The passage provides three examples of classism displayed by characters in S.E. Hinton's novel "The Outsiders". First, the Socs (upper-class gang) go around getting drunk and jumping Greasers (lower-class gang). Second, when a Soc corrects one of the Greaser gang members, he angrily defends his honor due to feeling insulted by someone of a lower class. Third, one of the Greaser characters speaks condescendingly to his mother, believing himself superior to her due to differences in class. These examples show how class divisions cause conflicts and hardships between the gangs in the novel.
