City’s Claim: The new weekly recycling program will be more cost-effective because collecting more recyclables leads to higher revenue.
Editor’s Counterargument: The total volume of recyclables won’t increase—it will just be spread out over more frequent pickups. Therefore, the city’s claim is absurd.
To weaken the editor’s argument, we need to show that the total volume of recyclables might actually increase under the new system.
Why (D) is Correct
"(D) A weekly schedule for recyclables pickup is substantially easier for people to follow and adhere to than is a schedule of pickups every other week."
If people find the new schedule easier to follow, they might recycle more often instead of throwing recyclables into regular trash when they miss a pickup.
This would increase the total volume of recyclables collected, which directly weakens the editor’s argument that the volume will remain the same.
Why the Other Choices Are Wrong
(A) The cost of collecting and disposing of general trash has been less than the cost of collecting and disposing of recyclables, and this is still likely to be the case under the new recycling program.
Irrelevant. The argument is about whether the new program increases recyclables collected, not about how recyclables compare to general trash in cost.
(B) Even if the volume of collected recyclables increases, that increase might not be enough to make the recycling program cost effective.
This actually strengthens the editor’s argument by suggesting that even if more recyclables are collected, the program might still not be cost-effective.
The editor is saying the volume won’t increase, so we need to attack that assumption, not question cost-effectiveness.
(C) Because the volume of recyclables people accumulate during a week is less than what they accumulate during two weeks, the city expects a recyclables pickup to take less time under the new program.
Irrelevant. The argument is about whether people will recycle more, not about how long pickup takes.
(E) Because of the increase in the number of pickups under the new program, the amount charged by the contractor that collects the city's recyclables will increase significantly.
This actually strengthens the editor’s argument!
If costs increase, it supports the idea that the new program won’t be more cost-effective.
