question: biting:mosquito coils:floral water
choices.label: A B C D
choices.text: attack:radar:torpedo beautification:greening:decoration getting wet in the rain:umbrella:raincoat accident:traffic light:traffic police
explanation: both "mosquito coils" and " floral water" are tools to prevent mosquitoes from "biting". a "torpedo" is a tool for launching an "attack", a "torpedo" is not a tool for preventing an "attack". "greening" and "decoration" play the role of "beautification", and "greening" and "decoration" do not prevent "beautification". "umbrella" and "raincoat" are both tools to prevent "getting wet in the rain". the role of "traffic lights" and "traffic police" is to reduce "accidents", and "traffic police" is a profession, not a tool.
