question: smart:stupid
choices.label: A B C D
choices.text: man:woman black:white sunglasses:brightness wealth:poverty
explanation: "smart" and "stupid" describe the high and low iqs of human beings, but in addition to the "smart" and the "stupid", there are people with average iqs. "men" and "women" are contradictory, and there is no other case that falls outside these two. "black" and "white" each are a kind of color, but in addition to "black" and "white", there are also red, blue, etc. "brightness" and "sunglasses" have no obvious logical relationship. the lack of "wealth" is because of "poverty".
