The answer would be anecdote. Allusion is a reference to another work. a rhetorical question is a question that requires and does not want and answer. an anecdote is a brief story designed to illustrate something. logic is how some one using reason to come to a sound/valid conclusion. An anecdote is not so strict on content. The content of the anecdote is logic reasoning. It could just as easily have been an anecdote for something like irony.
