is paper studies a type of question-answer sequences which accomplish what can be considered as a delicate activity due to its projected sequential develop- ment. In contrast with other formats of question-answer sequences with di er- ent functions (i.e. eliciting information, checking the questionee’s knowledge, etc.), here the studied format seems to count on the questionee’s lack of knowl- edge, consequently projecting the questioner’s own answer. is hypothesis is examined through a detailed analysis of video-recorded guided tours in French and Italian. e paper describes the di erent sequence trajectories occurring a er the guide’s question, and the di culties both participants may nd in deal- ing with the procedure.
