10.7某NN:

有一种迁徙的鸟吃海龟蛋。最近海龟蛋数量下降。但是argue鸟不会受影响，因为只要鸟儿呆的时间长，就可以迟到足够的蛋。问题是：怎么削弱这种说法。

我选的是：鸟早吃完早迁徙，晚吃完就不会再繁殖了。

找了找：极类似

不好意思贴错了。。这几天看得我头都晕了。。是这题~

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?

 

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

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

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

D.      The crabs do not conceal their eggs.

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

楼主贴出来的题选什么啊？为什么？

谢谢

不好意思刚看到

这题选E

削弱题注意看结论，本题为poses no serious threat to the migrating shorebird populations

要削弱就找可以说明确实对population有影响的选项
