Young-Sik Choi (Seoul National University). 2002. QP and WH-Scope Interaction (wh- 의문문의 양화사와 의문사의 Scope 상호작용). Language Information. Volume 5. 33-52.
There has been two proposals regarding QP and wh-scope interaction. One is that a single answer as well as a pair list answer is derived from the scope interaction between the QP and the wh-word as proposed by May (1985). The other is that both readings are special cases of a functional answer as claimed in Engdahl (1985) (and also Chierchia 1991). In this paper, I suggest that the single answer is wide scope of the wh-word over the QP and the pair list answer is a special case of the functional answer, taking an eclectic view of the two proposals.
