Materials to start a striving civilization
If I am in charge of a scavenger hunt, I will know where to find the locations of the materials necessary to survive. There are plenty of people who are capable of doing so as well, but it'd be amusing to see those who could provide help and actually maintain life with limited items that they found. What makes it even more interesting is that they will have to decide what people need to live on. This will show their cognitive memory of life's necessities. This shows not only who is the most skilled but who is most intelligent. Brains and brawn would be required for the adventure.
