+        \subsection{Problem With Adaptive Hint}
+
+        % Adaptive hints are messages provided to students which depend on
+        % student input.  These hints are produced using a script embedded
+        % within the problem (written in Python).  
+        %
+        % Here is an example.  This example uses LaTeX as a high-level
+        % soure language for the problem.  The problem can also be coded
+        % directly in XML.
+        
+        This problem demonstrates a question with hints, based on using the
+        {\tt hintfn} method.
