Adaptation notes. Reading rewritten in our voice. Polymorphism is illustrated with several Iowa State campus-member classes that each answer a describe() call differently. Hidden tests check polymorphic dispatch over a list of mixed objects (inheritance itself is the next lesson, so the exercise focuses on the same-method-different-class idea).
