question: congressman:meeting:proposal
choices.label: A B C D
choices.text: racer:race track:racing singer:concert:props employee:negotiation:victory athlete:sports meeting:record
explanation: "congressman" puts forward "proposals" at the "meetings", and the three belong to the corresponding relationship between the person, the place and the main task object. "racer" "racing" on a "race track", and the three belong to the corresponding relationship between the person, the place and the main task object. "singer" sings in "concert", "props" has no obvious logical relationship with the first two words. "employees" can "negotiate", and "victory" is the result of "negotiation". the "athlete" competes in a "sports meeting", and the "record" is the result of the performance in the competition, not the main task of the "athlete" in the sports meeting.
