Not too sure about this, but isn't 17. a) Because they have the same molarity, but hcl is stronger than than acetic?

Nah it's not, it's like a titration. As long as you have the same number of moles of acetic and HCl (cos theyre both monoprotic), the same volume of NaOH is required. (like how the same volume of NaOH is required to reach equivalence point of HCl and Acetic, both monoprotic)

13 has to be D. If we accept the premise that the writing on the cup means nothing and is simply a trick, then the cup could be made from either PE or polystyrene (polystyrene cups are very popular). It would hence seem that this would mean A and B are correct, which cannot be the case. However, if we think logically and use the writing on the cup, it can be seen that ONLY cellulose is a renewable creation made from plants. Hence, D is the correct answer.

13 also asks what polymer was most likely to have been used in the manufacture of the cup, rather than what polymer the cup is likely to be made of. While it could be MADE of polyethylene or polystyrene, cellulose is most likely the polymer used to manufacture the cup. That's how I interpreted the question at least.
