if the county continues to collect residential trash at current levels, landfills will soon be overflowing and parkland will need to be used in order to creat more space. charging each household a fee for each pound of trash it puts out for collection will induce residents to reduce the amount of trash they creat; this charge will therefore protect the remaining county parkland.
A. the collection fee will not induce residents to dump their trash in the parkland illegally.
B. landfills outside the county's borders could be used as dumping sites for the county's trash.

为什么选A不选B啊？？？

这题问的是削弱吗？
不管怎么样，结论是this charge will therefore protect the remaining county parkland。关心的是parkland
B中的landfills outside the county 明显无关

如果削弱的话，那么A就很好，就算有这个fee人们还是会illegally往parkland扔垃圾，那么题目的结论就起不到效果，这个fee没有起到保护parkland的作用

assumption题！不好意思忘写出来了额

小比熊 · 发表于 2011-6-20 09:58:03

就因为是assumption题，应该选一个加强选项啊！答案里的not很是让人费解。。。

那就对啦，A取非可以削弱，所以是个必要的假设，B依然无关
