In Passage 1, Lisa's internal motivation is her fear of thunderstorms, which makes her feel terrified and urges her to stay under the blankets. This fear represents a strong emotional barrier that influences her actions and thoughts.
On the other hand, Lisa’s external motivation is her concern for her little brother, who is crying during the storm. This motivation compels her to overcome her own fear and take action to comfort him.
These motivations shape her actions by creating a conflict between her instinct to hide from the storm and her sense of responsibility and love for her brother. Ultimately, her external motivation triumphs, prompting her to gather her courage and rush to his side, demonstrating how the bond of family can inspire individuals to confront their own fears for the sake of others.
