choices.label: A B C D
choices.text: food:table work:life knowledge:books product:enterprise
explanation: "tv" can spread "advertisement", and "tv" belongs to a carrier and has the function of spreading. "food" can be placed on the "table", but the "table" has no function of spreading. both "work" and "life" belong to different situations, and "life" cannot spread "work". "books" can spread "knowledge", and "books" belong to a kind of carrier and have the function of dissemination. "enterprise" produces a "product", and "enterprise" cannot spread the "product".
