explanation: "newspapers" and "magazines", both of which are important carriers of mass communication, have the function of reflecting and guiding social public opinion, but in addition to "newspapers" and "magazines", there are other mass communication carriers. "plastic" and "glass" are both raw materials, but in addition to "plastic" and "glass", paper is also a raw material, but not a carrier. "tape" and "compact disc" are the same category, but in addition to "tapes" and "compact discs" there are other carriers for information storage. a "bronze mirror" is used as a daily necessity for lighting, and an "iron pot" is used as a cooking utensil for cooking. there is no obvious logical relationship between the "bronze mirror" and the "iron pot". "network" corresponds to "optical fiber". "network" and "optical fiber" is not the same category, and "optical fiber" is a fiber made of glass or plastic, which can be used as a tool for transmitting "network" information.
