Final answer:
Without access to the specific text concerning Castor and Sophie's situation, a factual answer cannot be provided. Literature analysis typically requires direct reference to the text.
Step-by-step explanation:
The question seems to be referencing a scene from a piece of literature, but without the context of the specific text to which the student is referring, it is not possible to provide a factual answer. In literature classes, students often analyze characters, plot, and dialogue within texts.
To answer questions like these, one would need to have access to the passage where Castor reacts to an event involving the number 1, Sophie, and a golden egg-laying goose. Since this information is not provided here, it is advisable to read the text carefully to understand the context and character reactions.
