48. If the county continues to collect residential trash atcurrent levels, landfills will soon be overflowing andparkland will need to be used in order to create morespace. Charging each household a fee for each poundof trash it puts out for collection will induce residents

to reduce the amount of trash they create; this chargewill therefore protect the remaining county parkland.

Which of the following is an assumption made indrawing the conclusion above?

(A) Residents will reduce the amount of trash theyput out for collection by reducing the number ofproducts they buy.

(B) The collection fee will not significantly affect thepurchasing power of most residents, even iftheir households do not reduce the amount oftrash they put out.

(C) The collection fee will not induce residents todump their trash in the parklands illegally.

(D) The beauty of county parkland is an importantissue for most ofthe county’s residents.

(E) Landfills outside the county’s borders could beused as dumping sites for the county’s trash.

这道题上，我是纠结于为什么A选项不对。"因为收费就会减少排放，所以保护了parkland"---我觉得既然A 减少了垃圾的排放量，亦支持了原文。
所以一直没有找到可以说服自己的原因。求助大家耐心讲解。。。。谢谢！！

此题型好像不是support,而是“哪种可能性能在原文中体现”

A 中的观点说 by reducing the number ofproducts they buy.让我觉得有点问题不选
B 不解释
D表达了观点主观了不选
E也是原文并未体现outside the county’s borders

c 收了费人就不会再乱倒垃圾了 " illegally“ 的出现也没有违背原文的意思

这是我小小的想法希望能给你点帮助

谢谢Jasminexia！！！！
我貌似把assumption题看成support题了。。。，A中 by reducing the number ofproducts they buy我也觉得很有问题，虽然用技巧可以排除，但我还是想复习是精益求精一点。。是不是可以认为 by reducing the number of products they buy这个无法作为原文的假设而排除？

哦！又或者我可不可以这样想，原文的逻辑链是：收费--减少垃圾产生--保护了parkland. 只有C选项最完整的补充了其中的假设，就是不仅减少垃圾排放，居民也不会illegally的扔垃圾到parkland，这样才真正达到结论。而A选项并不能起到假设作用，如果说假设人们通过少买东西而少垃圾，并不能就保证垃圾一定就扔在legal的地方。
