题目：

Enforcement of local speed limits through police monitoring has proven unsuccessful in the town of Ardane. In many nearby towns, speed humps (raised areas of pavement placed across residential streets, about 300 feet apart) have reduced traffic speeds on residential streets by 20 to 25 percent. In order to reduce traffic speed and thereby enhance safety in residential neighborhoods, Ardane's transportation commission plans to install multiple speed humps in those neighborhoods.

Which of the following, if true, identifies a potentially serious drawback to the plan for installing speed humps in Ardane?

选项:

A、On residential streets without speed humps, many vehicles travel at speeds more than 25 percent above the posted speed limit.
B、Because of their high weight, emergency vehicles such as fire trucks and ambulances must slow almost to a stop at speed humps.
C、The residential speed limit in Ardane is higher than that of the nearby towns where speed humps were installed.
D、Motorists who are not familiar with the streets in Ardane's residential districts would be likely to encounter the speed humps unawares unless warned by signs and painted indicators.
E、Bicyclists generally prefer that speed humps be constructed so as to leave a space on the side of the road where bicycles can travel without going over the humps.

B

文章：

The United States government has a long-standing policy of using federal funds to keep small business viable.  The Small Business Act of 1953 authorized the Small Business Administration (SBA) to enter into contracts with government agencies having procurement powers and to arrange for fulfillment of these contracts by awarding subcontracts to small businesses.  In the mid-1960's, during the war on poverty years, Congress hoped to encourage minority entrepreneurs by directing such funding to minority businesses.  At first this funding was directed toward minority entrepreneurs with very low incomes.  A 1967 amendment to the Economic Opportunity Act directed the SBA to pay special attention to minority-owned businesses located in urban or rural areas characterized by high proportions of unemployed or low-income individuals.  Since then, the answer given to the fundamental question of who the recipients should be--the most economically disadvantaged or those with the best prospects for business success--has changed, and the social goals of the programs have shifted, resulting in policy changes.
 
The first shift occurred during the early 1970's.  While the goal of assisting the economically disadvantaged entrepreneur remained, a new goal emerged:  to remedy the effects of past discrimination.  In fact, in 1970 the SBA explicitly stated that their main goal was to increase the number of minority-owned businesses.  At the time, minorities constituted seventeen percent of the nation's population, but only four percent of the nation's self-employed.  This ownership gap was held to be the result of past discrimination.  Increasing the number of minority-owned firms was seen as a way to remedy this problem.  In that context, providing funding to minority entrepreneurs in middle- and high-income brackets seemed justified.
 
In the late 1970's, the goals of minority-business funding programs shifted again.  At the Minority Business Development Agency, for example, the goal of increasing numbers of minority-owned firms was supplanted by the goal of creating and assisting more minority-owned substantive firms with future growth potential.  Assisting manufacturers or wholesalers became far more important than assisting small service businesses.  Minority-business funding programs were now justified as instruments for economic development, particularly for creating jobs in minority communities of high unemployment.

题目：

It can be inferred that the "ownership gap" (see highlighted text) would be narrowed if which of the following were to occur?

选项:

A、Minority entrepreneurs received a percentage of government contracts equal to that received by nonminority entrepreneurs.
B、Middle- and high-income minority entrepreneurs gave more assistance to their low-income counterparts in the business community.
C、Minority entrepreneurs hired a percentage of minority employees equal to the percentage of minority residents in their own communities.
D、The percentage of self-employed minority persons rose to more than ten percent of all self-employed persons.
E、Seventeen percent of all persons employed in small businesses were self-employed.

D

文章：

    Why firms adhere to or deviate from their strategic plans is poorly understood. However, theory and limited research suggest that the process through which such plans emerge may play a part. In particular, top management decision-sharing consensus-oriented, team-based Decision -making-may increase the likelihood that firms will adhere to their plans, because those involved in the decision-making may be more committed to the chosen course of action, thereby increasing the likelihood that organizations will subsequently adhere to their plans.

    However, the relationship between top management decision-sharing and adherence to plans may be affected by a firm's strategic mission (its fundamental approach to increasing sales revenue and market share, and generating cash flow and short-term profits). At one end of the strategic mission continuum, "build" strategies are pursued when a firm desires to increase its market share and is willing to sacrifice short-term profits to do so. At the other end, "harvest" strategies are used when a firm is willing to sacrifice market share for short-term profitability and cash-flow maximization. Research and theory suggest that top management decision-sharing may have a more positive relationship with adherence to plans among firms with harvest strategies than among firms with build strategies. In a study of strategic practices in several largefirms, managers in harvest strategy scenarios were more able to adhere to their business plans. As one of the managers in the study explained it, this is partly because "[t] ypically all a manager has to do [when implementing a harvest strategy] is that which was done last year." Additionally, managers under harvest strategies may have fewer strategic options than do those under build strategies; it may therefore be easier to reach agreement on a particular course of action through decision-sharing, which will in turn tend to promote adherence to plans. Conversely, in a "build" strategy scenario, individual leader-ship, rather than decision-sharing, may promote adherence to plans. Build strategies-which typically require leaders with strong personal visions for a firm's future, rather than the negotiated compromise of the team-based decision-maybe most closely adhered to when implemented in the context of a clear strategic vision of an individual leader, rather than through the practice of decision-sharing.

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.

C

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?
