Some questions concerning part 2 of the exercise:
1. could one assume elves are called up randomly from the different groups (i.e., one could not quarantee order and in worst case all elves from one group could be called before elves from the other groups are called)?
2. do the elves from the same group as called-up elf learn about the cookie type, which was in elf's box, after he said his answer, or they hear only the answer of the elf, but do not know, whether his answer was correct?
