Problems: Apart from the problems already pointed out by Catherine and Boris, I would like to mention that the solution has also inconvenience that should be included in the description. For example, sometimes to state explicitly the hierarchy is better than provide axioms to implicitly define it (e.g. Naïve developers can include errors in the axioms).
Clear Problem Description: The problem description is ok; however, I would like to comment that the problem example (with the figure) is not clear enough. I mean it is not clear the meaning of the first hierarchy and of the second; I assume 'classify' means to run a reasoner, but I think this should be explained in the pattern.
