The textbook authors use the example that Latina/o teens are more likely than Anglo teens to "make fun of people who try to do well in school" to illustrate which concept?

A) defiant disorder
B) oppositional culture
C) involuntary minority
D) model minority

The concept being illustrated is oppositional culture, which refers to a cultural orientation that opposes mainstream values and norms, including academic achievement. This can manifest as a tendency to mock or criticize those who do well in school, as the textbook suggests is more common among Latina/o teens. Defiant disorder is a psychiatric diagnosis referring to a persistent pattern of behavior characterized by negativity, disobedience, and opposition to authority figures. Involuntary minority refers to a group that becomes a minority due to external factors such as social, economic, or political forces rather than personal choice. Model minority refers to a minority group that is said to have achieved higher levels of success than the average population, typically due to cultural values emphasizing achievement and hard work.
