Last year all refuse [C1] collected by Shelbyville city services was incinerated. This incineration generated a large quantity of residue [C2] ash. In order to reduce the amount of residue ash Shelbyville generates this year to half of last year’s total, the city has revamped its collection program. This year city services will separate for recycling enough refuse to reduce the number of truckloads of refuse to be incinerated to half of last year’s number.
Which of the following is required for the revamped collection program to achieve its aim?
A. This year, no materials that city services could separate for recycling will be incinerated.
B. Separating recyclable materials from materials to be incinerated will cost Shelbyville less than half what it cost last year to dispose of the residue ash.
C. Refuse collected by city services will contain a larger proportion of recyclable materials this year than it did last year.
D. The refuse incinerated this year will generate no more residue ash per truckload incinerated than did the refuse incinerated last year.[C3]
E. The total quantity of refuse collected by Shelbyville city services this year will be no greater than that collected last year.
[C1](N.)waste material that has been thrown away
[C2]a substance that remains on a surface, in a container etc and cannot be removed easily, or that remains after a chemical process
[C3]Correct. The program is to reduce the number of truckloads of refuse to be incinerated to half of last year’s number in order to reduce the amount of residue ash generated this year to half of last year’s total. Therefore, we must prove that the reduced refuse this year incinerated will generate less residue ash per truckload than the refuse incinerated last year.
我跟你一样，坚决觉得给出的答案D是错误的，C是对的
D是迷惑选项
原文先说REFUSE可以产生很多RESIDE，然后说In order to reduce the amount of residue ash Shelbyville generates this year to half of last year’s total，就采取了一个计划，即第一道工序里先把REFUSE循环利用，这样REFUSE/TRUCK就低了。题目问这个计划到底能不能被实施？]
D说的是计划采取后的效果，REFUSE产生的RESIDUE变少了，但是并没有从推理过程去分析。
我认为答案是C,理由有二：一是用我的傻瓜方法最后一句冒出truckload出现，则答案应该解释一下truckload,二是truckload 数量应该不变，若变多了，则缩减一半也不能达到原来的效果
本来这道我也错了,题意没太懂,不过看了qianrene分析的题目
确信应该选D的
偶的一点愚见:
题目是说: 目的是减少RA(residue ash)到一半,措施是增加recycle的量,使得运去烧的truckloads的数量下降到一半
D说的是每辆的truckload产生RA的量不会比去年多
数量减了一半,每个的量又不会多,所以目标肯定能达到
C才是在逻辑思路外的~

看看原文最后的推理，说的是通过循环这种方法才达到目的，当然最后问题也要着重在这个方法This year city services will separate for recycling enough refuse to reduce the number of truckloads of refuse
采取了这个方法后当然会产生D的结论“D说的是REFUSE产生RESIDUE/每辆的truckload的量不会比去年多”没有把重点放在政府采取的方法上，所以不对
qianrene：我觉得这道题是问必要条件，这也许是造成我们分歧的主要一点
D取非结论肯定不成立，所以是必要条件，我想这点你应该是承认的
对于C，Refuse collected by city services will contain a larger proportion of recyclable materials this year than it did last year.，
larger proportion是个很模糊的概念，到底是大多少呢？取非是肯定不成立的，这就是我的思路

有道理，C看上去很美，但是个人觉得比去年可循环的也可以很少，文章说了政府把部门拆了，且能分出足够的recycling XXX，好象是这个意思，我们可以去质疑这点么？
The answer is C
The aim is reduce the number of truckloads of refuse to be incinerated to half of last year’s number
So, D is focusing on each truckload, not the number of truckloads.
... S.S
Agree with LS, "This year city services will separate for recycling enough refuse to
reduce the number of truckloads of refuse to be incinerated to half of last year’s number. "
如果TRUCKLOADS减少了,但是每TRUCKLOADS 的RESIDUAL ASH却增加的话,那么总量还是一样的,就达不到计划的原目的.
The answer is C
The aim is reduce the number of truckloads of refuse to be incinerated to half of last year’s number
So, D is focusing on each truckload, not the number of truckloads.
C根本就不相关。题目说的是“需要焚烧的垃圾”的残渣要减半。C却去讨论“可再生垃圾”和“需要焚烧的垃圾”的比例。请注意，比例跟数量是不一样的。
D说每卡车“需要焚烧的垃圾”所产生的残渣比去年的少。再加上题目最后一句话说要把卡车数减半。把这两个数乘起来，就得到总的残渣量小于去年的量的一半。这正是政府希望达到的目标。所以D是正确的！
D是正确的
题目的推理是:通过减少车载的数量来达到减少一半灰尘的目的.
而C选项和车载的数量无关,不能说明车载数量对减少灰尘的影响,只是说明了另一无关原因:增加了可回收废物的比率对灰尘的影响,所以是无关选项
做逻辑题不能脱离原文,不知道理解对不对,欢迎讨论
文章结尾说通过recycle减少要焚烧垃圾的truckloads到去年的一半，以减少产生的ash到去年的一半。
产生的ash的量 = number of 要焚烧垃圾的truckloads * 每truckloads产生的ash量
number of 要焚烧垃圾的truckloads 已经减少到去年的一半了，要想产生的ash的总量为去年的一半，必须要求就是per truckloads 产生的ash量不会比去年多。否则，每truckloads要焚烧的垃圾产生的垃圾量为去年的100倍，减少一半truckloads也无济于事
