If Center 2 recycles three kinds of material, then which one of the following kinds of material must Center 3 recycle?

Question
The rule states that center 1 must recycle everything that center 2 recycles, but why does that mean center 1 cant recycle additional materials. As long as they also recycle the 3 materials from center 2, why can't center 1 additionally recycle plastic?
