Final answer:
The question about Morgana Rothschild staring at Bernard with astonishment cannot be directly answered from the provided text, as it does not contain these characters' names. Instead, the provided text includes other characters displaying surprise and social dynamics through various interactions.
Step-by-step explanation:
The reference to Morgana Rothschild staring "with astonishment" at Bernard is not available in the provided textual references. Instead, it seems the student may have confused the characters or mixed up the names from the provided text, which focuses on other characters such as Bernice, Marjorie, Warren, and others. In the snippets provided, we observe different reactions and interactions among characters, which display surprise, judgment, and social dynamics, but none involving Morgana Rothschild and Bernard.
One of the examples from the provided texts concerns Bernice as she shocks her aunt by revealing her bobbed hair, which was a daring fashion statement at the time and could lead to social astonishment. Similarly, character reactions such as Warren's surprised recognition of Bernice's attractiveness and liveliness at the dance also portray the surprise elements within the social context. This theme of wonder and recognition is consistent throughout the text snippets provided.
