This paper focuses on the semantics of interrogative sentences and has three main parts

This paper presents a substantially revised version of the theory developed in my thesis, Ginzburg 1992a, and in Ginzburg 1992b. All acknowledgements from those works carry over to the present one. In particular, I would like to thank my adviser Stanley Peters for many useful suggestions and encouragement. I would particularly like to thank Robin Cooper: many of the ideas in this current paper arose as a result of joint work, reported in Cooper and Ginzburg 1993, and currently emerging as Cooper and Ginzburg (in progress). I would also like to thank Enric Vallduv'i for extensive comments on an earlier draft and much moral and schm/boozal support, David Milward for many useful suggestions, comments on a draft and occasional skepticism, Elisabet Engdahl for stimulating discussion, the members of the MaC group in Edinburgh and audiences at the 1993 LSA summer institute and the LSA/ASL conference on Logic and Linguistics both at Columbus, Ohio.
