question: enterprise:research and develop:production:sales
choices.label: A B C D
choices.text: doctor:diagnosis:treatment:comfort farmer:sow:weed:harvest student:take class:exam:graduate writer:concept:write:submit
explanation: "enterprise" must first "research and develop", then "produce", and finally "sell". "enterprise" is the main body, "research and develop" belongs to the exploratory stage, "production" belongs to the implementation stage, and "selling" belongs to the ultimate goal. "doctor" first "diagnoses" and then "treats". there is no obvious time sequence between "treatment" and "comfort", and "comfort" is not the ultimate goal. "farmers" first "sow" and then "weed" and finally "harvest", "sowing" is the implementation stage, not the exploration stage. "students" first "take classes" and then "exams" and finally "graduate", "taking class" is the implementation stage, not the exploration stage. "writer" first "concept" then "write" and finally "submit", "writer" belongs to the main body, "conception" belongs to the exploration stage, "writing" belongs to the implementation stage, and "submission" belongs to the final purpose.
