Final answer:
Meredith's reaction to lice is not explicitly stated, but similar situations in F. Scott Fitzgerald's works suggest immediate and possibly bold action would be taken.
Step-by-step explanation:
In the provided excerpts, Meredith's reaction to finding out she had lice is not explicitly detailed. However, we can infer from the context of F. Scott Fitzgerald's works that handling such a situation would likely involve immediate action to remove the lice and possibly a sense of embarrassment or urgency due to the stigma surrounding lice infestations. In a similar circumstance, Bernice faces a challenge of her own by cutting off her cousin Marjorie's braids as an act of defiance and self-assertion, indicating that in these types of situations, characters in Fitzgerald's stories often take bold steps, whether in health or social matters.
