885 test D 12 企业减少与污染

dandan74

我问一个问题：如果把B改为：
The economic decline of the state "cannot " be attributed to the effects of the Clean Air Act.
是不是可以成为正确答案呢？

不论the effects of the Clean Air Act是什莫，如果可以导致the economic decline再加上原题的premise不正可以说明可以减少污染马？

the effects of the Clean Air Act -> the economic decline -> decline of the pollution.
我的意思是说，原来的argument is based on an assumption that Clean Air act 不会导致 the economic decline从而间接的导致 decline of the pollution. 我记得考过类似的题。
