Common indicators might include discussions around personal growth, understanding others, appreciation for different viewpoints, or narratives that illustrate positive interactions among diverse groups.
For example, an excerpt might mention how exposure to different cultures fosters empathy or reduces prejudices. If you have a specific passage in mind, please provide it or its context, and I can help you identify the relevant excerpt!
