I actually find complete and accurate easier than just "partial list" or "a list" -- this is what I do:
First, if I had a straight "which one of the following is an acceptable list" question, I look at my answer for that and see if I can eliminate any answers based off it for my complete list question.
Then, I look and see what variables the answer choices have in common, and which variable is the stand out. Say X is only in choices A and D, but Y is in answers A-E. So I know that Y has to be in the correct answer, no bother testing it.
Then, I try to create a hypothetical with answer X and Y (and anything else I want to fit in that's used frequently in the answer choices). If I am able to make a hypothetical with X, then I can eliminate any answer that doesn't have X. If not, then I can eliminate any answer that has X.
At this point hopefully you've noted trends during your creation of hypotheticals to eliminate the other answers as well. If not, test them individually to find out which one works.
If you have trouble with this type of question, since it can take time, I'd advise you skip it until you've finished all the other ones for the game.
