大家来看看这条CR 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? - 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.
- Recovery of the species would enable some hunting to continue without putting the manatees’ survival in jeopardy again.
- 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.
- There would not be enough former manatee hunters to act as guides for all the tourists who want to see manatees.
- 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 我选A. 文章最后说因为这个游客怎样怎样和HUNTER怎样怎样所以可以PLAN有效.那么A是针对游客说的.所以我选A. 难道我思路错了?A削弱前提所以不对???
还有这题: Sonya: The government of Copeland is raising the cigarette tax. Copeland’s cigarette prices will still be reasonably low, so cigarette consumption will probably not be affected much. Consequently, government revenue from the tax will increase. Raoul: True, smoking is unlikely to decrease, because Copeland’s cigarette prices will still not be high. They will, however, no longer be the lowest in the region, so we might begin to see substantial illegal sales of smuggled cigarettes in Copeland. Raoul responds to Sonya’s argument by doing which of the following? A: Questioning the support for Sonya’s conclusion by distinguishing carefully between No change and no decrease B: calling Sonya’s conclusion into question by pointing to a possible effect of a certain change. C: Arguing that Sonya’s conclusion would be better supported if Sonya could cite a precedent for what she predicts will happen. D: showing that a cause that Sonya claims will be producing a certain effect is not the only cause that could produce that effect E: pointing out that a certain initiative is not bold enough to have the predicts it will have 我选了E,但是答案是B.不太明白.
