The important thing is not to stop questioning. (Albert Einstein.)

  

1.- A shepherd needs to take a wolf, a goat and a lettuce to the opposite bank of the river. He has a boat where he just fits along with one of the other things. If the wolf is left alone with the goat it will eat it; if the goat is left alone with the lettuce it will eat it. How should he do it?
