The video explanation goes a little bit too fast on this one for me is there anyone else could get like a more detailed answer of all the scenarios for this question

Hi CJLEAL,
For this question, we should try to make some deductions about plastic before we make 5 scenarios- as that can get very time consuming.
We know that only one of the centers is able to recycle plastic but rule two tells us that any material at center two is also at center 1. That means that if plastic is recycled at center 2, it would also be recycled at 1, which is not allowed- so plastic cannot be recycled at center 2. We can use this to eliminate C and E.
We then need to figure out if plastic can be in center 1, 3, or both. we could construct a scenario where
1: P, W, N
2: W, N
3: G, T
and one where
1: G, W, N
2: W, N
3: P, T
Since it looks like P can go in both, we can choose D.
