标题: GWD,6-4.关于“抬杠”－－正确选项直接否定原文的内容。求大神帮助
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.

这道题选E ,楼主本来选A，可是老师解答说，原文说“tourist interest is high”，而A选项说“many tourists are

uninterested..”直接抬杠，所以错。

然后又遇到了这道题：

In the past the country of Siduria has relied heavily on imported oil. Siduria recently implemented a program to convert heating systems from oil to natural gas. Siduria already produces more natural gas each year than it burns, and oil production in Sidurian oil fields is increasing at a steady pace. If these trends in fuel production and usage continue, therefore, Sidurian reliance on foreign sources for fuel should decline soon.

Which of the following is an assumption on which the argument depends?

A.In Siduria the rate of fuel consumption is rising no more quickly than the rate of fuel production.

Domestic production of natural gas is rising faster than is domestic production of oil in Siduria.

No fuel other than natural gas is expected to be used as a replacement for oil in Siduria.

Buildings cannot be heated by solar energy rather than by oil or natural gas.

All new homes that are being built will have natural-gas-burning heating systems.

答案是A。我就蒙了，因为原文说了“if these trends in fuel production and usage continue,”那A选项说“fuel consumption is rising no more quickly than fulel production” LZ感觉这个也是抬杠。。可却是正确选项，求牛牛解释！
