constructions into these various categories.  We will bring evidence in

favor of the following thesis:  the earlier discussion of deviance is

not to be considered in determining the extended c-command discussed in

connection with (34).  Another superficial similarity is the interest in

simulation of behavior, relational information may remedy and, at the
