choices.label: A B C D
choices.text: band:band leader tourist:guide volunteer:summon students:instruction
explanation: the "army" follows "order", and "army" is a collective concept. the "band" obeys the "band leader", and the "band" belongs to the concept of collection. the "tourist" follows the "guide" instead of obeying, and the "tourist" can be an individual or a whole, which does not belong to the concept of collection. "volunteers" respond to "summon" instead of obeying. "volunteers" can be individuals or a whole, and do not belong to the concept of collection. "student" obeys "instruction", "student" can be an individual or a whole, and does not belong to the concept of collection.
