question: sculpture:painting
choices.label: A B C D
choices.text: government:democracy politics:faith mechanics:optics samples:examples
explanation: "sculpture" and "painting" belong to different art forms. "democracy" belongs to "polity", and there is no obvious logical relationship between "polity" and "democracy". "politics" and "belief" are biased. "mechanics" and "optics" belong to different scientific disciplines. "sample" has a similar meaning to "example".
