标题: gwd17-34急求问

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.

    • 我是在DE徘徊，答案是E，我觉得D是不是也有些道理。


    Crab没有把Egg藏起来，该吃的已经吃完了，Shorebird再等下去也不会有什么作用，所以weaken.

    楼主还没有习惯gmat的思维方式，不可加进任何自己的推论。答案是E

    Which of the following, if true, most seriously weakens the argument?




    1. No other food available to the birds on Delaware’s beaches is as nutritious and accessible as are crab eggs. 无关， 即使没有， 不能削弱靠延长时间来得到足够鸟蛋的可能性

    2. The decline in the number of crabs on Delaware’s beaches is due to the harvesting of crabs by humans. 无关

    3. There are more crabs on Delaware’s beaches than in any other area that the migrating birds pass through. 增强

    4. The crabs do not conceal their eggs. 无关

    5. The earlier in the season the shorebirds complete their migration, the more likely they are to breed successfully.

    题干的推导关系为：蟹蛋量下降，但没有影响靠蛋哺育的鸟的数量，原因是鸟可以通过延长找蛋的时间来吃到足够多的蛋。E说越早来，哺育越成功。即晚来的可能失败，削弱题干推导关系。 削弱原推导所赖的依据

    我的理解如下：

    the birds will be able to eat enough crab eggs to allow them to complete their migration.

    这是文章的结论，结论只提到了migration是否成功，根本没有提到breed是否成功．

    因此我认为只要migration是否成功就可以了，而breed是否成功就变成了无关．所以我坚决的把Ｅ排除了．

    agree, unless the "migration" is defined to include the breed part.

    thanks

    I vote for E

    作者: xinyp    时间: 2008-7-1 19:18

    那么B为什么错呢？B说crab都被抓走了，鸟再等也不会有更多的蛋可吃了，不是削弱吗？

    作者: xinyp    时间: 2008-7-1 19:25
    额，想错了，crab只是下降了，但不是绝迹了。剩下的crab可以慢慢下蛋。这个选项是在解释crab为什么数量下降，属于无关项。

    我也来尝试解释.请指教.

    My opinion: 结论是，只要remaining longer in Delaware就会no serious threat to the migrating shorebird populations。结论：不会影响它们的数量。理由，能够吃到足够的蛋。E 答案对于结论的削弱，在于提出他因影响数量。

    不同意GawainERIC的观点,原题说的是不会对迁徙中（migrating）的shorebird的population带来影响，而不是会对其迁徙活动带来影响！！Ｅ选项中谈到ｂｒｅｅｄｉｎｇ，自然是影响其ｐｏｐｕｌａｔｉｏｎ的因素了。

    作者: vivien_hu    时间: 2009-4-1 22:07

    我想题目给出的逻辑关系是：在D待得越久——吃到足够蛋——可以完成迁徙——不会影响S数量

    E选项：是越早完成迁徙——S成功生育

    成功生育=不会影响S数量

    果一致，但是因是相反的。。。所以削弱

    欢迎指正

    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.

    原文结论是：通过remain LONGER, 鸟就能吃够eggs 来完成他们的migration.

    Which of the following, if true, most seriously weakens the argument?

    1. No other food available to the birds on Delaware’s beaches is as nutritious and accessible as are crab eggs.
                      

    2. The decline in the number of crabs on Delaware’s beaches is due to the harvesting of crabs by humans.
    3. There are more crabs on Delaware’s beaches than in any other area that the migrating birds pass through. 
              
    4. The crabs do not conceal their eggs.
    5. The earlier in the season the shorebirds complete their migration, the more likely they are to breed successfully.

     只有e选项说的内容与时间有关啊 而且还是用比较的形式写出来的 多好的选项啊
