GWD17-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.
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.
The decline in the number of crabs on Delaware’s beaches is due to the harvesting of crabs by humans.
There are more crabs on Delaware’s beaches than in any other area that the migrating birds pass through.
The crabs do not conceal their eggs.
The earlier in the season the shorebirds complete their migration, the more likely they are to breed successfully.
E
我认为E和题目没有关系，人家的argument说的是poses no serious threat to the migrating shorebird populations，又没说the success of the shorebird's breeding. 我选D。因为我作者说只要这些birds留得时间久，他们就可以找到足够的eggs吃。但是如果crabs没藏eggs，就是说所有的eggs能找到的都找到了，那么留得时间再长也不可能再“无中生有”出一些eggs给他们吃。所以weaken了argument。
10. GWD17-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.
Which of the following is an assumption on which the press secretary’s argument depends?
Canceling highway projects was not the only way for the President to punish legislative districts controlled by opposition parties.
The scheduled highway projects identified as wasteful in the report were not mostly projects in districts controlled by the President’s party.
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.
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.
Reports by nonpartisan auditors are not generally regarded by the opposition parties as a source of objective assessments of government projects.
Answer: B 人家题目中已经说了They offer as evidence the fact that 90 percent of the projects canceled were in such districts，而且all of the canceled projects had been identified as wasteful in a report written by respected nonpartisan auditors。B只是换了个说法把facts又说了一遍，我认为不构成assumption。我选了D。用denial test，如果president的那些projects更贵的话，就说明president的projects也可能是wasteful的，但他cancel的又大部分不是他自己的project，所以构成偏袒嫌疑。
请大家指教~~

E The earlier in the season the shorebirds complete their migration, the more likely they are to breed successfully.
If these birds have to stay in Delaware's beaches longer to get enough crab eggs, they will arrive at their destination later. That means these birds will complete their migration later, therefore, their success rate of breeding will be lower. This will lead to less population of the bird, hence, poses threat to the bird populations.
B. The scheduled highway projects identified as wasteful in the report were not mostly projects in districts controlled by the President’s party.
Here, the scheduled projects are those which are not cancelled.
If most of the scheduled projects - i.e. not cancelled projects - which are identified as wasteful were in the districts controlled by the President's party while most cancelled projects are from the districts controlled by opposition partyes, it implies that these projects are handled to benefit to the districts controlled by President's party. It will contradict to what the secretary said - "So the President’s choice was clearly motivated by sound budgetary policy, not partisan politics."
So the secretary has to make this assumption in order to make her conclusion true.
B implies that the President didn't do anything to benefit the districts of his party, so B does support the secretary's conclusion, therefore, it is one of the assumption of THE SECRETARY's conclusion.
If B is not true, that is, most uncancelled projects which are actually wasteful are in the districts controlled by the president, it means the presidents make the unfaire decision to protect his party.
LS 的MM，题干说的是 那些鸟迁徙去繁殖地路过的时候要吃蟹蛋，现在蛋少了，鸟可以留久一点来吃，所以不影响鸟的繁殖。
E，断桥。留得久反而会降低鸟的繁殖率。所以是 weaken

Q9 我是这么想的 不知道对不对 如果那些projects都是在总统党所控制的区域，那么即使被取消了 也不会有关于报复的讨论。只有在这些projects都不是在总统党所控制的区域这个前提下，才会有人出来怀疑总统是否在报复他的敌对党派。作者: Polka 时间: 2010-7-27 10:27
啊，貌似没有人纠结于B啊 B. The decline in the number of crabs on Delaware’s beaches is due to the harvesting of crabs by humans. 为毛大家都说无关呢？ 我当时徘徊在BE之间，最后觉得E无关，选了B。
题目结论是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.
那我们应该削弱的不是 by remaining longer in Delaware, the birds will be able to eat enough crab eggs to allow them to complete their migration. 这个原因吗？跟它迁徙后的繁殖没什么关系。
相反，看B项，蛋的减少是due to the harvesting of crabs by humans.这么说，即使鸟在那里待得再久也没用了，因为蛋都被人收走了。
我也刚做到这个题，不是高手说下想法，我们要weaken的结论是蛋的减少不会威胁到迁徙鸟的数量。 如果选B的话，只能说明蛋被人收走了是引起蛋减少的原因，文章还是可以继续讨论蛋的减少不会威胁到迁徙鸟的数量，实际上我们开始推理的起点就是蛋减少了。所以无关 答案E，逻辑链就是前提是蛋减少了（我们管他是什么原因减少的），鸟可以在D停留的久点吃足够的eggs去完成迁徙，但是越早的完成迁徙繁殖就越成功，停留过久会使繁殖率下降也就导致鸟数量的下降，weaken了结论作者: morningzc 时间: 2010-8-20 11:00

The conclusion is the decline of crab eggs poses no serious threat to the migrating shorebird populations.
If E is true, the shrinking egg numbers would cause the birds stay longer at the beach, delay their migration, and reduce the chances of their reproduction success. Thus, E weakens the conclusion.作者: yangmars 时间: 2011-5-9 14:49
可是 使繁殖率下降，跟鸟迁徙的数量有毛关系呢？鸟迁徙到了这里，然后蛋少了，他们停留的久了，吃完之后再继续迁徙，迁徙完了，繁殖率下降了，那么鸟的数量减少了，但那也是迁徙之后的事了啊，跟本次的迁徙的鸟的数量有什么关系呢？难不成文中的问题说不会减少迁徙的数量的是还包括了下次迁徙的鸟的数量也不会受影响的意思吗？如果是这样，那下次迁徙的鸟肯定会少，但是这样子不就是从答案去对文章了么，文章里并没有给出说是下次迁徙的鸟的数量减少的意思啊?晕，作者: 若雪 时间: 2011-8-5 11:00
UP~~同意LS观点。。。breeding之后的数量和migrating population说的东西不一样吧。。。作者: sdcar2010 时间: 2011-8-5 12:22

E 其实就是在说,birds越早动身迁徙,越有可能吃到足够的eggs,从而成功完成迁徙. the eariler, the more likely. 就是说越晚走,越没吃的, 越不可能成功完成迁徙. 还是在说egg数两不足. 削弱题干作者: sdcar2010 时间: 2011-8-6 11:29
One-child policy poses no threat to the growing Chinese population because it only affect the size of the next generation for years to come.
Is this above statement valid? Is the word population llimited to the current head count ONLY?

migrating shorebird populations, this is not THIS year's population. This the population of this species!
我默默的。。来回答了。。不valid. 我理解是因为growing是逐渐增长的。。没有尽头的那种。。所以包括未来的next generation. 我觉得题目中migrating作为定语修饰bird population，应该不会他们一直迁移到永远没有结束吧。。所以才觉得特指他们这次迁移的鸟..... 好像脑子就是转不过来。。。咳咳。。。。不好意思吖。。又要麻烦sdcar了。。。>_<!作者: sdcar2010 时间: 2011-8-7 03:45

这个解释非常好
But all of the canceled projects had been identified as wasteful in a report written by respected nonpartisan auditors
这个报告如果没有调查反对党控制的选区是否有浪费的话，比方说，这个报告的对象如果全部是总统控制的选区的话，报告的结论-全部是浪费-是无法支持发言人的。

我想问scheduled等于not cancelled，那么这些scheduled projects 已经列入计划之中，最终还是会被cancelled，所以我认为在cancelled projects大部分是是反对党派控制的，说明总统是偏袒的。B：scheduled projects中大部分浪费的计划也都是反对派控制的，仍然说总统是偏袒的。求解答！作者: sylviama 时间: 2013-9-19 20:42

"They offer as evidence the fact that 90 percent of the projects canceled were in such districts."
这句话已经指出了president在偏袒了吧，为什么还需要B来给出president在偏袒的前提？作者: dongjiaozhi 时间: 2014-4-3 11:11
只能是B
试想如果有200个项目是wasteful的, 各有100个在总统选区和反对党选区,总共取消了100个,而90%的被取消的项目在反对党区域,即反对党被取消了90个,而总统选区只取消10个,结果就是极大的不公平.
而B说大多数wasteful的项目不再总统选区, 可以假设反对党180个wasteful的项目取消90个,留90个,总统20个wasteful取消10个留10,这样大家被取消的wasteful都是一半,公平.作者: Rose_1314 时间: 2014-4-17 15:35
