题目：

Economist: The most economically efficient way to reduce emissions of air pollutants is to tax them in proportion to the damage they are likely to cause. But in Country Y, many serious pollutants are untaxed and unregulated, and policy makers strongly oppose new taxes. Therefore, the best way to achieve a reduction in air pollutant emissions in Country Y would be to institute fixed upper limits on them.

Which of the following is an assumption of the economist’s argument?

选项:

A、Policy makers in Country Y oppose all new taxes equally strongly, regardless of any benefits they may provide.
B、Country Y’s air pollutant emissions would not fall significantly if they were taxed in proportion to the damage they are likely to cause.
C、Policy makers in Country Y strongly favor reductions in air pollutant emissions.
D、Country Y’s policy makers believe that air pollutant emissions should be reduced with maximum economic efficiency.
E、Policy makers in Country Y do not oppose setting fixed upper limits on air pollutant emissions as strongly as they oppose new taxes.

E

题目：

Humans get Lyme disease from infected ticks. Ticks get infected by feeding on animals with Lyme disease, but the ease of transmission from host animal to tick varies. With most species of host animal, transmission of Lyme disease to ticks is extremely rare, but white-footed mice are an exception, readily passing Lyme disease to ticks. And white-footed mouse populations greatly expand, becoming the main food source for ticks, in areas where biodiversity is in decline.

The information in the passage most strongly supports which of the following?

选项:

A、In areas where many humans are infected with Lyme disease, the proportion of ticks infected with Lyme disease is especially high.
B、Very few animals that live in areas where there are no white-footed mice are infected with Lyme disease.
C、Humans are less at risk of contracting Lyme disease in areas where biodiversity is high.
D、Ticks feed on white-footed mice only when other host species are not available to them.
E、The greater the biodiversity of an area, the more likely any given host animal in that area is to pass Lyme disease to ticks.

题目：

Proposed new safety rules for the Beach City airport would lengthen considerably the minimum time between takeoffs from the airport. In consequence, the airport would be able to accommodate 10 percent fewer flights than currently use the airport daily. The city’s operating budget depends heavily on taxes generated by tourist spending, and most of the tourists come by plane. Therefore, the proposed new safety rules, if adopted, will reduce the revenue available for the operating budget.

The argument depends on assuming which of the following?

选项:

A、There are no periods of the day during which the interval between flights taking off from the airport is significantly greater than the currently allowed minimum.
B、Few, if any, of the tourists who use the Beach City airport do so when their main destination is a neighboring community and not Beach City itself.
C、If the proposed safety rules are adopted, the reduction in tourist numbers will not result mainly from a reduction in the number of tourists who spend relatively little in Beach City.
D、Increasing the minimum time between takeoffs is the only way to achieve necessary safety improvements without a large expenditure by the city government on airport enhancements.
E、The response to the adoption of the new safety rules would not include an increase in the number of passengers per flight.

E

题目：

First-time computer buyers buying PXC home computers typically buy models that cost much less and have a smaller profit margin per computer than do PXC computers bought by people replacing their computers with more powerful models.  Last year PXC's profits from computer sales were substantially higher than the previous year, although about the same number of PXC computers were sold and the prices and profit margins for each computer model that PXC sells remained unchanged.
 
If the statements above are true, which of the following is most strongly supported by them?

选项:

A、PXC's competitors raised the prices on their computers last year, making PXC computers more attractive to first-time computer buyers.
B、The number of people buying PXC computers who also bought PXC computer-related products, such as printers, was larger last year than the previous year.
C、Among computer buyers who bought a PXC computer to replace their existing computer, the proportion who were replacing a computer made by a competitor of PXC was greater last year than the previous year.
D、The proportion of PXC computers bought by first-time computer buyers was smaller last year than the previous year.

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?
