标题: og12 逻辑 -107 坐等回复。。
Last year all refuse collected by Shelbyville city services was incinerated.This incineration generated a large quantity of residue 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.

E.The total quantity of refuse collected by Shelbyville city services this year will be no greater than that collected last year
.[D]
虽然答案是D，我也觉得选D更好，可是我感觉D好像也有点问题啊。D说今年所焚烧的垃圾，每车垃圾产生的灰烬不比去年多，但它并没总的不能循环的垃圾数量的多少，假如说要焚烧的垃圾量比去年多，虽然每车的灰烬量少，但不能保证总的灰烬量少啊。

这个到底是怎么理解呢？我也不知道我理解对了没？

我认为循环垃圾是不需要焚烧的吧，循环的么，像纸啊，玻璃啊什么不是可以再做成新产品么。它题目的意思是通过垃圾分类，从而使得焚烧垃圾的总数量减半。之后又说垃圾车的数量减半，那自然每辆车的不能增加

我感觉这题的题目主要是在说垃圾的灰烬吧，想尽量减轻垃圾灰烬。题目说通过把每车垃圾容量（truckloads）减半来控制垃圾灰烬。只有D选项里面提到了垃圾的灰烬并且同时提到了truckloads，所以D答案最好。

ls，谢谢啦。。不过我刚看了，明白了。
但是题目没说车数量的减少，说的是the number of truckloads of refuse.是说垃圾量，而不是垃圾车的数量。。
题目说要垃圾灰减小到一半，先让垃圾数量减少到一半。
所需的前提是每车的垃圾灰不会不以前多。

premise: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.
conclusion: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.
gap:The refuse incinerated this year will generate no more residue ash per truckload incinerated than did the refuse incinerated last year.

Hope that helps

(C) Refuse collected by cityservices will contain a larger proportion of recyclable materials this yearthan it did last year.错误，上一年也有containrecyclable垃圾，只是一起烧了，没有分出来而已。

(D) The refuse incinerated this yearwill generate no more residual ash per truckload incinerated than did therefuse incinerated last year. 正确，今年垃圾总量减少，卡车数量不变，每车垃圾自然就减少了。D

(E)The total quantity of refuse collected by Shelbyville city services this yearwill be no

greaterthan that collected last year. 和总量没有关系，关键的是今年：垃圾里含有的不可回收的垃圾 vs 去年：垃圾总量的对比
