Environmentalist: Snowmobiles in the park north of Milville create unacceptable levels of air pollution and should be banned.
Milville Business Spokesperson: Snowmobiling brings many out-of-towners to Milville in the winter months, to the great direct financial benefit of many local residents. In addition, the money the town collects in fees for the recreational use of the park indirectly benefits all Milville residents. So, it is basic economics for us to put up with the pollution.
Which of the following, if true, could best be used by the environmentalist to counter the business spokesperson's argument?
A great many cross-country skiers are now kept from visiting Milville by the noise and pollution that snowmobiles generate.
Not all of the people who go snowmobiling in the vicinity of Milville are from out of town.
Snowmobiles, because they run on two-cycle engines, emit greater amounts of hydrocarbons and particulate matter than cars do.
Industrial pollution in Milville has been significantly reduced in the past few years without any adverse effect on the town's economy.
Many Milville residents object to having to pay fees for recreational use of the park in the winter.
情景：摩托雪橇会产生很多排放。但是，由于摩托雪橇可能会带来很多经济收益，例如，这种活动会吸引来许多城镇之外的人来Milville游玩，另外，从这些娱乐设施中赚来的钱可以反过来回馈给Milville的居民。因此，经济原因可以让我们忍受污染。
推理：
前提：摩托雪橇会吸引来许多城镇之外的人来Milville游玩，另外，从这些娱乐设施中赚来的钱可以反过来回馈给Milville的居民
结论：经济原因可以让我们忍受污染
答案预估：
这些经济的优点和污染的缺点需要权衡。
选项分析：
A选项：Correct. 很多跨国的滑雪者现在由于噪音和污染已经不再来Milville了。由于污染可能影响到经济的发展，如果忽略污染问题Milville的经济状况可能出现危险，所以本选项反驳了“经济利益可以让我们暂时忽略污染的问题”这个结论。
B选项：并不是所有在Milville附近玩摩托雪橇的人都是外镇的人。不论是不是所有人都是外镇的，只要是有外镇的人在Milville附近玩摩托雪橇，那么就会给Milville带来经济利益。所以本选项不能反驳结论。
C选项：摩托雪橇，由于其是双引擎的，会释放出比汽车更多的碳氢化合物和一些特定物质。推理文段的结论是经济利益可以让我们忽略污染，而本选项讨论的是污染的情况如何，和结论无关。
D选项：在没有影响任何经济利益的前提下，Milville的工业污染逐年下降。本选项没有提到对于原文中的结论“经济利益可以让我们暂时忽略污染的问题”。可以排除。
E选项：许多Milville的居民反对在冬天付费入公园游玩。无论居民反对与否，只要经济利益还在，就不能反驳推理文段结论。

choice a,很多跨国的滑雪者现在由于噪音和污染已经不再来Milville了。 correct，雪地摩托带来的benefits被disadvantages所抵消了
d为什么不对，降低污染不会影响经济，但是第一个人的建议是ban-》直接就没有经济收益了，而不是减少污染，
B/E weaken 分别weaken reason1/2 没有A强
1.滑坡论证是因果，不是果因。
2.本题PC没抓住。仔细审题，结论句非常明显，就在So之后。经济原因忍受污染。那么A很明显就削弱了结论。
