This Friday, Aron Hirsch and Bernhard Schwarz will present their joint work on which-questions.
Title: Singular which, mention-some, and variable scope uniqueness.
We present data that we take to support the conclusion that the uniqueness presupposition of singular which-questions is not triggered by an answer operator, as proposed in Dayal (1996), but is instead triggered by which itself. The key observation is that uniqueness may be introduced at a low site, below where the answer operator necessarily takes scope. Our conclusion clears the way for an attractive analysis of mention-some questions, put forward in Fox (2013).
As usual, we will be meeting at 3pm in Room 117. All are welcome to attend!
