5-Handed Monsters (Simons & Hayes, 1976) Read this problem and underline the parts of the sentences you consider most important. 1. Three 5-handed monsters were holding three crystal globes. 2. Because of the quantum-mechanical peculiarities of their neighborhood, both monsters and globes come in exactly three sizes: small, medium, and large. 3. The medium-sized monster was holding the small globe; the small monster was holding the large globe; and the large monster was holding the medium-sized globe. 4. Because this situation offended their keenly developed sense of symmetry, they proceeded to transfer globes from one monster to another so that each monster would have a globe proportionate to his own size.
