question: eyes:lights
choices.label: A B C D
choices.text: aircraft carrier:sail lawn:environmental protection mountain:landscape ear:sound
explanation: in order to see "lights", we need "eyes", and "eyes" are organs. an "aircraft carrier" can "sail", and an "aircraft carrier" is not an organ. the "environmental protection" vision can be achieved through "lawn", but "lawn" is not an organ. the "mountain" is a kind of "landscape", but the "mountain" is not an organ. "ear" can hear a "sound", and the "ear" is an organ.
