大全-II-2 未讨论过的题.
. The increased concentration of salt in the bay, which is the result of recent drought and high temperatures, will cause many fish to die. Shrimp, however, can tolerate high salt levels; the shrimp industry will not, therefore, be hurt by the increased concentration of salt.
Which of the following statements, if true, would weaken the argument above?
(A) Some fish will migrate to areas that have lower concentrations of salt.
(B) Lack of rainfall for extended periods of time lowers the water level of bays.
(C) The organisms on which young shrimp feed cannot survive in such salty waters.
(D) Increased water temperature often causes shrimp to multiply more quickly.
(E) Shrimp are more abundant in areas of the bay that are sparsely populated by fish.
E为什么不对？答案选C，为什么这道题很多人问没有人回答。

有哪个人好心就帮忙看看吧，让我死的明白点。

(E) Shrimp are more abundant in areas of the bay that are sparsely populated by fish. 貌似这是支持原结论吧

再问一下 industry 到底是受到威胁呢？还是没有？我感觉题目是要削弱industry受到威胁的推断。
DE都表示虾变多了额，所以industry不会受到威胁，只不过D中说温度，E说鱼少了虾多。

weaken the argument，就是说虾的数量会受到影响（会减少），你弄反啦

Shrimp are more abundant in areas of the bay that are sparsely populated by fish.
译文：虾在鱼量稀少的海岸更丰富。对不对？
salt使得鱼少了，虾多了

对的，但这句话是支持原结论的

(C) The organisms on which young shrimp feed cannot survive in such salty waters.
C很明显是对的，作为虾的食物的那些生物无法在咸水生存，提供了一个the shrimp industry will , therefore, be hurt by the increased concentration of salt.
因为虽然虾能在咸水生存，但却因没食物而减产，weaken the argument

E) Shrimp are more abundant in areas of the bay that are sparsely populated by fish.
简单的说，鱼少的海湾虾就多，既然虾多那捕虾的产量也就增加了，支持了argument...
削弱要抓住虾变少的那个选项
