question: medication:surgery:treat
choices.label: A B C D
choices.text: train:road:transport cash:credit card:finance material:spirit:civilization email:sms:communication
explanation: both "drug" and "surgery" are means of "treatment", and "treat" is a verb. "train" is a kind of "transportation" tool. "road" is a kind of road, and there is no obvious logical relationship between the two. "cash" and "credit card" are both instruments of "finance", but "finance" is a noun. both "material" and "spirit" are aspects of "civilization", but "civilization" is a noun. "email" and "sms" are both ways of "communication", and "communicate" can be a verb.
