Please explain

Michelle, since ONLY ONE center recycles plastic, and C1 recycles the same as C2, C3 has to be the one recycling plastic.

I believe there are two correct answers here. If Center 2 recycles three materials it MUST be N, W, and G (any other combination would break one of the rules...)....that being said Center 3 MUST recycle Plastic AND tin, therefore both C and D are correct...or am I missing something here?

There are never 2 rights answers on LSAT
Its a MUST BE question
it means that each wrong answer choice could be false (not necessarily true)

If c2 has 3 slots that means c1 has to have 3 slots. (rule #2)

hyp1:
c1: wng c2: wng c3: Pt
(P--->no g
so if c2 has 3 slots that means g is in c2 and c1 and p is in c3) Notice how c3 can have 2 slots instead of 3. This is a key deduction that can help debunk while N or W DO NOT have to be in slot 3.

hyp 2:
c1: tgn c2: tgn c3: Pwn
[so tin doenst have to be in center 3]

(Dont do a mistaken reversal in writing down the rules. Rule number 1 says that IF W--> N. It does not state that if N-->W. So N can be there without w).

Answer key A is incorrect because glass cant be in c3 with plastic as a combination of rule 3 and rule 2 forces glass to c2 and c1.

Answer key B is incorrect because newsprint doesnt necessarily have to be in c3. PT could fill c3 while wng fill in c2 and c3

Answer key C: is correct because in all of the hypotheticals plastic MUST be in c3.

Answer key D: is incorrect because tin could be in c2 and c1 while plastic sits with wn in c3.

Answer key E: is incorrect because w does not necessarily have to be in c3, as p and t can occupy c3 while wng occupy c2 and c1.


Overall, doing templates can really help in doing this question. Hypothetically, by combining rules 2 and 3 you can deduce that plastic MUST be in c3 without having to do templates.

Hope this helps.
Remember, on LSAT there are never two correct answers to the same question.

I had a question about this one. The phrasing of the question doesn't seem to state directly that all 5 materials must be recycled between the 3 centres. It seems that you could have a solution where only tin and glass (centre 1/2) and tin and plastic (centre 3) were recycled. I'm just wondering if you consider the wording of the question to necessitate that each material is recycled by at least 1 of the 3 plants. It didn't come up in any of these questions but I find LSAT phrasing confusing sometimes.


Also I know that you don't need this bit of information to answer the question since you know because of the rules that plastic has to be used exactly once and groups 1 and 2 will be identical.

Thanks

In one of the previous questions it was 1cwn 2wn 3tg
