It's not my quiz and I'm grossly unqualified to grade the results. But I doubt language shmanguage wins a free lunch.
One of the principles of free association is that there are no wrong answers. But schmanguage is the wrong answer. In the question, I was speculating that the words in the quiz were derived from an exercise where DFW had asked a separate group to spit out the first word they thought of when he said 'language'. The individual's jumping off point will say something about the speaker, all the words in combination say something about the subject.
Re: the class quiz. What's the first word that pops into your head when I say 'language'?
