Final answer:
Novinha calls for a Speaker in a moment of distress but is upset when he arrives because she regrets the potential public exposure of her family's secrets and her own past.
Step-by-step explanation:
The question refers to events in the science fiction novel Speaker for the Dead by Orson Scott Card, which is the sequel to Ender's Game. In the story, the character Novinha sends for a Speaker to speak the death of a deceased character. However, she becomes upset upon the Speaker's arrival because her call was an impulsive act driven by anger and grief, and she fears the exposure of her family's secrets and her own personal history. The Speaker's role is to uncover and publicly speak about the true nature and motivations of the deceased, which Novinha fears could lead to further pain and disgrace.
