I also edited the wiki and added the answers there:

...and removed it again, so stupid mods wont actually delete it :-)

Regarding the quiz: there is a mistake in the patch notes, Quiz answers only give 2, not 5. Regardless whether the answer was right or wrong.
Which makes sense, you need 40 Minutes for a quiz answer, which gives 2 drops (or whatever that is...) and within the threads you get 5 drops, but you need 100 minutes for each.
...100/5 == 20 == 40/2.
