Step-by-step explanation:
Christine suspects Leroy has been talking to Rhoda about sensitive topics. The passage provided does not directly reference the characters involved, as it appears to be from a different context, most likely from a play or a novel where characters like Christine and Rhoda interact. In the context of the student's question, it is clear that Christine is concerned about the source of Rhoda's information on particular sensitive matters and considers Leroy a potential informant. This suggests a storyline involving communication and secrets among characters, a common element in literature and drama.
