question: car:transportation
choices.label: A B C D
choices.text: greenhouse:vegetables hourglass:time fitness:athletics chinese medicine:diet therapy
explanation: "cars" can be used for "transportation". "greenhouse" can be "vegetables". the function of "greenhouse" is not "vegetable", which is inconsistent with the logic of the query. "hourglass" can be used to "time". there is no obvious logical relationship between "fitness" and "athletic", which is inconsistent with the logic of the question. the function of "chinese medicine" may be "diet therapy", but the function of "chinese medicine" is not "diet therapy", which is inconsistent with the logic of the question.
