question: sparrow:animal:biological chain
choices.label: A B C D
choices.text: soy milk:breakfast:soy products boiling water:paper cup:convenience goods hair clip:jewelry:makeup pen:computer:office product
explanation: "sparrow" is an "animal", and the "animal" is part of a "biological chain". "breakfast" could contain "soy products", and "soy products" could also be "breakfast". "boiling water" can be placed in a "paper cup", and "boiling water" is a "convenience goods". "hair clips" are a kind of "jewelry", and "jewelry" is a kind of "makeup". there is no obvious logical relationship between "pen" and "computer", and "office product" includes "pen" and "computer".
