choices.text: saw:flower plane:fish paddle:foot gas mask:pig nose
explanation: "Spacesuits" are invented partly based on the imitation of "shrimp shell", because a "shrimp shell" is flexible but hard. "saws" are invented based on the imitation of leafs with a spiny texture, not "flowers". "Planes" are invented based on the imitation of birds, not "fishes". "paddles" are invented based on the imitation of fins, not "feet". "gas masks" are invented based on the imitation of "pig noses", because pigs stick their noses into the soil to filter poisonous gas.
