Final answer:
Clarissa's change of mind about accompanying Mary is related to a profound internal development, paralleled by the experiences of other characters who undergo personal awakenings and reassess their decisions.
Step-by-step explanation:
The changes in Clarissa's decision to not go with Mary to feed the snowbirds can be linked to the complex realizations characters have in these literary passages. Clarissa's internal conflict or revelation, much like that of other characters such as Bernice, Louisa, Claire, and Helmer is rooted in a deep personal awakening or change in perspective. These characters grapple with issues like self-identity, societal expectations, and personal values, which ultimately lead to significant shifts in their decisions and actions.
