} The goat was left behind on the far bank while you dealt with the wolf
} and the cabbages. Unfortunately, you left him with the two natives, one
} who always tells the truth, and the other always lies (and you can't
} tell which is which). If you asked the right question, you'd know not
} to pick door #2, which has the wolf behind it, who will tear you to
} pieces. Meanwhile, the cabbages (35kg) were being used as a
} counterweight to help a queen (91kg) and her son (49kg) and daughter
} (42kg) escape from the tower using two baskets (if the difference in
} weight is more than 7kg the basket will fall too fast). The boat is
} being manned by a ferryman, but you have to find the right coin to pay
} him among twelve counterfeits, using only three weighings of a balance
} scale. (Remember, don't pay him until he gets you to the other side.)
} The natives, the ferryman, the queen, her children and Monty Hall all
} have green marks on their foreheads, which they can't see, but when
} they realise they have the marks, they must leave at noon the next day.
} Once they're all gone (seven days later), that leaves you with the car.
