Mizuno, Teruyuki and Michael Yoshitaka Erlewine, 2017. “Constraints on contrast sluicing.”
Japanese/Korean Linguistics 24, pages 201–214.

In this paper we investigate contrast sluicing in Japanese and English. The evidence presented here sheds light on the LF syntax of multiple wh-questions and the derivation of sluicing in Japanese, as well as the syntax/semantics of contrast. This paper is organized into two parts. Section 1 discusses the syntax of sluicing in Japanese with novel data on contrast sluicing with multiple whquestions. Section 2 investigates a semantic constraint on contrast reflected in
both sluicing and unreduced contrasting questions.
