This paper provides evidence that
-ambiguities derive from two distinct sources, with the precise nature of a particular ambiguity being dependent on the particular type of predicate (Result-State or Degree-Achievement) present in the sentence. Previous research has focused primarily on sentences containing Result-State predicates (e.g.
) rather than Degree Achievements (e.g.
), and has located the source of the ambiguity in the scope that
takes with respect to
in a syntactically decomposed predicate. I argue that entailment facts preclude such an analysis from applying to sentences containing Degree Achievements and
. Instead, I propose that Degree Achievement predicates should be decomposed into comparative structures, and that the ambiguity in such sentences arises from the scope
takes with respect to a comparative Degree Phrase, rather than a
