Far off in the heart of the Rocky Mountains, there is a place called Camp Curatos. No, it is not named after some random tribe; rather, it is a camp dedicated to curing teens of all ages of bad and childish habits. Recently, the camp advisors have taken on five new challenges (3 boys - Mark, Joseph, and Kev; and 2 girls - Selene and Ariadne). However, in their files, the advisors seem to have gotten a few facts mixed up about these five teens! Can you help them piece together the facts?

1. The 5 teens are Joseph, the 12-year-old, the pencil-snapper, the procrastinator, and the one rewarded with ice cream.

2. Selene is one year younger than the procrastinator.

3. The pencil-snapper left after the shortest amount of time; he was rewarded with a Chevy (which he was able to drive).

4. Ariadne is not the oldest; however, she did take the longest time to leave Camp Curatos.

5. The 15-year-old took 23 days to be cured of his nail-chewing habit.

6. Mark received $20; CDs were sent to Joseph.

7. The 12-year-old spent 3 weeks in camp, but it was well worth his time, for he could now pay attention in class without fidgeting.
