When we do these Determine the Function questions, the most important thing to figure out first is "what's the main conclusion?"
You didn't mention what you thought the conclusion was, so take a second to look back at the argument and try to make that determination.
....
The main conclusion here, the suggestion the author is endorsing, is "The current voluntary system is to be preferred".
Why? What's his premise?
"Because it costs about the same as the nonvoluntary system but doesn't create as much resentment"
The keyword that helps show me the conclusion and the premise is the word "because". Any idea that comes after "because" or "since" is a premise. Whatever that idea is supposed to be supporting is a conclusion.
Note, this comes in two interchangeable forms:
"Because it costs about the same and causes less resentment, the voluntary system is to be preferred"
"The voluntary system is to be preferred, because it costs about the same and causes less resentment"
Anyhoo, knowing confidently that our conclusion is
"The voluntary system is preferred", let's ask ourselves if the first sentence is a premise, i.e., does the 1st sentence give us a reason to believe we should prefer the voluntary system?:
The town wouldn't need to spend as much money removing trash if everyone sorted their own garbage.
therefore
The voluntary system is preferred .... ???
Does this 1st idea support the conclusion? It doesn't sound like it to me.
If the town would save money by having everyone sort their own garbage, shouldn't we require everyone to sort their own garbage?
That's the "nonvoluntary system" the argument refers to.
The author is implictly arguing against requiring everyone to sort their own garbage.
The author acknowledges that a benefit of that idea is that it would incite some people to sort their garbage, but the author thinks that a bigger detriment to that idea is that many people would refuse to comply and resent it. (note the common form: WHILE I concede to my opponent X, I still think that Y is more important.)
Hence, the author concludes that we should stick with the voluntary system.
In the language of (B), "the editorial defends the practice of the voluntary system as preferable". Meanwhile, the 1st sentence, which really supports using the nonvoluntary system is described as "a fact that lends some support to an alternative".
You mentioned that you preferred (D) because it was expressed clearly and felt more safe. You should realize that the test writers know that --- that's what helps make this an appealing trap answer on a tough question. The fact that (B) is worded in a deliberately complicated fashion doesn't guarantee it's the correct answer, but you should realize that the test writers often use confusing phrasing in the correct answer (to hard questions) in order to make them less appealing to the masses.
Also, you should realize that in Main Conclusion and Determine the Function questions, the argument often refers either explicitly or implicitly to an opposing position. (You'll see linguistic cues such as "but/yet/however" to indicate the author disagreeing with some position. And you'll see "despite/while/although" when the author is saying "Although I grant my opponent this point, THIS is what I think is more important").
Be prepared and willing to read the argument multiple times in order to be sure you've differentiated the author's position and his premise vs. some opposing position and its premise.
I hope this helps. Let me know if you have further questions.
