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?

A)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.

B)Recovery of the species would enable some hunting to continue without putting the manatees’ survival in jeopardy again.

 C)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.

D)There would not be enough former manatee hunters to act as guides for all the tourists who want to see manatees.

E)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.

Answer:E

觉得E中缺少一个条件：many more trips into manatees' habitat would cause them endangered.虽然E中用了fragile这个词似乎有所解释，但是还是觉得是个GAP．现文中没有涉及habitat的问题，所以觉得这个选项无关，任何解释都为主观臆断

Mine:A(虽然觉得这个答案不象是ETS的风格）

open to discuss~

个人理解：

A是显然错的，很典型的错误，"Many tourists"不喜欢去看manatees不代表这个旅游业没前途，因为Many是个很虚无缥缈的词，如果它用"most"或者“99％”这样的词，才能说明这个行业没前途。。。

文章说要这个PLAN能够保证猎人改行后有good income，而且能保护manatees生存下去，这是解体点：

E说要想维持当前的收入，猎人要用更大的船，而且要去更多趟manatees那”脆弱”的生存环境。这意味着猎人首先得投资买大船啊，然后还要去更多趟，也就意味着花更多的时间啊，更多的钱和时间的投入，更大的风险，很难保证猎人的能有good income。而且“脆弱”一词貌似想说旅游的人多了manatees会被烦死...

其他几个错误比较明显...

但是E首先就给了个前提＂to maintain their current income",即当猎人们投入更多成本是为了达到这个目的，那么＂很难保证猎人能有good income＂就不成立了．

偶觉得关键在于fragile这个词，正如joyfit用的那个词＂貌似＂（用的好）是要说明manatee的生存会有问题．但仅仅是貌似啊！万一考到类似的题，我一定是把这个答案先给灭了的
