GWD TN-5 28 看了以前帖子没解决问题，求指教

Environmentalist:  The use of snowmobiles in the vast park north of Milville create sun acceptable levels of air pollution and should be banned.
Milville business spokesperson:  Snowmobiling brings many out-of-towners to Milville  in winter months, to the great financial benefit of many local residents.  So, economics dictate that we put up with the pollution.
Environmentalist: I disagree:  A great many cross-country skiers are now kept from visiting Milville by the noise and pollution that snowmobiles generate.
Environmentalist responds to the business spokesperson by doing which of the following?
A.    Challenging an assumption that certain desirable outcome can derive from only one set of circumstances
B.    Challenging an assumption that certain desirable outcome is outweighed by negative aspects associated with producing that outcome
C.    Maintaining that the benefit that the spokesperson desires could be achieved in greater degree by a different means
D.    Claiming that the spokesperson is deliberately misrepresenting the environmentalist’s position in order to be better able to attack it
E.    Denying that an effect that the spokesperson presents as having benefited a certain group of people actually benefited those people

答案选E，我选的B...
看以前的帖子解释说B中是说正面效果>负面效果，可是be outweighed by是得不偿失的意思啊？
也就是说B其实说的是desirable outcome是得不偿失的，是负面>正面的呀...这样不对吗？
关于E...我觉得它错是因为没有说清楚a certain group of people 和those people这两个指代本身就搞不清楚是怎么个回事
或者说是我自己没有搞明白是怎么个回事....

请各位xdjm不吝赐教

但是certain也有 （不提及细节时用）某事、某种、某人的意思啊，不一定表示确定的~~

B选项说反了吧。。。enviromentalist 应该是同意负面效应大于正面效应，b却说environmentalist 反对负面大于正面  所以选E

B.    Challenging an assumption that certain desirable outcome is outweighed by negative aspects associated with producing that outcome 质疑一种假设，这种假设是“产生正面结果时附带生出了负面结果，这负面效应大于正面效应”提干不是比较正面负面哪个效应更大，而是说带来了负面效应，根本没有正面效应。

“a certain group of people 和those people”指的是“many local residents”，
E的意思是发言人说能够为特定人群（当地居民）带来（经济利益）好处，环境学家指出这不可能（因为很多人因为污染已经不来滑雪了）

Challenging an assumption (that certain desirable outcome is outweighed by negative aspects associated with producing that outcome)
挑战一种假设（随之而来的负面效应胜过了正面效应）。
ls说题目中没有正面效应，我认为是错误的。
正面效应指的是：snowmobiles吸引外资，带来great financial benefit，这些benefit可以compensate pollution
负面效应指的是：snowmobiles造成的noise and pollution，实际上导致了外资不愿意进驻M。
负面效应胜过了正面效应正是environmentalist 反驳spokesperson的方法，而B选项前面还有challenging an assumption，恰好说反了。

这道题在 http://gmatclub.com/forum/environmentalist-the-use-of-snowmobiles-in-the-vast-park-24740.html 上面有讨论，国外论坛给的答案是B，我选的也是B。 E错在那个spokesman说的受益群体是当地居民，而不是滑雪爱好者。而环境学家口中说的是滑雪爱好者

Challenging an assumption that certain desirable outcome is outweighed by negative aspects associated with producing that outcome

this choice means the environmentalist challenges SCIENTIST's assumption which states that harm outweighs benefit. However, notice that it is the environmentalist's view that harm outweighs benefit => reversed

E is right because S argues more visitors benefit ppl financially, however, the countereffect to such benefits is fewer skier visits => less income for ppl. => overall no benefit

原文中环境学家说的是滑雪爱好者，没错，可是这并不是指受益者就是滑雪爱好者啊，环境学家是说因为滑雪爱好者的离开，使得原本受益者的当地居民不再受益（financial benefits），这不就是在否定spokesperson的说法，“snowmobile原本是为了给当地居民带来好处的，目前也确实带来了好处”的这一说法吗？
E是正确的啊。
