Final answer:
The inquiry about who Bailey called 'snooty' cannot be answered without further context or a specific passage where Bailey uses the term 'snooty.'
Step-by-step explanation:
The student is asking about a character named Bailey who referred to someone as 'snooty.' From the provided passages, none clearly indicate that Bailey called someone 'snooty.' However, Mrs. Costello, a character from one of the passages, does express disapproval by calling someone 'hopelessly vulgar,' which can be synonymous with being disdainful or snobbish, depending on the context.
Unfortunately, without further context or a specific reference that includes the character Bailey, a direct answer to the student's question cannot be provided. If Bailey is a character in one of the excerpts, it would be necessary to have the exact passage where Bailey uses the term 'snooty.' Therefore, one cannot confidently say who Bailey called 'snooty' based on the information provided.
