explanation: "photography" and "painting" are two forms of artistic expression, both of which utilize the human visual sensory system. "copying" and "scanning" are both ways of working with documents, but neither are artistic expressions. "calligraphy" and "embroidery" are both traditional chinese arts, both of which are forms of artistic expression, and both utilize the human visual sensory system. "carving" and "grinding" are two processing processes, and "grinding" can be carried out on the basis of "carving", but neither is an artistic expression. "singing" and "playing" are two artistic expressions, but both are related to the auditory sensory system.
