choices.text: temperament:fragility cry:shout tip:prom distillation:purity
explanation: sounds of different "volume" are played through the "sound". "fragility" is a kind of "temperament". "crying" and "shouting" are  the different behaviors. there is no obvious logical relationship between "tip" and "prom". liquids of different "purity" can be "distilled".
