	abstract = {<p>In this paper, I present two adaptive logics for Wisniewki{\textquoteright}s notion of question evocation. The first is based on an erotetic extension of Classical Logic, the second on an erotetic extension of S5. For both logics, I present the semantics and the dynamic proof theory. The latter is especially important in view of the fact that question evocation is a non-monotonic relation for which there is no positive test. Thanks to its dynamical character, the proof theory moreover solves the logical omniscience problem to which Wisniewski{\textquoteright}s static definition of question evocation leads.</p>},
