All you have to do is find it and do it. (Picure below shows how it look like) You have to have 100% to get rewarded.
The questions they give are random but all are the same five question.
You need to know which answers go to which.
◾Julia & Jack are compulsive liars
◾Coffee is also D: Psychoactive
◾The monkey is a Lion-Tailed Macaque
◾The bridge is located in Cologne
◾Carolina is not a forename
