Picky predicates: why believe doesn't like interrogative complements, and other puzzles

It is a long-standing puzzle why predicates like believe embed declarative but not interrogative complements (e.g., Bill believes that/*whether Mary left) and why predicates like wonder embed interrogative but not declarative complements (e.g., Bill wonders whether/*that Mary left). This paper shows how the selectional restrictions of a range of predicates (neg-raising predicates like believe, truth-evaluating predicates like be true, inquisitive predicates like wonder, and predicates of dependency like depend on) can be derived from semantic assumptions that can be independently motivated.
