How does the authors discussion of the hobbit and the hunger games contribute to the development of the main idea of the text

According to a different source, this question refers to the text "The Hero's Journey" by Jessica McBirney. In this text, the author discusses the most common characteristics of stories that feature heroes. She develops the idea that most of these stories follow the same general pattern. One way in which she demonstrates this is by looking at such a pattern in both The Hobbit and The Hunger Games.
