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，但是B为什么不对呢？是因为B不是assumption么？

B说，E驳斥M的理由是，M错误的认为雪地车带来的收入>带来的环境污染，正面>负面

但是M没有比较正面和负面的影响，只是说有了雪地车，旅游收入会增加，会给当地带来经济收入，环境污染可以先不管，即只要有正面影响，就可以先不管负面影响，不管负面影响有多大，所以B不对。

E选项怎么理解啊，having benefited a certain group of people actually benefited those people？

E.    Denying that an effect （that the spokesperson presents as having benefited a certain group of people） actually benefited those people


把括号里的省略读一遍就懂了。
括号里是解释effect的

那those指的是什么呢？

B说反了吧
假设是certain desirable outcome is outweighed by negative aspects associated with producing that outcome：负面超过正面结果，然后又challenge这个假设，就变成了支持正面超过负面结果，反了。（环保学家应该是支持负面结果更多的）
