 The general conclusion that has been drawn from this problem, as discussed in detail by Ciardelli and Roelofsen (2011), is that question meanings cannot be suitably modeled in terms of indifference relations, even if these indifference relations are allowed to be non-transitive. This insight has led to the development of an alternative logical notion of question meanings, which forms the cornerstone of the framework of inquisitive semantics, to be discussed below.
