choices.text: bulb:power on:lighting paper:print:read satellite:launch:communication cloth:cut:keep out the cold
explanation: only through "disc" "burning", can the "disc" "stores". and "storage" is the main function of a "disc". the "bulb" can only perform the function of "lighting" when it is "powered on", and "lighting" is the main function of the "bulb". "paper" can be "read" only after it becomes printed matter through "printing", and the main function of "paper" is not "reading". "satellites" are divided into natural satellites and artificial satellites. only artificial satellites need to be "launched", and "communication" is only one of the many functions of artificial satellites. "cloth" is "cut" to make clothes, and the main function of "cloth" is not to "keep out the cold".
