ABSTRACT
Parallels Between Wh-Phrases and Indefinites 59
there are data that point to a more intricate picture; I discuss these complications in the next section.
My derivation of the restrictive term of quantified sentences by presupposition accommodation from the nuclear scope was predicated on the observation that the matrix predicates of the sentences in (25) are factive while those of the sentences in (42) and (44) are nonfactive: given the well-known claim that factive predicates presuppose their complement while nonfactive predicates do not, the hypothesis of presupposition accommodation accounts for the difference in interpretation between the two groups of sentences. In view of such desirable consequences of this factivity-based explanation, it is unexpected to encounter sentences such as the following:
