 Few would insist that the first sentences of (4) and (5) are really synonymous. What is interesting about this example is that even if we conclude that we should opt for a more fine grained conception of meaning, it is not immediately clear how that will account for the contrast between these sentences. The difference is obviously due to the fact that ‘one’ occurs in the first sentence of (4), which is available as a proper antecedent for ‘it’ and that there is nothing in the first sentence of (5) that could play a similar role. Some authors have suggested that the right way to approach this problem is to opt for a dynamic conception of meaning, one that can encode anaphoric possibilities for subsequent sentences (cf. Heim 1982; Groenendijk &amp; Stokhof 1990, 1991; and Chierchia 1995).
