question: candidates:career fair:recruiters
choices.label: A B C D
choices.text: plaintiff:judgment:defendant doctor:registration office:patient producer:seller:manager party a:signing ceremony:party b
explanation: the "recruiter" recruits "candidates" at the "career fair", which is an event process. the "defendant" was sued by the "plaintiff" in court, and the "judgment" is not a process of activity, which is inconsistent with the logic of the query. the "patient" is treated by the "doctor" in the consultation room, and the "registration office" is not an activity process, which is inconsistent with the logic of the query. "producer", "seller" and "manager" are all participants in the process of product production and sales, which is inconsistent with the logic of the query. "party a" signs "party b" at the "signing ceremony", and the "signing ceremony" is an activity process. consistent with the logic of the query.
