GWD-17
Q9:
Press Secretary: Our critics claim that the President’s recent highway project cancellations demonstrate a vindictive desire to punish legislative districts controlled by opposition parties. They offer as evidence the fact that 90 percent of the projects canceled were in such districts. But all of the canceled projects had been identified as wasteful in a report written by respected nonpartisan auditors. So the President’s choice was clearly motivated by sound budgetary policy, not partisan politics.
发言人：有评批说总统最近取消了一些修建高速公路的计划是出于对反对党的报复，其证据是这些被取消的高速公路计划90%都是在反对党控制的地区。事实上，这些取消的计划 是基于审计报告，这些报告显示这些计划是浪费的，而这些报告的制作者是一些受到尊敬的无党派审计员。所以总统的这个决定非常清楚的是基于预算政策而非缘党派之争的举措。
(其逻辑关系是：反对党说总统说不修一些公路是出于报复，发言人说不是出于报复，而发言人的理由是，无党派的审计人员说了这些修这些公路是浪费钱。)
Which of the following is an assumption on which the press secretary’s argument depends? (找一个理由来支持发言人)
Canceling highway projects was not the only way for the President to punish legislative districts controlled by opposition parties.也可能不是唯一的，但也可能是其中之一。需要的答案是说这不是报复措施，此选项没起来这个作用。
The scheduled highway projects identified as wasteful in the report were not mostly projects in districts controlled by the President’s party. 被认为是浪费而没有被取消的高速公路项目大多都不在执政党控制的地区。如果说因为被取消的项目可以作为执政党在报复反对党的话，那同样的应该取消而没有被取消的项目不在执政党地区就可以反证执政党没有报复反对党。(对不起，这个好象很绕)
The number of projects canceled was a significant proportion of all the highway projects that were to be undertaken by the government in the near future. 没有起到证明不是报复的目的，所以不是正确答案。
The highway projects canceled in districts controlled by the President’s party were not generally more expensive than the projects canceled in districts controlled by opposition parties如果取消的经审计是浪费的，那么没取消的只要不是比取消的便宜，就不能证明也不是浪费的。
Reports by nonpartisan auditors are not generally regarded by the opposition parties as a source of objective assessments of government projects.就是说反对党不相信无党派审计人员所做的报告是中立(客观)的。相当于说发言人拿出的证据其他人不认可，明显是个削弱选项，而非加强。
Q11:
Some species of Arctic birds are threatened by recent sharp increases in the population of snow geese, which breed in the Arctic and are displacing birds of less vigorous species. Although snow geese are a popular quarry for hunters in the southern regions where they winter, the hunting season ends if and when hunting has reduced the population by five percent, according to official estimates. Clearly, dropping this restriction would allow the other species to recover.
一些北极的鸟受到近来数量急速增长的雪鹅的威胁，这种生长在北极的雪鹅会把其它没那么有活力的(闪的快的)鸟赶走。尽管雪鹅在冬天会在南方过冬，同时雪鹅是猎人通常的猎获物，但是有规定，只要当管理部门认为捕猎而让捕猎物的数量减少了百分之五的话，整个捕猎季节就结束了。显然，如果把这个规定放宽的话，那么其它品种的鸟就可以recover。
Which of the following, if true, most seriously undermines the argument?
Hunting limits for snow geese were imposed many years ago in response to a sharp decline in the population of snow geese. 以前是为了让雪鹅的数量增多因为确定了只能打5%，，而现在想让雪鹅的数量减少，不是就应该打得比5%更多吗?与要的答案相反。
It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date. 因为管理部分估计的是整个猎物的数量，也就是说是包括除雪鹅以外的鸟类。所以这样的决定有可能是让更多的其它没有雪鹅跑的快鸟(也就是想要保护的鸟)被猎人打的更多。正确。
The number of snow geese taken by hunters each year has grown every year for several years.被打的多了还是让雪鹅的数量猛增，那不是说就应该被打得更多吗?错误
As their population has increased, snow geese have recolonized wintering grounds that they had not used for several seasons. 没有信息说雪鹅可以去的地方猎人不能去，既然猎人可以去就涉及到可以打多少的问题，以及打了后有什么结果。明显这个选项没有回答这个关键问题，无关。
In the snow goose’s winter habitats, the goose faces no significant natural predation.可以推出来的信息是如果猎人不收拾它，就没有什么可以收拾它了。于是又回到老问题，如果让5%这个限制往上升是不是就可以达到保护其它鸟的目的?无关
Q23:
Because visual inspection cannot reliably distinguish certain skin discolorations from skin cancers, dermatologists at clinics have needed to perform tests of skin tissue taken from patients. At Westville Hospital, dermatological diagnostic costs were reduced by the purchase of a new imaging machine that diagnoses skin cancer in such cases as reliably as the tissue tests do. Consequently, even though the machine is expensive, a dermatological clinic in Westville is considering buying one to reduce diagnostic costs.
因为从外观上(目测)不能准确地分辨皮肤变色和皮肤癌变，临床皮肤科医生需要用病人身上的组织作实验才能确诊。W医院买了一种新的图象设备，用这种设备来检查皮肤癌的可靠性是和用组织检查一样的，同时可以减少检查的费用。结果，即使这个设备很贵，一个W地的皮肤诊所也在考虑买这个设备以降低诊断费用。
Which of the following would it be most useful for the clinic to establish in order to make its decision?
Whether the visits of patients who require diagnosis of skin discolorations tend to be shorter in duration at the clinic than at the hospital 呆在医院和诊所的时间长短区别和病人用不用这个设备没有必然联系。无关。
Whether the principles on which the machine operates have been known to science for a long time 这个设备的工作原理和有没有病人用也没有必然联系。
Whether the machine at the clinic would get significantly less heavy use than the machine at the hospital does 如果诊所比医院用的机会少得多就说明病人少得多，正确。
Whether in certain cases of skin discoloration, visual inspection is sufficient to make a diagnosis of skin cancer 题干已经将这个问题回答并作为前提，无关。
Whether hospitals in other parts of the country have purchased such imaging machines 其它地方的医院买没买和W地的诊所买不买没有关系，只和W地的病人用不用有关系。
Q30:
In a study conducted in Pennsylvania, servers in various restaurants wrote “Thank you” on randomly selected bills before presenting the bills to their customers. Tips on these bills were an average of three percentage points higher than tips on bills without the message. Therefore, if servers in Pennsylvania regularly wrote “Thank you” on restaurant bills, their average income from tips would be significantly higher than it otherwise would have been.
在P地进行的实验：在数个餐厅里随机的抽出一些帐单，然后让侍者在这些帐单上写上“谢谢你”。拿到这些帐单的顾客比其他的顾客平均多付了百分之三的小费。因此，如果P地的侍者经常在帐单上写上“谢谢你”，他们的平均小费收入就会比不写这句话高很多。
Which of the following is an assumption on which the argument relies?
The “Thank you” messages would have the same impact on regular patrons of a restaurant as they would on occasional patrons of the same restaurant. 题干并没有说试验对象是或者不是常客，所以其结论也不是建立在这上面。无关
Regularly seeing “Thank you” written on their bills would not lead restaurant patrons to revert to their earlier tipping habits.以下情况不会发生：每次都看到这句话就相当于没看到这句话了。打个比方，平时去的小饭馆，一个小姐平时都很严肃，偶尔会对我微笑一下，我会觉得得到她的微笑服务是特殊的。而如果另一个小姐每次对每个人都微笑，我就不会觉得她的微笑是特殊的了。因为感觉特殊所以会多给小费，这个选项告诉我们：即使每次去看到同样的“谢谢你”也同样会觉得特殊。正确。
The written “Thank you” reminds restaurant patrons that tips constitute a significant part of the income of many food servers. 没有信息让我们知道顾客给小费的多少定是考虑到这个小费对侍者有多重要。无关。
The rate at which people tip food servers in Pennsylvania does not vary with how expensive a restaurant is. 题干告诉我们小费平均增加了百分之三，同时并没有说试验的餐厅的价位差异，而只是说了“不同的餐厅”，所以无法推出给小费的多少是和餐费的多少有关系。无关。
Virtually all patrons of the Pennsylvania restaurants in the study who were given a bill with “Thank you” written on it left a larger tip than they otherwise would have. 这个很大部分人不等于所有人，而且基本上这个选项是重复题干的内容，也就是仍在描述试验中的情况，而我们需要的答案是把题干中的依据和事实之前搭一个桥。具体来说就是试验中在帐单上写谢谢，顾客就给了比较多的小费。结论是如果坚持同样的做法，侍者就会稳定的得到更多的小费收入。其中的gap就是试验中给一部分帐单上写谢谢和以后经常性的给帐单上写谢谢是一样的效果。此项没有搭上这样的桥，所以无关。
Q34:
During the month of May, crabs arrive on Delaware’s beaches to lay eggs. Certain shorebirds depend on these eggs for food during their annual spring migration to their northern breeding grounds. Delaware’s crab population has declined recently. This decline, however, poses no serious threat to the migrating shorebird populations: by remaining longer in Delaware, the birds will be able to eat enough crab eggs to allow them to complete their migration.
三月，螃蟹到D海岸来下蛋。 一种海岸鸟在春季向北方它们的繁殖地迁徙时以食螃蟹蛋为生。D地的螃蟹数量最近有所下降。但是下降的程度还没有威胁到这种迁徙鸟的数量，只要在D地呆长一点的时间，这种鸟就可以吃到足够多的螃蟹蛋以支持它们完成成移栖。
Which of the following, if true, most seriously weakens the argument?
No other food available to the birds on Delaware’s beaches is as nutritious and accessible as are crab eggs.这是有可能的，但是题干已经说了只要呆的时间差长一点，他们就可以吃到足够多的螃蟹蛋。
The decline in the number of crabs on Delaware’s beaches is due to the harvesting of crabs by humans. 是什么造成螃蟹数量下降的不在读者讨论范围，需要削弱的是鸟不可能吃到足够的螃蟹蛋，或者吃到了也会影响鸟的数量。
There are more crabs on Delaware’s beaches than in any other area that the migrating birds pass through. 这是在加强，可以用来支持结论，但是我们需要的是削弱。
The crabs do not conceal their eggs.螃蟹不藏蛋，只能说明有可能下一个就被鸟吃一个，但是蛋的总的数量是否满足鸟的需要并没有说明。这样就有两个可能。既然有两个可能就只能当无关选项处理。
The earlier in the season the shorebirds complete their migration, the more likely they are to breed successfully. 就是说因为要吃足够的蛋，所以要在D地呆久一点------蛋吃够了，但是到达北方的时间也晚了，这样鸟下的就少了-----鸟的数量就会受影响。
