["I'm stupid because all smart people are nearsighted and my vision is good.", 'All sheep have four legs, but this animal has eight legs, so it is not a sheep.', 'Horses are four-hoofed herbivores, cattle are four-hoofed herbivores, so cattle are horses.', 'All geniuses are highly myopic, I must be highly myopic, because I am a genius.']
