Final answer:
The provided texts do not include any information about what Ruthie's mom does with Ruthie's old rag doll. The story from Helen Keller references her own experience with a doll, which is not directly related to Ruthie's situation.
Step-by-step explanation:
The narrative in question does not provide a specific action that Ruthie's mom takes with Ruthie's old rag doll. Instead, it seems to tell the story of the author, Helen Keller, and her experience with her own doll under the tutelage of Miss Sullivan.
In the provided text, Keller talks about feeling the broken pieces of her new doll after throwing it on the floor, and how Miss Sullivan swept away the fragments, which may imply some sort of cleaning up or discarding, but this is about Keller's experience, not Ruthie's. None of the provided snippets from other narratives or choices (a-d) directly answer the question regarding Ruthie's mom and the rag doll.
Based on the provided information, there is no clear answer regarding the actions of Ruthie's mom with Ruthie's old rag doll, as this scenario doesn't appear to be covered in the provided texts.
