标题: 问两道逻辑题，望牛牛们帮忙 [打印本页] 作者: melody1101 时间: 2012-3-31 23:07 标题: 问两道逻辑题，望牛牛们帮忙 1、A beach has long had a dolphin feeding program where foods are given to dolphins several times a day; the dolphins get as much as half of their food each day there. While dolphins that first benefit from the program as adults are strong and long-lived, their offspring have a shorter life expectancy than offspring of dolphins that feed only in the wild 解释题 A. Many dolphines that feed at the beach with their offspring come to the beach only a few times a mouth. B. Adults dolphins that feed at the beach spend much less time teaching their offspring how to catch fish in the wild than do other adult dolphins. 选哪个呀亲们，答案是A，我觉得是B
2、Outbreaks of Oudayas Valley fever occur irregularly in North Africa, several years apart. When outbreak do occur, they kill hundreds of cattle. A livestock vaccine against the disease exists but is rarely used. It is too expensive for farmers to use routinely, and because it is ineffective untill two weeks after vaccination, administering it after an outbreak begins helps very little. Nonetheless, experts predict that use of the vaccine will increase significantly within the next few years.
解释题
A. When an outbreak of Oudayas Valley fever occurs, unaffected countries often refuse to import livrstock from the countries affected by the outbreak.
B. Recently published research has shown that certain identifiable climatic conditions are almost invariably followed, within three to six weeks, by an outbreak of Oudayas Valley fever. 答案是B，我觉得A对，快快答复小女子哈，谢谢各位啦！作者: 韩啸0508 时间: 2012-3-31 23:18
第一个 我也不明白，第二个的话， B 的关键在于 within three to six weeks， 这样 farmer就可以提前预防打vaccine了，（因为routinely太贵，而药要两周之后才有效）作者: melody1101 时间: 2012-3-31 23:25
我记得老师说过大众权威的观点做降格处理，而且B选项没说certain climatic conditions 对这件事会带来什么样的影响。作者: 韩啸0508 时间: 2012-3-31 23:38
fever会由不定的天气导致（即 certain climatic condition会诱发fever，但不一定，所以是预防，就像我们打疫苗一样），而 大众权威之所以被降格， 估计是要在assumption或是must be true这样的，只能从原文出发，没有新元素的情况下吧（抱歉不是很清楚您们老师的原话是怎样额）作者: melody1101 时间: 2012-4-1 22:40
哦，这样啊，那第一个怎么个情况，是不是答案有问题？作者: 韩啸0508 时间: 2012-4-1 23:22
那个，我表示也不太明白。。。刚才百度文库了一下，看到那个上面的答案应该是你选的B，因为没有时间教offspring，所以offspring的生存能力下降了，符合题目的作者: melody1101 时间: 2012-4-2 23:06
恩，知道啦，谢谢你了！作者: melody1101 时间: 2012-4-3 14:13 标题: 再问您几道题，嘻嘻，谢谢谢谢 1. Finland imposes a high tariff on the export of unprocessed hazel nuts in order to ensure that the nuts are sold to domestic processing plants. If the tariff were lifted and unprocessed hazel were sold at world market prices, more farmers could profit by growing hazels. Nevertheless, since all the processing plants are in urban areas, removing the tariff would seriously hamper the government's effort to reduce urban unemployment over the next ten years. 削弱 A. Some of the by-products of processing hazels are used for manufacturing plants and plastics. B. Other countries in which hazels are processed subsidize their processing plants. C. More people in Finland are engaged in farming hazels than in processing them. D. Buying unprocessed hazels at lower than would market prices enables hazel processors in Finland to sell processed nuts at competitive prices. E. A lack of profitable crops in driving an increasing number of small farmers in Finland off their land and into the cities. 答案是E.
2. The imposition of quotas limiting imported iron will not help the big Chinese ironmills. In fact, the quotas will help "mini-mills" flourish in the China. Those small domestic mills will take more business from the big Chinese ironmills than would have been taken by the foreign ironmills in the absense of quotas. 削弱最后一句话 A. Quality rather than price is a major factor in determining the type of iron to be used for a particular application. B. Foreign ironmills have long produced grades of steel comparable in quality to the iron produced by the big Chinese mills. C. Chinese quotas on imported goods have often induced other countries to impose similar quotas on Chinese goods. D. Domestic "mini-mills" consistently produce better grades of iron than do the big Chinese mills. E. Domestic "mini-mills" produce low-volume, specialized types of iron that are not produced by the big Chinese steel mills. 答案是E.
3. Editor: Articles in Gardening Magazine often encourage sales of the plants they describe, especially among people new to gardening. Therefore, we will not publish articles or accept advertisements praisng the beauty of rare wildflowers any more. Most such plants sold to gardeners have been difficult to propagate under cultivation; consequently, plant sellers often collect them in the wild. Our new policy is part of our efforts to cease this yearly plundering of our native plant populations.
削弱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 fall 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 law-cost techniques enabling rare wildflowers to be readily propagated in nurseries. 答案是E作者: 韩啸0508 时间: 2012-4-4 20:58
第一个题，题目说，芬兰要加关税来保护国产nuts的低价优势，这样，farmer就可以种hazel（榛子，nuts的一种）来增加收入，但是加工企业都在城市里，加税会阻碍降低失业率的目标。 题目有几点要注意，1， 几个元素之间的因果关系，加进口nuts的税》加工nuts的企业成本增加》企业在城里》阻碍城里失业率降低 2， farmer通过中nuts来profit 3， 结论是，加税阻碍失业率的降低 问削弱： E 是说 缺少有经济效益的农作物导致， 大量农民离开农村涌向城市 E其实说的是， 如果不加税，农民没利润，农民涌向城市也增加了失业人口作者: 韩啸0508 时间: 2012-4-4 21:06
第二个题目， 施行企业进口铁矿定额制不会有助于大型钢铁企业，事实上，有利于小企业，因为，小企业会抢走大企业的生意而不会被外企taken E， 小企业生产的是low volume铁， 和大企业生产的不一样 因为大小企业生产的产品不同，小企业不会抢大企业的生意（这里削弱的是抢大企业生意这部分）作者: xn8510 时间: 2012-4-4 21:17

第三题， article促进plant销售》我们不要听信这些关于这些珍稀花卉的宣传了》因为这些植物很难人工培植，花商们都是从野外采集来的》我们的新政策就是来制止这种破坏野生植物的 削弱 这个政策可以实现预期的效果（即，这个政策不会好使的） E 从卖野花中得来的税收是用来促进低成本培植技术的研究的 简而言之，题中本想通过不买花来保护花卉，可是卖花钱是来促进花卉培植的，达到削弱的目的作者: xn8510 时间: 2012-4-4 21:37
第三道题：
选项E：采花之后卖掉，所得收入可以用来支持使这种花在人工培育下能够繁殖的新技术的研究。因此，可以推断，如果公司继续刊登相关广告为这种花做宣传，那么，采花的人和卖花人会增多，卖花所得的收入增多，用于资助新技术研发的资金就增多。研发资金增多，有利于新技术的诞生，而新技术又会增加花的繁殖数量，长此以往，花的数量便会上升。由此可知，继续刊登广告的做法是明智的——对the wisdom of the policy 进行了削弱。。。作者: melody1101 时间: 2012-4-7 23:28

As a consequence, Autrnia oil exports dropped steadily as old fields became depleted. Autrnia's currently improving economic situation, together with less-restrictive regulations, will undoubtedly result in the rapid development of new fields. However, it can be concluded that the rapid development of new fields will result in higher oil exports, since........
答案是：the improvement in the economic situation in Autrniais expected to result in a dramatic increase in the proportion of Autrnians who want automobiles. 我选的是：many of the new oil fields in Autrnia are likely to be as productive as those that were developed during the period when Autrnia was a major oil exporter.
2、The growing popularity of television-based activities was widely predicted to result in a corresponding decline in newspaper reading. Recent studies have found that, in Britain, people who own televisions read, on average, significantly less newspaper than people who do not own televisions. But in itself this finding does very little to show that television use tends to reduce newpaper reading time, because..........
答案是： television owners in Britain predominantly belong to demographic group that have long been known to spend less time reading newspaper than the population as a whole does. 我选的是：many television owners in Britain have enough leisure time that spending significant amounts of time on the television still leaves ample time for reading newspaper作者: 韩啸0508 时间: 2012-4-14 18:46
第一题 A是一个石油出口商，由于政策限制新油田的开发，且旧的油田基本耗空，A出口量锐减。现在，开发政策松动了，新的油田会大量增加，但是，这并不能表明石油出口量会增加，------- 这道题 其实 是一道削弱题的变形。 削弱出口量会增加这个结论的。 答案 的意思是 因为国内经济快速发展，汽车拥有量增加（增加的车会消耗更多的石油》新开发的油田所产的油被增加的汽车消耗了），所以就不一定会有石油可供出口。 你选的那个 新油田和旧油田一样高产 其实是加强了 出口量会增加 这个结论的，作者: 韩啸0508 时间: 2012-4-14 18:56
第二题 看电视的人数增加会同比较少看报纸的人数。近来的研究发现，在英国，拥有电视机的人比没有电视机的人看报纸看得少。但是，这个结果并不能表明电视减少了报纸阅读时间，因为— 这个， 也是个削弱题的变形。 削弱电视减少看报时间。 答案 有电视的人本来就是那些不愿意看报纸的人（所以不看报纸不是因为有电视，而是本来就不喜欢看报纸） 你选的 有电视人很闲，既有充足的时间看电视又有时间看报纸 这是个无关选项。作者: melody1101 时间: 2012-4-19 22:03 标题: 一道归纳题，求助！ Transnational cooperation among companies is experiencing a modest recovery among United States firms, even though projects undertaken by one more companies under a collaborative agreement are less profitable than projects undertaken by a single company. The advantage of transnational cooperation is that such joint international projects may allow U.S. firms to win foreign contracts that they would not otherwise be able to win. 答案是：Transnational cooperation has in the past been both more common and less common than it is now among United States frims. 这个答案怎么想也不明白作者: bob9603 时间: 2012-4-20 09:28

你觉得这个解释会不会更好？作者: melody1101 时间: 2012-4-23 22:43 标题: 再问道假设题，嘿嘿，麻烦了 1. Bank depositors in the USA are all financially protected against bank failure since the government insures all individuals'bank deposits. An economist contends that this insurance is in part responsible for the high rate of bank failures, as it removes from depositors any financial incentive to find out whether the bank that holds their money is secure against failure. If depositors were more selective, then banks would have to be secure to compete for depositors' money.
The economist's argument makes which of the following assumptions?
答案是Potential depositors are able to determine which banks are secure against failure. 我选的是The difference in the interest rates paid to depositors by different banks is not a significant factor in bank failures.
2.Political advocacy groups have begun to use information services to disseminate information that is then accessed by the public via personal computer. Because many groups thus can bypass tradional news sources, whose reporting is selective and to present their political opinions directly to the public, information services present a more balanced depiction of the complexities of political issues than any tradional news source presents.
Which is an assumption on which the argument above depends？ 答案是：informatin on political issues desseminated through information services does not come almost entirely from advocacy groups that share a single bias. 我选的是：Traditional news sources seldom report the opinions of political advocacy groups accurately.
3. A great number of complex repair jobs carried out by Bec Repairs have to be rewarded under the company's warranty. The reworked jobs are invariably satisfactory. Thus when initial repairs are not adequate, it is not because the mechanics lack competence; rather, there is clearly a level of focused concentration that complex repairs require that is elicited more reliably by rework jobs than by first-time jobs.
假设是？ 答案是：There is no systematic difference in membership between the group of mechanics who do first-time jobs and the group of those who do rework jobs. 我选的是：Bec Repairs does not in any way penalize mechanics who have worked on complex repair jobs that later had to be rewarked.作者: 韩啸0508 时间: 2012-4-24 20:13
总的来说，关于assumption这种问题，一定要分清 无关 选项。 第一个 潜在顾客有能力辨别哪家银行是安全 ， 刚好填补了 If depositors were more selective, then banks would have to be secure to compete for depositors' money. 说明 顾客的more selective。 而你的答案 银行间利率的差别不会显著影响， 是个无关选项。 第二个， 结论的关键是 information service 对于 political更加balance。答案 说明 这些information service 提供的information不是来自于同一种政治观点 share a single bias. 你的那个 还是与结论无关。 第三个 文中说not because the mechanics lack competence，那就 mechanics的问题，答案补充说 两组工作人员体系上是没有差别的， 你的那个 无关
这里补充一下 关于 无关 即out of scope Out of Scope Answers. These answers simply miss the point of the argument and support issues that are either unrelated to the argument or tangential to the argument 再补充一下 strength和 assumption的区别 Strengthen questions ask you to support the argument in any way possible. This type of answer has great range, as the additional support provided by the answer choice could be relatively minor or major. Speaking in numerical terms, any answer choice that strengthens the argument, whether by 1% or by 100%, is correct. Assumption questions ask you to identify a statement that the argument assumes or supposes. An assumption is simply an unstated premise—what must be true in order for the argument to be true. An assumption can therefore be defined as what is necessary for the argument to be true. 这三段 都是从powerscore 的 LSAT 摘下来的 ，如果有空的话， 好好看看这本书，写的很好，作者编的很用心，条理很清楚，讲解很详细。CD 上有下载作者: melody1101 时间: 2012-4-24 22:40 标题: 太谢谢了，让我厚脸皮地再问一道评价题，(*^__^*) 嘻嘻…… The FMD, foot and mouth disease is caused by a virus transmitted to humans by deer ticks. Generally deer ticks pick up the virus while in the larval stage by feeding on infected black mice. However, certain other species on which the larvae feed do not harbor the virus. If the population of these other species were increased, more of the larvae would be feeding on uninfected hosts, so the number of ticks acquiring the virus would likely decline.
答案是：Whether the deer tick population's size is currently limited by the capability of animals for the tick's larval stage to feed on 我选的：Whether deer ticks that were not infected as larvae may become infected as adults by eating the deers on which infected deer ticks have fed.作者: 韩啸0508 时间: 2012-4-25 23:06
这个题 幼鹿吃了会感染，但是other species吃了不会感染，结论是如果other species 数量增加，更多的幼鹿就吃uninfected hosts（ black mice ），这样，感染的ticks（幼鹿） 就会减少。 这是一个 自带条件的结论， 评价的部分 感染幼鹿的数量受到 capability of animals for the tick's larval stage to feed on（幼鹿吃mice的能力）的限制 即说明当幼鹿吃的infected black mice减少时（或是more of the larvae would be feeding on uninfected hosts），the number of ticks acquiring the virus would likely decline 选项 刚好回答了 结论自带的条件 你的答案 幼鹿不感染但是成年后可能感染 是无关的作者: melody1101 时间: 2012-5-3 22:56 标题: 旧prep2里面的几道题，麻烦了！ On pacific islands, a newly arrived gecko species, the house gecko, is displacing the previously established mourning gecko in urban areas, but pupulations of the species are more stable in rural areas far from human settlement. The house gecko does not attack the nourning gecko, but in areas where insects congregate it prevents the mourning gecko from feeding on them.
Which of the following contributes most to an explanation of the difference between gecko populations in urban and rural areas? 答案是: In places where there are lighted buildings, insects tend to gather around the light. 我选的是: In urban areas, geckos are valued because they eat so many insects.
Some airlines allegedly reduce fares on certain routes to a level at which they lose money, in order to drive competitors off those routes. However, this method of eliminating competition cannot be profitable in the long run. Once an airline successfully implements this method, any attempt to recoup the earlier losses by charging high fares on that route for an extended period would only provide competitors with a better opportunity to undercut the airline's fares.
削弱 答案是: Airline executives generally believe that a company that once underpriced its fares to drive away competitors is very likely to do so again if new competitors emerge. 我选的是: When airlines dramatically reduce their fares on a particular route, the total number of air passengers in that route increases greatly.作者: 韩啸0508 时间: 2012-5-4 23:16
第一题，答案错了，你选的是对的，灯光影响壁虎吃虫。 第二题，压价竞争不会有利，因为一旦压价成功，任何补偿先前损失的加价行为都会给竞争对手一个低价出售的机会。 如果要削弱，就要说明，压价竞争是有用。 答案， 航空高管普遍认为一家公司如果曾经减过价，就极有可能在新的竞争对手出现的时候，再次减价（那么，一旦有竞争就减价，就不会再recoup的时候给对手机会了） 你的 当空航空公司急剧减价时，总的乘客人数会增加（这个是加强了，减价有利可图，人数增加，虽然价钱低了，总收入并不应定会减少）作者: melody1101 时间: 2012-5-5 15:51

However, many customers come to watch the celebrities who frequent the Hollywood, and they would prefer tall tables with stools because such seating would afford a better view of the celebrities. Moreover, diners seated on stools typically do not stay as long as diners seated at standard-height tables. Therefore, if the Hollywood repalced some of its seating with high tables and stools, its profits would decrease.
The argument is vulnerable to criticism on the grounds that it gives reason to believe that it is likely that 答案是：a customer of the Hollywood who would choose to sit at a tall table would be an exception to the generalization about lingering. 我选的是：a restaurant's customers who spend less time at their meals typically order less expensive meals than those who remain at their meals longer 这道题我觉得答案有问题，您觉得呢~
2.Traveler: Southern Airways has a far worse safety record than Air Dacentatia over the past few years, in terms of both the frequency of accidents and the severity of accidents. Therefore, although Air Dacentaria is slighty more expensive, I will choose it over Southern Airways for my flight from Pederton to Dacenta, since it is worth paying extra to have a safer flight. 削弱argument 答案是：Most Southern Airways flights, but not its flight from Pederton to Dacenta, use Sarmouth airport, which because of its mountainous location is one of the world's most dangerous. 我选的是：Although the frequency of accidents is greater on Southern Airways, on both airlines the proportion of flights that have accidents is very small.
3. When people evade income taxes by not declaring taxable income, a vicious cycle results. Tax evasion forces lawmakers to raise income tax rates, which causes the tax burden on nonevading taxpayers to become heavier. This, in ture, encourages even more taxpayers to evade income taxes by hiding taxable income.
The vicious cycle described above could not result unless which were true? 答案是：When lawmakes establish income tax rates in order to generate a certain level of revenue, they do not allow adequately for revenue that will be list through evasion. 我选的是：Taxpayers do not differ from each other with respect to the rate of taxation that will caouse them to evade taxes.
4.Because postage rates are rising, Home Decorator magazine plans to maximize its profits by reducing by one half the number of issues it published each year. The quality of articles, the number of articles published per year, and the subscription price will not change. Market research shows that neither subsribers nor advertisers will be lost if the magazine's plan is instituted.
Which provides the strongest evidence that the magezine's profits are likely to decline if the plan is instituted? 答案是：Many of the adverrisers that purchase advertsing space in the magazine will continue to spend the same amount on advertising per issue as they have in the past. 我选的是：With the new postage rates, a typical issue under the proposed plan would cost about one-third more to mail than a typical current issue would. 我觉得我选的是对的~作者: 韩啸0508 时间: 2012-5-5 22:12

第一个题，答案是对的。首先，要看明白，The argument is vulnerable to criticism on the grounds that it gives reason to believe that it is likely that这句话到底是问什么的， 他不是问以下哪项能削弱结论，而是问你结论本身在推导的过程中，犯了什么错误 他犯的错误是，认为选坐高椅子的人是少数（反过来说，如果大多数人都会倾向于选择高椅子，那么换成高椅子，就有可能有利可图，即结论忽视坐高椅子人多的这种可能） 你的，坐stools吃饭时间少的人，吃的也便宜（无关） 第二个，SA的安全记录不好，为了安全，即使AD贵，也要坐AD 答案，SA出事主要在Sarm，（这个人走PD线，不落在Sarm，安全的） 你的 ，两家航空出事的数量都挺小的（无关，SA还是不安全） 第三个，问出现这个怪圈的前提premise 答案，立法者没有充分考虑会出现漏税的情况（怎么较充分考虑？比如说，要收100的税，如果知道会被漏掉20块，那么就直接征收120块） 你的，纳税人对于交税观念上没差（无关） 第四个，这个OG原题啊 Evaluation of a Plan Situation In the face of rising postage costs, a magazine decides to cut in half the number of issues it publishes a year, though the quality and quantity of the articles as well as the subscription price will remain the same. Market research indicates that this plan will not cost the magazine any subscribers or advertisers. Reasoning How might the plan cause profits to decline? The magazine plans to maximize profits by reducing costs. What could lead to lower profits despite lower costs? Profits could decline if revenue is lost—and revenue will be lost if advertisers spend the same amount on advertising per issue when the number of issues is reduced by half. Therefore, the advertising revenues will be cut in half and a significant decline in profits is likely to result. A If the number of issues is cut in half and the postage rate per issue goes up by a third, then mailing costs still go down. This statement does not suggest that the plan will cause a decline in profits. B This statement is irrelevant to the magazine’s profitability given the stated point that the quantity and quality of articles will not change. C The passage says that the subscription price will not increase under the plan, so this statement provides no useful evidence. D Correct. This statement properly identifies evidence of a flaw in the plan. While market research shows that advertisers will not be lost, this statement shows that a significant amount of advertising will be lost. E Stable production costs would not lead to a decline in profits. 多一句嘴，OG是根本啊，不要盲目做题，要把题做透，总结和反思，SDCAR，要求大家，用英文思考，我知道这个难度有点高，题目都没看明白，怎么做题呢， 但是，用英文思考，可以帮你尽快的习惯英文的表达方式，是很有用的方法。总的来说，打好基础，反复思考，不要盲目贪求数量作者: melody1101 时间: 2012-5-5 23:11 标题: 嗯，您说的很有道理，我还有好多好多不足，望多多指教！ 1.The cotton farms of Country Q became so productive that the market could not absorb all that they produced. Cousequently, cotton prices fell. The government tried to boost cotton prices by offering farmers who took 25 percent of their cotton acreage out of production direct support payments up to a specified maximum per farm.
The govenment's program, if successful, will not be a net burden on the budget. Which is the best basis for an explanation of how this could be so? 答案是：Depressed cotton prices meant operationg losses for cotton farms, and the government lost revenue from taxes on farm profits. 我选的是：Farmers who wished to qualify for support payments could not use the cotton acreage that was withdrawn from producton to grow any other crop.
2. Bank depositors in the United States are all financially protected against bank failure because the government insures all individuals' bank deposits. An economist argues that this insurance is partly responsible for the high rate of bank failures, since it remoces from depositors any financial incentive to find out whether the bank that holds their money is secure against failure. If depositors were more selective, then banks would need to be secure in order to compete for depositors' money. 削弱 答案是：When the government did not insure deposits, frequent bank failures occurred as a result of depositors' fears of losing money in bank failures 我选的是: Before the government started to insure depositors against bank failure, there was a lower rate of bank failure than there is now.
3. Large natinonal budget deficits do not cause large trade deficits. If they did, countries with the largest budget dificits would also have the largest trade deficits. In fact, when deficit figures are adjusted so that different countries are reliably comparable to each other, there is no such correlation. 归纳 答案是：Reducing a country's national budget deficit will not necessarily result in a lowering of any trade deficit that country may have. 我选的是: Reliable comparisons of the deficit figures of one country with those of another are impossible.
4.Recently a court ruled that current law allows companies to reject a job applicant if working in the job would entail a 90 percent chance that the applicant would suffer a heart attack. The presiding judge justified the ruling, saying that it protected both employees and employers. The use of this court ruling as part of the law could not be effective in regulating employment practices if which of the following were true? 答案是：No legally accepted methods exist for calculaiting the risk of a job applicant's having a heare attack as a result of being employed in any particular occupation. 我选的是：The number of people applying for jobs at a company might decline if the company, by screening applicants for risk of heart attack, seemed to suggest that the job entailed high risk of heart attack.作者: 韩啸0508 时间: 2012-5-6 22:57
第一个，OG原题
Evaluation of a Plan Overproduction of cotton had led to falling prices. To boost prices, the government offered direct support payments to farmers who took 25 percent of their cotton acreage out of production. Surprisingly, this plan, if successful, will not be a net burden on the budget. What would explain why the plan will not a net burden ? It will not be a net burden only if as much or more will be added to the budget revenue as the amount paid out in support payments. What government revenues would account for such an increase in receipts? If, when cotton prices were falling, the cotton farmers had lower profits, they were paying lower taxes to the government. When cotton prices increase (because less cotton is offered in the market) and cotton farmers make greater profits, the government is able to tax those profits. In the program, the increased tax revenue compensates for the added expenditure. A Correct. This statement properly explains how no net budget loss would result from the plan. B The decline in cotton production in other countries does not explain why the program will not be a net burden on the budget. C The difference in cotton acreage does not explain how the government can recover the costs of the direct-payment plan. D This statement spells out an implication of the plan but does not help to explain how the plan would not be a net burden on the budget. The passage states that payments are made up to a specified maximum per farm, which suggests that large farms will get less per acre than smaller farms. 第二个 还是OG的
Argument Construction Situation An economist contends that the high rate of bank failures can partly be blamed on federal insurance of bank deposits. The insurance removes any financial incentive for depositors to seek those banks that are the most secure against failure. In the absence of more selective depositors, the banks need not be secure to compete for deposits. Reasoning What assumption underlies the economist’s argument? The economist argues that banks would have to be more secure in a competitive environment with more discriminating depositors. The economist encourages potential depositors to be more selective in choosing a bank and therefore must believe that many depositors have sufficiently sound ideas about what makes a bank secure against failure and can often apply those ideas in determining which banks are secure. A Although this statement explains how a bank failure may occur, it is not a necessary assumption for the economist’s argument about how depositors choose a bank. B The argument never discusses multiple accounts, so this statement cannot be assumed. C The economist argues that depositors are not careful in selecting banks; this statement contradicts that position, at least for some depositors, so it cannot be assumed. D In arguing about choosing banks, the economist mentions nothing about the relation of interest rates to bank failures, so this statement is not assumed. E Correct. This statement properly identifies the economist’s underlying assumption that potential depositors are able to determine which banks are more secure. 第三题，财政赤字不一定会导致贸易赤字》减少财政赤字不一定会减少贸易赤字 第四题，90%患心脏病概率，公司就可以拒绝申请者， 削弱， 没有一个正规的方法来计算患心脏病的概率（90%没法确定算出来啊）
