Identifying PASs in Japanese text is a long-standing challenge chiefly due to the abundance of omitted (elliptical) arguments. One promising approach for addressing this problem is to model argument sharing across multiple predicates (Iida et al., 2015; Ouchi et al., 2015;<cite> Ouchi et al., 2017)</cite> . However, the relation must be easy to identify for human readers who know that the person who asks a question is likely to be answered; namely, the nominative argument of ask is likely to be shared with the dative argument of answer.
