GWD4 q27

Q27:

In parts of the Caribbean, the manatee, an endangered marine mammal, has long been hunted for its meat.  Having noted the manatee hunters’ expert knowledge of manatees’ habits, local conservationists are encouraging the hunters to stop hunting and instead to take tourists on boat rides to see manatees.  Tourist interest is high, so the plan has promise of achieving the twin goals of giving the former hunters a good income and helping ensure the manatees’ survival.



Which of the following, if true, raises the most serious doubt about the plan’s chance of success?

1. Many tourists who visit these parts of the Caribbean are uninterested in manatees and would not be willing to pay what the former manatee hunters would have to charge for boat rides to see manatees.
   
2. Recovery of the species would enable some hunting to continue without putting the manatees’ survival in jeopardy again.
   
3. In areas where manatees have traditionally been hunted for food, local people could easily replace the manatee meat in their diets with other foods obtained from the sea.
   
4. There would not be enough former manatee hunters to act as guides for all the tourists who want to see manatees.
   
5. To maintain their current income, manatee hunters who switched to guiding tourists would have to use far larger boats and make many more trips into the manatees’ fragile habitat than they currently do.
   

答案是E,想问下为什么?选E不选B?

E说的是旅游对 manatees 生活的地方破坏更大。

A不行么？A说人们根本不想看，那不可能带来旅游收入，所以方案不成立。。。

gracezz

明白了，题干里面已经说了tourist interest is high...所以不能否定题干。。。。。无语ing...

B Recovery of the species would enable some hunting to continue without putting the manatees’ survival in jeopardy again. 这个怎么错了啊，难道是不相关选项？物种的恢复使得猎人能够继续打猎，同时不对MANATEES这个物种的存活造成威胁。

我觉得b里的some限制了范围

需要质疑方案能否成立，1 不能增加收入 2 伤害MM， E选项，伤害了MM，最主要的单词是 fragile habitat，说明了他们的habbit是脆弱的，所以选E
在方案题中，some 是无法质疑的，只要一部分就好了

不觉得B的前提就是文章的结论嘛（潜在的肯定了方案会成功-recovery），并在这个肯定之后，做出猜测MH还会被破坏。 所以这不是削弱选项。 就像我说： 看你吃这么多肯定会长胖啊，然后你说，我会运动瘦下去的。所以你同意了我的观点，你会瘦下去和我认为你长胖基本没有直接的逻辑关系。，起不到削弱。
