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
我的理解如下:
C 今年垃圾回收将含有相当大的比例的可循环材料,与去年相比。无关
E今年总的垃圾数量将不比去年多。无关
A 从可循环垃圾中被分离出来的材料将不会被焚烧。??
B从垃圾中分离可循环垃圾将会花费去年残渣处理的一半成本。??
D.今年垃圾的焚烧不比去年多产生残渣。??
看着ABD都有道理。请赐教,谢谢! |
