    Which of the following conclusions are valid.
    c1 Joe is a Greek geek
    c2 Joe may or may not be geek.
    C1 appears to follow from p1 and p2.

    An axiom in classical logic.

    If a = b and b = c then a = c.

    A rock weighs 100kg. A log has the same weight as the rock. A boat weighs the same as the log. Therefore the boat weighs 100kg.

    Logically why is this valid? What is the proof of the axiom?
