Final answer:
The provided snippets from various texts do not contain information about a character named Erica or the reason behind the naming of her doll. Without additional context, a specific answer to the question cannot be provided.
Step-by-step explanation:
The question does not clearly specify which 'Erica' is being referred to, as it seems to be pulling from different pieces of unrelated texts. However, these texts don't feature a character named Erica; they include references to different characters interacting with dolls. For instance, there's a mention of a blind girl receiving a doll, the word "d-o-l-l" being spelled out, a scene of buying dolls as gifts, and another of a broken doll after a moment of realization. Characters in these excerpts experience varied emotions and social contexts that may influence why they name their dolls the way they do or the personal significance the name carries. The concept of a doll within these different narratives ranges from a plaything for a child to a representation of self or luxury.
However, in none of these snippets is there a character named Erica, nor is there clear context to ascertain the reason behind a doll's name specifically called by Erica. Thus, we cannot provide a specific answer to a question about why 'Erica' names her doll a certain way without additional context or clarification about the literary work or text in question.
