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?
OG12 107 107. 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. (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 services this year will be no greater than that collected last year. 这是一道逻辑题,但是因为选项中no more... than... 这个结构把我搞混了,在语法上来看no more。。。than。。。是表示两者都不,和。。。一样不,那么按照这个理解的话就是今年和去年焚烧垃圾都不会产生焚烧垃圾灰烬了。。。
if half of the collection is recyclable, ash after incineration will be the half of last year. (preassume that the material generates same amout of residual ash as last year)
