OG12-CR-48.
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 create 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 create; this charge will therefore protect the remaining county parkland.

Which of the following is an assumption made in drawing the conclusion above?

(A)Residents willreducethe amountoftrashthey put out forcollection by reducing the numberof products
they buy.

(B)The collection fee willnot significantly affect thepurchasing powerof mostresidents, evenif their households donotreducetheamount oftrash theyput out.

(C)Thecollection fee willnot induce residentstodump theirtrash in theparklands illegally.

(D)The beauty of county parklandisan importantissue for most of the county'sresidents.

(E)Landfills outside the county's borders could beuse d asdumping sites for thecounty'strash.

Answer is C
but I want to know why A is not right.

题目问假设。
人们通过少买东西来少扔东西。和征税保护parkland没啥关系呀。因为题目只关心人们是不是少扔，至于买不买，题目未涉及

assumption 是必要条件。条件不成立则结论不成立。谁说少买东西就是少扔垃圾的必要条件了？你从定义出发马上就排除了。

而按照官方做法，答案取非之后削弱文章结论。取非A，变成了Residents will not reduce the amount of trash they put out for collection by reducing the numberof products
they buy。根本就不是削弱。排除。

当然考试的时候肯定直接想最方便。

A选项，OG里面的解释是，政府开始收费，A这种现象或多或少都有可能发生。但万一人们可能还会像收费之前那样，买同样多的东西，只不过用的更久甚至循环利用，那样子trash也同样会变少。这样来说，trash少不少，跟买东西的多少没有必然关系，因为还有人们使用的问题，那么也跟收不收费没有太大关系。

这里有个感触，一般正确的选项在五个当中，总是最直接最有力的，那么这种选项往往会提到argument里的关键词。像这篇argument，结论是charge——reduce trash——protect the remaining parkland. C选项里就都提到了。
