OG13-109/OG12-107
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.
(D) The refuse incinerated this year will generate no more residual ash per truckload incinerated than did the refuse incinerated last year.
OA: D
纠结A选项,我认为A也是program达到目标的assumption,因为如果回收的东西也被焚烧的话,那么也会产生很多ash啊,那么也不能达成program的目标了吧~
谢谢各位CDers~~ |
