1.25. A man is lying, dead, face down in the desert wearing a backpack. (This is different from #1.24, #2.2, and #2.12.)
1.25 answer: He jumped out of an airplane, but his parachute failed to open. Minor variant wording (from Joe Kincaid): he's on a mountain trail instead of in a desert. Minor variant wording (from Mike Reymond): he's got a ring in his hand (it came off of the ripcord).
1.25 variant answer: The man was let loose in the desert with a pack full of poisoned food. He knows it's poisoned, and doesn't eat it -- he dies of hunger. (from Mike Neergaard)
1.25a. Silly variant: same problem statement, with the addition that one of the man's shoelaces is untied.
1.25a answer: He pulled his shoelace instead of the ripcord.
1.25b. Variant wording: A man with a pack on his back enters a field and dies. (from David Norman)
1.25b answer: Same as #1.25.
1.25c. Variant wording: A dead man lies in front of the post office; next to him is a parcel. (CB)
1.25c answer: Same as #1.25. Can a parachute be called a "parcel"? Perhaps "package" would be better. (It's "Paket" in the original German.)
