【正文】 GWD13Q22: 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. 注射鎮(zhèn)靜劑后才能把雷達全重新套上 Female rhinoceroses that have been frequently recollared have significantly lower fertility rates than uncollared females. Probably, therefore, some substance in the tranquilizer inhibits fertility. 結(jié)論：鎮(zhèn)靜劑導致低懷孕率 Which of the following is an assumption on which the argument depends? 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. The fertility rate of uncollared female rhinoceroses in the park has been increasing in the past few decades. Any stress that female rhinoceroses may suffer as a result of being immobilized and handled has little or no negative effect on their fertility. 排出他因 The male rhinoceroses in the wildlife park do lose their collars as often as the park?s female rhinoceroses do. The tranquilizer used in immobilizing rhinoceroses is the same as the tranquilizer used in working with other large mammals. GWD13Q38: Frobisher, a sixteenthcentury English explorer, had soil samples from Canada?s Kodlunarn Island examined for gold content. Because high gold content was reported, Elizabeth I funded two mining expedit。因為不在計算范圍內(nèi)。這樣反而支持結(jié)論，所以不是假設(shè)。有些鹽被消耗掉。故為答案 E。將 A取非 ，則過去一百年的鹽度增加量作為速率是高估了，則算出年齡比實際小。 結(jié)論。 算法為：目前鹽度 /過去 100年的鹽度增加量 =多少個世紀從零鹽度到目前鹽度。 SORRY。所以原文的 resulting increase 是指過去一百年的鹽分增加量，而不是簡單的過去某個時間段的鹽度增加量。如果是過去幾百年，應該為 over the past hundreds of years。 后來他意識到 E錯誤，應該選 A： 答案應該是 A。所以它不能使結(jié)論不能成立，只能使結(jié)論可能不成立。 A 選項攻擊的是速率，但是，它只能可能性的攻擊它，就是說，如果用的 數(shù)據(jù)恰好是不正常的數(shù)據(jù)，則能影響它，但也有可能取的數(shù)據(jù)正好。如果如 E 取非所說，即有些河流流入的鹽沒了，則目前的 salt levels 低估了，算出的年度偏小，結(jié)論不能成立。因為起點是 saltfree state，即零。 2。反正這是個最難攻擊的詞。這個速率的最大特點是原文沒告訴怎末計算出來，任何關(guān)于他如何計算出來的說法都是典型的加入自己的想象，這個最大特點是我們很難攻擊它，因為不知如何算出速率，不知用那一年的數(shù)據(jù)，不知如何加權(quán)以消除偏差。 resulting increase 。 1。即 B取非不一定使結(jié)論不成立。 Which of the following is an assumption on which the argument depends? A. Repairing typical collision damage does not cost more in Greatport than in Fairmont. B. There are no more motorists in Greatport than in Fairmont. C. Greatport residents who have been in a collision are more likely to report it to their insurance pany than Fairmont residents 。 GWD8Q22*: When storing Renaissance oil paintings, museums conform to standards that call for careful control of the surrounding temperature and humidity, with variations confined within narrow margins. Maintaining this environment is very costly, and recent research shows that even old oil paint is unaffected by wide fluctuations in temperature and humidity. Therefore, museums could relax their standards and save money without endangering their Renaissance oil paintings. Old oil paint 在適度溫度變化很大的情況向不受影響 無需控制適度溫度來保存 oil paintings Oil paint 只是 oil painting 的一部分。對于 A所說的 new panies 產(chǎn)生的新工作比 previously established panies 產(chǎn)生的新工作多和原文的結(jié)論沒關(guān)系。新工作分兩部分 previously established panies 產(chǎn)生的新工作和 new panies 產(chǎn)生的新工作。 D錯： 文章的結(jié)論排除了工人是導致滿意度差別的原因 ,而是 BALABALA的原因 (那個句子太長了 ),對 D 取非 ,即公司有懲罰工人的措施 ,這個與結(jié)論是否由工人導 致兩次修理的滿意度差別無關(guān) . 文中排除了一種原因，削弱可以說這種原因正是導致了結(jié)論。 A 答案的核心 在 no systematic difference XXX between 1 and 2. 所以 difference 后面的東東盡可以隨便變。首次修理不太充分，不是修理人員沒水平，而是要求的側(cè)重點不同，二修要求高點。 There is no category of repair jobs in which Ace Repairs invariably carries out firsttime jobs satisfactorily. 反前提 If say, members of group A who do the firsttime repair are mostly newbies, and members of group B who do the rework are more experienced, then the author39。他因就是除了文中劃線部分以外能導致滿意度改變的。GAP Which of the following is an assumption on which the argument depends? i The number of school nurses employed by Renston?s elementary schools has not decreased over the past ten years. Children who are allergic to the chemicals are no more likely than other children to have allergies to other substances. Children who have allergic reactions to the chemicals are not more likely to be sent to a school nurse now than they were ten years ago. NOT+他因 削弱 The chemicals are not monly used as cleaners or pesticides in houses and apartment buildings in Renston. Children attending elementary school do not make up a larger proportion of Renston?s population now than they did ten years ago. GWD7Q27: A significant number of plex repair jobs carried out by Ace Repairs have to be reworked under the pany?s warranty. The reworked jobs are invariably satisfactory. When initial repairs are inadequate, therefore, it is not because the mechanics lack petence。 Industry lobbyists will be unable to dissuade the government from regulating the industry. Assembly of the product produced according to government manufacturing specifications would be more plex than current assembly procedures. None of the seven small panies currently manufactures the product to a set of specifications that would match those the government would institute if the industry were to be regulated. 如果一開始就有小公司已經(jīng)符合新規(guī)定，那么它沒有必要 Convert也就不存在能否 Afford的問題了。（ average*數(shù)量 =總量） 人口增加 必須進口大米。t drop. GWD5Q21: In Teruvia, the quantity of rice produced per year is currently just large enough to satisfy domestic demand. Teruvia?s total rice acreage will not be expanded in the foreseeable future, nor will rice yields per acre increase appreciably. Teruvia?s population, however, will be increasing significantly for years to e. Clearly, therefore, Teruvia will soon have to begin importing rice. T 的大米生產(chǎn)正好自給自足。 Televisions assembled in Vernland have features that televisions assembled in Borodia do not have.
