However, these roles are crucial for interpreting verb-noun and adjective-noun metonymies.
to Vendler (1968), who acknowledges that logical metonymies may trigger more than one interpretation (in other words, that there may be more than one possible event associated with the noun in question), Pustejovsky implicitly assumes that nouns or noun classes have one (perhaps default) telic role without, however, systematically investigating the relative degree of ambiguity of the various cases of logical metonymy (e.g., the out-of-context possible readings for fast scientist suggest that fast scientist exhibits a higher degree of semantic ambiguity than fast plane).
