There are several phenomena generally thought to involve long-distance dependencies at LF, such as scope marking, long-distance list answers and correlatives. In this book they are handled by explicating novel types of local relationships that interrogative and relative clauses can enter. A more articulated semantics is shown leading to a simpler syntax.
Among other issues addressed is the switch from uniqueness/maximality effects in single wh constructions to list readings in multiple wh constructions. These effects are captured by adapting the treatment of wh expressions as quantifying over functions to the cases of multiple wh questions and correlatives. List readings due to functional dependencies are systematically distinguished from those that are based on plurality.
