Step-by-step explanation:
The details in Stave 2 and 3 contribute to the development of the theme in A Christmas Carol by revealing Scrooge's character transformation. In Stave 2, Scrooge is visited by the Ghost of Christmas Past, who takes him back in time to show him his past experiences and the choices he made that led him to become the person he is. Through these details, we see Scrooge's cold-heartedness and selfishness. In Stave 3, Scrooge is visited by the Ghost of Christmas Present, who shows him the joy and love that can be found in the present moment. These details highlight the importance of kindness, compassion, and generosity, and demonstrate Scrooge's change of heart as he begins to understand the true meaning of Christmas.
