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

 这道题答案是E,但是我对B总存在疑虑，请大家帮帮我，谢谢

can anyone help me?

第2题发言人的assumption是认为expected outcome可以overweight negative aspects，原因是新举措而被吸引前来的人。然而环境学家没有针对这一人群进行反驳，他另辟奚径地针对由于新举措而不愿意前来的人，从而质疑新举措的执行效果，所以B有缺陷。
