I see your point and agree with it.  However, we were presented with a  
question that needed to be answered without arbitration involving  
computer scientists.  The questionable wording indicated to me that  
the author simply meant: the car of ... is ___.  Learning Scheme is  
complicated by these issues of wording; I suppose it is an argument  
for rigorous representation.
