Solving the dilemma between uniqueness and mention some*

Most wh-questions admit only exhaustive answers. For example, to properly answer (1), the addressee needs to specify all the attendants to the party, as in (1a). If the addressee can only provide a non-exhaustive answer, then he needs to indicate the incompleteness of his answer. For instance, he can mark his answer with a prosodic rise-fall-rise contour (in the following indicated by ‘.../’), as in (1b). We call (1a) a complete answer while (1b) a partial answer. If a partial answer is not properly marked, such as taking a falling tone as in (1c) (in the following indicated by ‘\’), it gives rise to an undesired exhaustivity inference.
