 51(b) is exemplified by the situations in which it is true. This makes the situations exemplifying negative sentences a rather disparate batch that do not resemble each other in any intuitive sense. If we want to quantify over situations exemplifying the propositions expressed by negative sentences, as we do in (52) below (repeated from above), contextual restrictions for the topic situation must play a major role, including those contributed by the topic-focus articulation and presuppositions (Kratzer 1989, 2012; von Fintel 1994, 2004a). Exemplification is not expected to make any contribution here, which is the result we want to derive.
