted in a surge of educational opportunities for women in the United States. Kerber maintained that the leaders of the new nation wanted women to be educated in order to raise politically virtuous sons. A virtuous citizenry was considered essential to the success of the country's republican form of government; virtue was to be instilled not only by churches and schools, but by families, where the mother's role was crucial. Thus, according to Kerber, motherhood became pivotal to the fate of the republic, providing justification for an unprecedented attention to female education.

    Introduction of the republican motherhood thesis dramatically changed historiography. Prior to Kerber's work, educational historians barely mentioned women and girls; Thomas Woody's 1929 work is the notable exception. Examining newspaper advertisements for academies. Woody found that educational opportunities increased for both girls and boys around 1750. pointing to "An Essay on Woman" (1753) as reflecting a shirt in view. Woody also claimed that practical education for females had many advocates before the Revolution, Woody's evidence challenges the notion that the Revgolution changed attiludes regarding female education, although it may have accelerated earlier trends. Historians' reliance on Kerber's "republican mother hood" thesis may have obscured the presence of these trends, making it difficult to determine to what extent the Revolution really changed women's lives.

题目:

According to the passage, Kerber main-tained that which of the following led to an increase in educational opportunities for women in the United States after the american revolution?

选项:

A、An unprecedented demand by women for greater educational opportunities in the decades following the Revolution
B、A new political ideology calling for equality of opportunity between women and men in all aspects of life
C、A belief that the American educational system could be reformed only if women participated more fully in that system
D、A belief that women needed to be educated if they were to contribute to the success of the nation's new form of government.
E、A recognition that women needed to be educated if they were to take an active role in the nation's schools and churches.

题目:

Male bowerbirds construct elaborately decorated nests, or bowers. Basing their judgment on the fact that different local populations of bowerbirds of the same species build bowers that exhibit different building and decorative styles, researchers have concluded that the bowerbirds' building styles are a culturally acquired, rather than a genetically transmitted, trait.

Which of the following, if true, would most strengthen the conclusion drawn by the researchers?

选项:

A、There are more common characteristics than there are differences among the bower-building styles of the local bowerbird population that has been studied most extensively.
B、Young male bowerbirds are inept at bower-building and apparently spend years watching their elders before becoming accomplished in the local bower style.
C、The bowers of one species of bowerbird lack the towers and ornamentation characteristic of the bowers of most other species of bowerbird.
D、Bowerbirds are found only in New Guinea and Australia, where local populations of the birds apparently seldom have contact with one another.
E、It is well known that the song dialects of some songbirds are learned rather than transmitted genetically.

文章:

Line Arboria is floundering in the global marketplace,
incurring devastating losses in market position and
profits. The problem is not Arboria's products, but
Arboria's trade policy. Arboria faces the prospect
(5) of continuing economic loss until Arborian business
and political leaders recognize the fundamental
differences between Arborian and foreign economic
systems. Today the key trade issue is not free trade
versus protectionism but diminishing trade versus
(10) expanding trade.
Arboria is operating with an obsolete trade policy,
an artifact of the mid-1940s when Arboria and
Whorfland dominated the global economy, tariffs
were the principal obstacle to trade, and Arborian
(15) supremacy was uncontested in virtually all industries.
In the intervening decades, economic circumstances
have shifted radically. Arborian trade policy has not.
Today, Arboria's trade policy seems paralyzed
by the relentless conflict between proponents of
(20) “free” and “fair” trade. The free traders argue that
Arborian markets should be open, and the movement
of goods and services across national borders
unrestrained. The fair traders assert that access to
Arborian markets should be restricted until Arborian
(25) businesses are granted equal access to foreign
markets. They contend that free trade is impossible
while other nations erect barriers to Arborian exports.
Both are correct: fair trade requires equal access
and equal access leads to free trade. But both sides
(30) base their positions on the same two outdated
premises:
1. Global commerce is conducted under the terms of
the General Agreement on Tariffs and Trade (GATT)
and dominated by Arboria and similar economic
(35) systems abroad.
2. Multilateral negotiations are the most effective way
to resolve pressing trade issues.
Both assumptions are wrong. The 40-year-old GATT
now covers less than 7 percent of global commerce.
(40) World trade is no longer dominated by the free-
trade economies; nearly 75 percent is conducted
by economic systems operating with principles at
odds with those of Arboria. Forging a multilateral
trade policy consensus among so many diverse
(45) economic systems has become virtually impossible.
And while multilateral talks drag on, Arboria misses
opportunities for trade expansion.

题目:

The author asserts which of the following about Arboria's trade policy?

选项:

A、A dramatic revision of Arboria's trade policy will be necessary unless Arborian manufacturers improve the quality of their goods.
B、The most crucial issue facing Arborian trade policymakers is that of free trade versus protectionism.
C、Arboria's current trade policy was essentially developed during the 1940s and has changed little since that time.
D、Arboria's trade policy is widely emulated throughout the world, to the extent that most international commerce is modeled on Arboria's principles.
E、Arboria's trade policy has evolved gradually over the last eighty years, constantly readjusting itself in response to shifts in global commerce.

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?
