题目：

For most people, the left half of the brain controls linguistic capabilities, but some people have their language centers in the right half.  When a language center of the brain is damaged, for example by a stroke, linguistic capabilities are impaired in some way.  Therefore, people who have suffered a serious stroke on the left side of the brain without suffering any such impairment must have their language centers in the right half.
 
Which of the following is an assumption on which the reasoning in the argument above depends?

选项:

A、No part of a person's brain that is damaged by a stroke ever recovers.
B、Impairment of linguistic capabilities does not occur in people who have not suffered any damage to any language center of the brain.
C、Strokes tend to impair linguistic capabilities more severely than does any other cause of damage to language centers in the brain.
D、If there are language centers on the left side of the brain, any serious stroke affecting that side of the brain damages at least one of them.
E、It is impossible to determine which side of the brain contains a person's language centers if the person has not suffered damage to either side of the brain.

D

题目：

Lyme disease is caused by a bacterium transmitted to humans by deer ticks.  Generally deer ticks pick up the bacterium while in the larval stage from feeding on infected white-footed mice.  However, certain other species on which the larvae feed do not harbor the bacterium.  Therefore, if the population of these other species were increased, the number of ticks acquiring the bacterium―and hence the number of people contracting Lyme disease—would likely decline.
 
Which of the following, if true, most strengthens the argument?癮

选项:

A、Ticks do not suffer any adverse consequences from carrying the bacterium that causes Lyme disease in humans.
B、There are no known cases of a human's contracting Lyme disease through contact with white-footed mice.
C、A deer tick feeds only once while in the larval stage.
D、A single host animal can be the source of bacteria for many tick larvae.
E、None of the other species on which deer tick larvae feed harbor other bacteria that ticks transmit to humans.

题目：

Because ethylene dibromide, a chemical used to fumigate grain, was blamed for the high rate of nerve damage suffered by people who work in grain-processing plants, many such plants switched to other chemical fumigants two years ago.  Since then, however, the percentage of workers at these plants who were newly diagnosed with nerve damage has not dropped significantly.  Therefore, either ethylene dibromide was wrongly blamed or else the new chemicals also cause nerve damage.
Which of the following is an assumption on which the argument depends?

选项:

A、If the new chemicals cause nerve damage, the nerve damage caused would be different from any nerve damage that ethylene dibromide may cause.
B、There are no chemical fumigants that are completely safe for workers in grain-processing plants.
C、If ethylene dibromide causes nerve damage, it does not take two years or longer for that damage to become detectable.
D、Workers at grain-processing plants typically continue to work there even after being diagnosed with nerve damage.
E、Workers at grain-processing plants that still use ethylene dibromide continue to have a high rate of nerve damage.

题目：

Editorial in Krenlandian Newspaper:
 
Krenland's steelmakers are losing domestic sales because of lower-priced imports, in many cases because foreign governments subsidize their steel industries in ways that are banned by international treaties.  But whatever the cause, the cost is ultimately going to be jobs in Krenland's steel industry.  Therefore, it would protect not only steel companies but also industrial employment in Krenland if our government took measures to reduce cheap steel imports.
 
Which of the following, if true, most seriously weakens the editorial's argument?

选项:

A、Because steel from Krenland is rarely competitive in international markets, only a very small portion of Krenlandian steelmakers' revenue comes from exports.
B、The international treaties that some governments are violating by giving subsidies to steelmakers do not specify any penalties for such violations.
C、For many Krenlandian manufacturers who face severe international competition in both domestic and export markets, steel constitutes a significant part of their raw material costs.
D、Because of advances in order-taking, shipping, and inventory systems, the cost of shipping steel from foreign producers to Krenland has fallen considerably in recent years.
E、Wages paid to workers in the steel industry in Krenland differ significantly from wages paid to workers in many of the countries that export steel to Krenland.

题目：

Fearing competition from stores that rent video games for home use, owners of stores that sell video games lobbied for protective legislation.  Citing as a precedent legislation that postpones home film rentals until one year after general release to theaters, the video sellers proposed as an equitable solution a plan that would postpone rental of any video game until it had been available for sale for one year.
 
Which of the following, if true, would support an objection by owners of video rental stores that the fairness of the proposed legislation is not supported by the precedent cited?

选项:

A、Although the daily rental fee for home use of films is generally the same as that for video games, the average rental period for a video game is longer than that for a film.
B、Film rentals for home use tend to particularly strong during the first year after a film has been made available for both sale and rental at video rental stores.
C、Most people are interested in playing only the latest video games and tend to find video games that have been available for over a year unappealing whether they have played them before or not, whereas films maintain their appeal far longer after their release.
D、People who rent video games tend to play them by themselves, whereas people who rent films invite friends and neighbors to watch.
E、A slight decline in revenues from films that have been recently released in theaters has been attributed to the growing market for rentals of films for home use.

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?

What was the dealer's approximate profit or loss as a percent of the dealer's initial cost for the 60 cameras?
