|
once upon a time there was a man with a bag of grain, a wild goose, a stoat, and a goat.
|
|
|
|
 |
|
|
|
he came to a moat with a boat. the boat can only hold the man and one other. the goat can swim across by itself.
|
|
|
|
 |
|
|
|
how does he get everyone across?
|
|
|
|
 | |  |
| if he takes the stoat, the goose will eat the grain. | |
