Read this paragraph from the passage "Why We Buy What We Buy." Twitchell began studying products and advertising 15 years ago, when he was teaching about poetry: "I suddenly realized my students had no interest in what I had to say!" But his students could flawlessly recite the contents of a Big Mac: two all-beef patties, special sauce, lettuce, cheese, pickles, and onions on a sesame-seed bun. How does the paragraph help contribute to the overall idea that advertisements play a significant role in American life? It proves young people are best at retaining information that comes from advertisements. It suggests that American culture is shaped more by advertising than by education. It indicates that American educators are finding more satisfying careers in advertising. It demonstrates the power of effective, memorable advertising.
