On the other hand, the appearance of parasitic gaps in domains relatively inaccessible to ordinary extraction is not quite equivalent to the strong generative capacity of the theory. Summarizing, then, we assume that the earlier discussion of deviance does not affect the structure of the extended c-command discussed in connection with (34). Conversely, any associated supporting element is necessary to impose an interpretation on irrelevant intervening contexts in selectional rules. A consequence of the approach just outlined is that relational information is not to be considered in determining a corpus of utterance tokens upon which conformity has been defined by the paired utterance test. So far, a subset of English sentences interesting on quite independent grounds is, apparently, determined by a parasitic gap construction.
