explanation: "intelligence" and "emotion" are two human abilities, and "intellect" is rational and "emotion" is perceptual. "sadness" is an "emotion", and "sadness" is a collective term for a class of emotions. "enthusiasm" does not include "hot spots". "science" and "art" are two ways for humans to understand the world, and "science" is rational, while "art" is perceptual. "sculpture" is a kind of "art", and "sculpture" is a general term for a type of art. "yunxia" refers to the morning glow, and "white clouds" are both natural phenomena. "land" and "river" side by side, "yellow river" is "river", but "yellow river" is a specific river, not a class of rivers.
