The correct answer is D, the recycling program is inconvenient.
The question is what problem is being addressed.
- The passage gives solutions to the problem, it says for example "residents should have the option of another drop-off location" but this isn't the problem, this is a solution.
- There is no mentioning of residents throwing recyclables in the trash and it says that collection should be picked up on the curb, however this is not the problem being addressed in the passage neither.
