 [R2] and [R4] are correct moves because [R1] and [R3] are. When “the king is seated” is proposed in [O2], it can only be relevant with respect to [R1], which is not the case as disjunctions do not entail their sub-formulas. If the respondent is unaware of the king’s whereabouts, the sentence must be doubted. “You are in Rome” proposed in [O3] is also irrelevant, but can be negated as known to be false in the external world. At that point, “the king is seated” becomes relevant and must be conceded as implied by “the king is seated or you are in Rome” and the negation of “you are in Rome” via disjunctive syllogism ([SCD] 1494: fol. 4rb [1988a: 433–434]).
