If the city starts requiring residents to sort the materials that they put out for recycling, then many residents will put more recyclables in with their regular garbage. This will result in more recyclables being buried in the city's landfill. However, because of the cost of having city workers do the sorting, the sanitation department will not stay within its budget unless the sorting requirement for residents is implemented.

Which one of the following statements logically follows from the information above?


(A) Most of the city's residents will continue to recycle even if a sorting requirement is implemented.

(B) If the city starts requiring residents to sort their recyclables, then all of the residents who continue to recycle will sort their recyclables.

(C) Implementing the sorting requirement would not cause the city's annual cost of sending garbage to its landfill to exceed its current annual cost of sorting recyclables.

(D) The amount of recyclables going to the city's landfill will increase if the sanitation department stays within its budget.

(E) If the city implements the sorting requirement, the sanitation department will stay within its budget.

Can anybody explain me this? I thought the answer should be E but it is D and I am not able to figure out why.

This is a tough question. It involves conditional reasoning.
Look:

Statement (1): Sorting (necessary condition) ---> Increase GR (suffient condition)

Statement (2): Increase GR (necessary condition) ----> Increase LR (suffient condition)

Statement (3): Budget (necessary condition) ---> Sorting (suffient condition)

Then, we can conclude

Budget --> Sorting --> Increase GR --> Increase LR

Therefore, we can conclude that Budget --> Increase LR. That's exactly what D says.

Instead, E says that Sorting --> Budget. That's not what we can deduce from the argument.

I hope it's useful.

Though it is mentioned in the argument : "because of the cost of having city workers do the sorting, the sanitation department will not stay within its budget", while drawing the logical inference, can we take it for granted that the city will definitely remain within its budget if the sorting workers are not recruited...Cant there be some other ways which could lead to the sanitation dept exceeding its budget even without the implementation of sorting workers....

This is the reason I left D

I think ....I somewhat understood this!

So if Segregation by residents is implemented,then residents would lazily put the Recyclables too in the regular Garbage .

The regular garbage segregation at the land fill will cost heavily for the department of it's done by the workers at the landfill. so, because of this Segregation by residents needs to be implemented.

And if the segregation of the Recyclables by the residents is implemented,then naturally residents will put all of it in Regular Garbage and that would increase the landfill. that's what option D states and correctly follows.
