In Arumville, among those young children with elevated levels of lead in their blood, few live in houses containing lead-based paint, but many live in areas where vehicular traffic is heavy. These children's elevated blood-lead levels probably result from lead added to gasoline, since, although gasoline sold in and around Arumville has been lead-free since 1990, lead from vehicle exhaust remains in the soil for many years.
Which of the following, if true, most strengthens the argument?
A. Sales of lead-based paint for use in homes was banned in Arumville in 1977.
B. Vehicle traffic in most residential areas of Arumville is heavier today than it was twenty years ago.
C. Some lead in the soil comes from deteriorating lead-based paint on the exteriors of buildings. D. In Arumville, children's blood-lead levels typically rise during the warm summer months when children frequently play outdoors but not in the winter when children spend more time indoors.
E. If improperly carried out, the removal of lead-based paint from older houses can significantly increase the risk that children living in such houses will ingest lead dust.
在A这个地方，孩子们的血铅含量在上升，但是在房间里面的涂料很少含铅，但是附近的交通拥挤，孩子们的血铅含量升高可能是因为汽油里面的铅。虽然从1990年开始A就要求使用无铅汽油，但是汽车尾气排放出来的铅会在土壤里保留很长时间。问加强？ D选项说在A地方，孩子们的普遍血铅含量在暖和的夏天比在冬天多，因为夏天经常在户外，所以证明孩子们的铅是吸收了含铅的尾气或者土壤里面的残留

Technological improvements and reduced equipment costs have made converting solar energy directly into electricity far more cost-efficient in the last decade. However, the threshold of economic viability for solar power (that is, the price per barrel to which oil would have to rise in order for new solar power plants to be more economical than new oil-fired power plants) is unchanged at thirty-five dollars.
Which of the following, if true, does most to help explain why the increased cost-efficiency of solar power has not decreased its threshold of economic viability? A. The cost of oil has fallen dramatically.
B. The reduction in the cost of solar-power equipment has occurred despite increased raw material costs for that equipment.
C. Technological changes have increased the efficiency of oil-fired power plants.
D. Most electricity is generated by coal-fired or nuclear, rather than oil-fired, power plants. E. When the price of oil increases, reserves of oil not previously worth exploiting become economically viable.
技术的进步，使得太阳能转换为电能变得更加的经济， 但是使用可行性准入门槛依旧是35元。问为什么提高了成本效率，为什么没有减低门槛。Ｃ选项说技术的进步也改变了ｏｉｌ－ｆｉｒｅｄ公司的效率。注意括号里面的解释，括号里面的大致的意思是说太阳能和石油成正相关，如果石油技术进步，那么太阳能转换技术也进步了，所以总体比率不变，所以门槛还是没降低

Many people suffer an allergic reaction to sulfites, including those that are commonly added to
wine as preservatives. However, since there are several winemakers producing wine to which no sulfites are added, those who would like to drink wine but are allergic to sulfites can drink these wines without risking an allergic reaction to sulfites.
Which of the following, if true, most seriously weakens the argument? A. Sulfites occur naturally in most wine.
B. The sulfites that can produce an allergic reaction are also commonly found in beverages other than wine.
C. Wines without added sulfites tend to be at least moderately expensive.
D. Apart from sulfites, there are other substances commonly present in wine that can trigger allergic reactions.
E. Wine without added sulfites sometimes becomes undrinkable even before the wine is sold to consumers.

The general availability of high-quality electronic scanners and color printers for computers has made the counterfeiting of checks much easier. In order to deter such counterfeiting, several banks plan to issue to their corporate customers checks that contain dots too small to be accurately duplicated by any electronic scanner currently available; when such checks are scanned and printed, the dots seem to blend together in such a way that the word “VOID” appears on the check.
A questionable assumption of the plan is that
A. in the territory served by the banks the proportion of counterfeit checks that are made using electronic scanners has remained approximately constant over the past few years
B. most counterfeiters who use electronic scanners counterfeit checks only for relatively large amounts of money
C. the smallest dots on the proposed checks cannot be distinguished visually except under strong magnification
D. most corporations served by these banks will not have to pay more for the new checks than for traditional checks
E. the size of the smallest dots that generally available electronic scanners are able to reproduce accurately will not decrease significantly in the near future
高质量的电子扫描机器和彩色打印机使得制造假的支票更加的容易，为了防止假造，一些银行开始计划给客户使用一种含有非常小点的支票，这种支票的小点太小以至于不能被现在的扫描仪扫描，当扫描的时候，支票上会出现“ＶＯＩＤ”的字样。问ｄｅｐｅｎｄ？ Ｅ选项说那些扫描仪不会在短时间内可以伪造出那么小的点。说明小点有用。

Every fall Croton's jays migrate south. The jays always join flocks of migrating crookbeaks with which they share the same summer and winter territories. If a jay becomes separated from the crookbeaks it is accompanying, it wanders until it comes across another flock of crookbeaks. Clearly, therefore, Croton's jays lack the navigational ability to find their way south on their own.
Which of the following, if true, most strengthens the argument above?
A. Croton's jays lay their eggs in the nests of crookbeaks, which breed upon completing their southern migration.
B. The three species most closely related to crookbeaks do not migrate at all.
C. In the spring, Croton's jays migrate north in the company of Tattersall warblers.
D. Species other than Croton's jays occasionally accompany flocks of migrating crookbeaks. E. In the spring, crookbeaks migrate north before Croton's jays do.

Junior biomedical researchers have long assumed that their hirings and promotions depend significantly on the amount of their published work. People responsible for making hiring and promotion decisions in the biomedical research field, however, are influenced much more by the overall impact that a candidate's scientific publications have on his or her field than by the number of those publications.
The information above, if accurate, argues most strongly against which of the following claims? A. Even biomedical researchers who are just beginning their careers are expected already to have published articles of major significance to the field.
B. Contributions to the field of biomedical research are generally considered to be significant only if the work is published.
C. The potential scientific importance of not-yet-published work is sometimes taken into account in decisions regarding the hiring or promotion of biomedical researchers.
D. People responsible for hiring or promoting biomedical researchers can reasonably be
expected to make a fair assessment of the overall impact of a candidate's publications on his or her field.
E. Biomedical researchers can substantially increase their chances of promotion by fragmenting their research findings so that they are published in several journals instead of one.
资浅的生物医学家总是把他们获得职位和升迁归结于发表文章的数量，但是实际上获得职位的和升迁的原因更多在于发表的作品的影响力而不是数量，问削弱？ Ｅ选项说生物医学家，可以增加升迁机会通过把它们的作品发表在不同的杂志上面，而不是同一个。所以说明还是数量决定升迁。

Wolves generally avoid human settlements. For this reason, domestic sheep, though
essentially easy prey for wolves, are not usually attacked by them. In Hylantia prior to 1910, farmers nevertheless lost considerable numbers of sheep to wolves each year. Attributing this to the large number of wolves, in 1910 the government began offering rewards to hunters for killing wolves. From 1910 to 1915, large numbers of wolves were killed. Yet wolf attacks on sheep increased significantly.
Which of the following, if true, most helps to explain the increase in wolf attacks on sheep? A. Populations of deer and other wild animals that wolves typically prey on increased significantly in numbers from 1910 to 1915.
B. Prior to 1910, there were no legal restrictions in Hylantia on the hunting of wolves. C. After 1910 hunters shot and wounded a substantial number of wolves, thereby greatly diminishing these wolves' ability to prey on wild animals.
D. Domestic sheep are significantly less able than most wild animals to defend themselves against wolf attacks.
E. The systematic hunting of wolves encouraged by the program drove many wolves in Hylantia to migrate to remote mountain areas uninhabited by humans.
狼总是避免进入人类的聚居地，因而，家养羊很少被袭击。但是１９１０年前，Ｈ地方的人民还是丢了很多羊，把原因归结于狼，所以制定奖金给猎杀狼的猎手。１９１０－１９１５年很多狼都被杀了，但是袭击羊的情况更加的多了。问为什么？Ｃ选项说经过大量猎杀狼之后，降低了狼们猎杀野生动物的能力，意思是狼们猎不到别的，只能吃羊

The number of applications for teaching positions in Newtown's public schools was 5.7 percent lower in 1993 than in 1985 and 5.9 percent lower in 1994 than in 1985. Despite a steadily growing student population and an increasing number of teacher resignations, however,
Newtown does not face a teacher shortage in the late 1990's.
Which of the following, if true, would contribute most to an explanation of the apparent discrepancy above?
A. Many of Newtown's public school students do not graduate from high school.
B. New housing developments planned for Newtown are slated for occupancy in 1997 and are expected to increase the number of elementary school students in Newtown's public schools by 12 percent.
C. The Newtown school board does not contemplate increasing the ratio of students to teachers in the 1990's.
D. Teachers' colleges in and near Newtown produced fewer graduates in 1994 than in 1993. E. In 1993 Newtown's public schools received 40 percent more applications for teaching positions than there were positions available.

The growing popularity of computer-based activities was widely predicted to result in a corresponding decline in television viewing. Recent studies have found that, in the United States, people who own computers watch, on average, significantly less television than people who do not own computers. In itself, however, this finding does very little to show that computer use tends to reduce television viewing time, since __________. A. many people who watch little or no television do not own a computer
B. even though most computer owners in the United States watch significantly less television than the national average, some computer owners watch far more television than the national average
C. computer owners in the United States predominantly belong to demographic groups that have long been known to spend less time watching television than the population as a whole does
D. many computer owners in the United States have enough leisure time that spending significant amounts of time on the computer still leaves ample time for watching television E. many people use their computers primarily for tasks such as correspondence that can be done more rapidly on the computer, and doing so leaves more leisure time for watching television

X: In order to reduce the amount of plastic in landfills, legislatures should impose a ban on the use of plastics for packaging goods.
Y: Impossible! Plastic packaging is necessary for public safety. Consumers will lose all of the safety features that plastic offers, chiefly tamper-resistant closures and shatterproof bottles.
Which of the following best describes the weak point in Y's response to X's proposal?
A. Y ignores the possibility that packaging goods in materials other than plastic might provide the same safety features that packaging in plastic offers.
B. The economic disadvantages of using plastics as a means of packaging goods are not taken into consideration.
C. Y attempts to shift the blame for the large amount of plastic in landfills from the users of plastic packaging to the legislators.
D. Y does not consider the concern of some manufacturers that safety features spoil package
appearances.
E. Y wrongly assumes that X defends the interests of the manufacturers rather than the interests of the consumers.
为了减少在垃圾场的塑料的数量，立法决定禁止使用塑料包装食物。但是这种方式不可能，因为塑料包装对于公众是安全的，消费者将失去塑料包装带来的好处。问削弱Ｙ的观点。Ａ选项在说Ｙ认为塑料对于包装的必要性，曲解了Ｘ的意图。（ＰＳ我也不是很明白）

In a certain wildlife park, park rangers are able to track the movements of many rhinoceroses because those animals wear radio collars. When, as often happens, a collar slips off, it is put back on. Putting a collar on a rhinoceros involves immobilizing the animal by shooting it with a tranquilizer dart. Female rhinoceroses that have been frequently recollared have
significantly lower fertility rates than uncollared females. Probably, therefore, some substance in the tranquilizer inhibits fertility.
Which of the following is an assumption on which the argument depends?
A. The dose of tranquilizer delivered by a tranquilizer dart is large enough to give the rangers putting collars on rhinoceroses a generous margin of safety.
B. The fertility rate of uncollared female rhinoceroses in the park has been increasing in the past few decades.
C. Any stress that female rhinoceroses may suffer as a result of being immobilized and handled has little or no negative effect on their fertility.
D. The male rhinoceroses in the wildlife park do not lose their collars as often as the park’s female rhinoceroses do.
E. The tranquilizer used in immobilizing rhinoceroses is the same as the tranquilizer used in working with other large mammals.

Editor: Articles in Gardening Magazine often spur sales of the plants they describe,
particularly among people new to gardening. Accordingly, we will no longer publish articles or accept advertisements praising the beauty of rare wildflowers. Most such plants sold to
gardeners have been difficult to propagate under cultivation, so plant sellers often collect them in the wild. Our new policy is part of our efforts to halt this yearly plundering of our native plant populations.
Which of the following, if true, casts the most doubt on the wisdom of the magazine's new policy as a way of pursuing the intended effect?
A. When people new to gardening buy plants, they often fail to take adequate care of the plants that they buy and become discouraged from buying those varieties again.
B. Plant sellers who sell rare wildflowers have no reasonably inexpensive alternative way to offer their wares directly to new gardeners.
C. The demand for rare wildflowers rarely exceeds the number of such plants that can be collected in the wild by plant sellers.
D. The propagation of rare wildflowers often depends on the plants' interaction with other organisms in their environment, such as plants that create suitable soil conditions or insects and birds that disperse seeds.
E. Revenues from sales of plants collected in the wild are supporting the discovery of new low-cost techniques enabling rare wildflowers to be readily propagated in nurseries.
