    Drop the coconuts from the palm tree and empty the milk in to the plastic cups.
    Duct tape the coconuts together to make a floating disk.
    Professor and Mechanic hold on to edges of plastic disk.
    Inflate beach ball for Lucy to hold on to.
    William puts on inflatable flamingo toy.
    Tie every one together with string.
    Drink coconut milk for energy and courage.
    William takes paddle and starts paddling in direction on mainland.
    Paddle can be passed around so each can take a break as needed.
    Everyone is tied together, so nobody gets left behind.
    Everyone is floating, so nobody actually needs to swim.
    Everyone will arrive at mainland, together and safe, so no one needs to call for help.

    Lucy must ask one of the conductors...
    "Which train would the other guard tell me I should take?"
    Lucy should then take the other train.


    If the conductor she asks is the one who lies, then he will lead her astray by telling her (falsely) that the other conductor – the truthful conductor – will advise her to take the second train. This makes the first train the one that Lucy needs to get.


    If the conductor she asks is the one who tells the truth, then he will tell her honestly that the other conductor – the lying conductor –will advise her to take the second train. This makes the first train the one that Lucy needs to get.


    Conversely...

    This can be interpreted more simply as a yes/no question, by asking either conductor, “Would the other conductor tell me that this is the train that I need to take ?”
    The truthful conductor would say No if it was the right train, because the other conductor would lie about it, but the Lying conductor would also say No, because the other conductor would truthfully say that it was the right train.
    If it wasn't the right train, then the truthful conductor would answer Yes, because the other would lie and say that it was, where the lying conductor would say Yes, because the other would truthfully tell her it was the other train.



    Server, Loch Ness, unless Cylinder Head (Express) server is running.

    The only thing I can think of, so far, is a three by three square, with two ducks in each corner.
    Four across top and bottom, four down either side, and from the two pairs, a single diagonal of four, making five groups of four.
    It seems a bit of a cheat, but I've got nothing else.
