Economist: The most economically efficient way to reduce emissions of air pollutants is to tax them in proportion to the damage they are likely to cause. But in Country Y, many serious pollutants are untaxed and unregulated, and policy makers strongly oppose new taxes. Therefore, the best way to achieve a reduction in air pollutant emissions in Country Y would be to institute fixed upper limits on them.Which of the following is an assumption of the economists argument?

Which of the following is an assumption of the economist’s argument?

A、Policy makers in Country Y oppose all new taxes equally strongly, regardless of any benefits they may provide.
B、Country Y’s air pollutant emissions would not fall significantly if they were taxed in proportion to the damage they are likely to cause.
C、Policy makers in Country Y strongly favor reductions in air pollutant emissions.
D、Country Y’s policy makers believe that air pollutant emissions should be reduced with maximum economic efficiency.
E、Policy makers in Country Y do not oppose setting fixed upper limits on air pollutant emissions as strongly as they oppose new taxes.

专业教师答疑

问题：A为什么不对呀？取非的话，有benefits的时候policy maker不反对tax，不久可以加强tax的可实行性吗？这样的话tax不就还是最efficient的吗？这道题的的P是policy maker反对tax C是limits最有效我找的是对的嘛，谢谢老师的解查看答疑

问题：请唐老师解析一下。我先读题，然后定位最后一句：达成在Y市的空气污染物排放量的减少的最优方法是对排放量设上限。看5个选项，我觉得B和最后一句最相关，提到了污染排放，而且回答的很直接。E选项policy maker和最后1句话感觉不相关，仅出现一个比较关系，整体感觉牵强查看答疑

问题：请问英吉老师，不太理解og中对选项的解释，觉得对此题解释很复杂。其实对于逻辑题的选项，我们只分析有关无关，是加强还是削弱就足够能解题了是吗？一般题目不必再去细抠更具体的解释了吧?谢谢。查看答疑

问题：为什么c，d不对查看答疑

问题：为什么这题B不对？查看答疑

问题：选对了，请老师帮忙翻译E 查看答疑

问题：这道题E的逻辑是什么呢？？没弄懂查看答疑
