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. A great many cross-country skiers are now kept from visiting Milville by the noise and pollution that snowmobiles generate.
B. Not all of the people who go snowmobiling in the vicinity of Milville are from out of town.
C. Snowmobiles, because they run on two-cycle engines, emit greater amounts of hydrocarbons and particulate matter than cars do.
D. Industrial pollution in Milville has been significantly reduced in the past few years without any adverse effect on the town’s economy.
E. Many Milville residents object to having to pay fees for recreational use of the park in the winter.
如题，我选的是E，因为我觉得E直接反驳Milville Business Spokesperson的economic problem的观点，但是答案是A，然后我看了一下，好吧，A我也认为对，那么就出现两个对！谁能解释下E？多谢作者: 疯婆子颠三 时间: 2013-10-5 17:55
我昨晚也做了这题，也错了。。。。
后来分析了一下，答案确实是A。M公司的发言人说雪地摩托能够在冬天时吸引很多来自其它镇的人来这里，从而带来经济效益，而答案A直接就否定了这一点，因为冬天来滑雪的人不喜欢雪地摩托车带来的污染，反而不来了，经济效益反而下降。至于E在这里应该确实是否定了题目中的ADDITIONAL PREMISE，但是可以说是没切中要害吧，如果从BEST CHOICE的角度来看的话。。。
不知道这样分析对不对哈。。。。。
