Lee, Bok-hee. 1999. Focus, Topic and Activated Propositions in Information Qnestions. Studies in Modern Grammar 17, 141-161. This study discusses the formal and pragmatic principles which govern the placement of sentence accent in English and Korean information question from the perspective of information packaging. I distinguish three kinds of pragmatic presupposition, which correspond to different kinds of assumptions a speaker may have concerning the addressee`s state of mind at the time of an utterance. All three are lexicogrammatically coded in sentence structure. The distinctions among these three presupposition types will play a crucial role in the argument presented in this paper.
