question: pepper:numb
choices.label: A B C D
choices.text: moon:round cement:hard drink:cold flame:hot
explanation: "pepper" must be "numb", and "numb" is an attribute of "pepper". the "moon" is not necessarily "round". "round is not an attribute of the "moon". cement is a powdery material that is mixed with water to form a slurry, which will harden after setting, so "hard" is not an inevitable attribute of "cement". "drink" can be divided into "cold" and hot drinks, and "drinks" are not necessarily all "cold". "flame" must be "hot", and "hot" is the inevitable attribute of "flame".
