Solution to Problem 6: "Cartoon Sequence"
Panel C is the only one in which the hat is destroyed, and D has the hat being destroyed, so these are the last two figures. The man was asleep only in panel B and is being awaken in Panel F, so those are the first two panels. A shows the man aiming the gun right before it was fired in D, so that is fourth. The sequence is BFEADC.
Comments: I'm shocked that 23% of people didn't attempt this one. I think it was the easiest points in the contest.
