Final answer:
The provided texts do not explicitly detail what Hama had locked up in her attic, and further context from the story or text that mentions Hama is necessary to answer the student's question accurately.
Step-by-step explanation:
Based on the given excerpts, it appears that the student's question may be a reference to an object or person Hama had locked up in her attic, but none of the provided texts explicitly answer this question. The references to rooms and areas such as attics do not specify what Hama, if referring to a character from a story, had locked away. It might be possible that the question refers to a storyline or character outside of the provided excerpts. Further context from the specific story or text in which Hama is a character would be necessary to provide an accurate and detailed answer.
