Hello experts
I have doubt in the following
OG question ( though I read reply on some websites I am not convinced with it )-
Last year all refuse collected by Shelbyville city services was incinerated. This incineration generated a large
quantity of residual ash. ln 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.
Correct answer is option D but why is A not an assumption . What if the amount of refuse that has been separated for recycling is incinerated , will it not add to the residual ash.
Thanks
