 For a detailed critique of the recent literature on knowledge-wh, see Chapter 2 of Stanley 2011. Parent (2014) provides a survey of the recent literature about knowledge-wh organized around three issues: the reducibility of knowledge-wh to knowledge-that, the relativity of knowledge-wh to a contrast proposition, and the issue of whether the context-sensitivity of knowing-wh is to be understood as a semantic or a pragmatic phenomenon. Uegaki (2019) provides an overview of recent work on the semantics of responsive predicates generally and is organized around four approaches: the reduction of questions to propositions, the reduction of propositions to questions, the uniformity approach (on which declarative and interrogative complements of a responsive predicate are of the same semantic type), and the ambiguity approach (which postulates distinct proposition-taking and question-taking readings of a given responsive predicate).
