34. GWD17-Q34:
DuringthemonthofMay, crabs arrive on Delaware's beaches to lay eggs.Certain shorebirds depend on these eggs for food duringtheir 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 ofthe 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.
虽然这道题目能有排除法选出E
就是感觉E 说的是鸟越早到,吃到的机会越大,这个和题目中说的最后一句话:by remaining longer in DElaware,the birds will be able to eat enough crab eggs to allow them to complete their migration.  真好吻合,怎么有削弱的效果呢

可是conclusion说的是threaten the number of the migrating birds啊,和生下来的新bird宝宝有什么关系呢 ...

第一年不影响,第二年开始就影响了呀。

注意原文中的by remaining longer, 我之前错选就是因为忽略了这句。。

所以说weaken了原文这句话:by remaining longer in Delaware。

既然越早完成迁徙越好,那鸟当然不应该在D这个地方呆更长的时间。然后就顺着weaken了结论了呗

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.

The beach is only one intermediate stop on the migration route, not the end thereof.
