I am unclear of what can be included in center 3 for Q23

@Baylor, The question asks us if Center 1 is the only recycling center than recycles wood, which of the following could be a complete list of materials that one of the recycling centers recycles? We can infer that: Center 1 must recycle wood newsprint glass Center 2 must recycle newspaper glass Center 3 must recycle plastic tin Center 3 could also recycle newsprint thus either: plastic tin plastic tin newsprint are both possible scenarios, so either one could be the correct answer choice for a "could be true" question.
