Last year all refuse collected by Shelbyville city services was incinerated. This incineration generated a large quantity of residual ash. In order to reduce the amount of residual 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 residual 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 residual ash per truckload incinerated than did the refuse incinerated last year.
(E) The total quantity of refuse collected by Shelbyville city service's this year will be no greater than that collected last year.

去年，S城回收的所有垃圾都被焚烧。焚烧会产生大量的灰烬。为了减少灰烬的数量至去年的灰烬总量的一半，S城准备调整其收集项目。今年，城市公共服务区分足够的垃圾以便回收，来减少待焚烧垃圾的总量至去年焚烧垃圾总量的一半。

简单说就是：去年焚烧垃圾，产生很多灰烬(ash). 为了使得灰烬减半，今年准备调整，将焚烧的垃圾总量减半。

希望可以帮到你。这是OG的原题的。
