A group of people are exploring a cave a little way up a cliff on the coast. The tide turns and the cave starts to fill with water. The mouth of the cave is very narrow and the first person to clamber out is a very fat woman who manages to get totally stuck. As the cave fills with water, it becomes clear that all of them will drown, except the fat woman, whose head is out of the cave. Curiously, one of the group has some dynamite – enough to remove the woman from the mouth of the cave. There is no other way to get her loose, but this will inevitably kill her. If they don’t use the dynamite, everyone else will drown.
Should they use the dynamite to dislodge the woman?
