explanation: both "detective comics" and "comic strips" are "comics", and some "detective comics" are "comic strips", and some "comic strips" are "detective comics". "visible light" is the part of the electromagnetic spectrum that the human eye can perceive. electromagnetic waves with different wavelengths cause the human eye to perceive different colors. "red light" and "purple light" belong to "visible light", but "red light" and "purple light" are side by side. . "collection of cultural relics" and "prehistoric cultural relics" are both "cultural relics", and some "collected cultural relics" are "prehistoric cultural relics", and some "prehistoric cultural relics" are "collected cultural relics". the "troposphere" and the "mesosphere" belong to the same category, the "troposphere" belongs to the "atmosphere", and the "mesosphere" does not belong to the "atmosphere". both "cation" and "anion" are "ion", but "anion" and "cation" belong to the same class.
