Final answer:
Daisy agrees to accompany Molly due to her wish for independence and to meet her friend, Mr. Giovanelli, whom she values as an intimate companion, whereas Gracie's reasons are implied to be social loyalty or adherence.
Step-by-step explanation:
The two reasons Daisy and Gracie agree to accompany Molly are related to their personal motivations and social dynamics presented in the excerpts. Daisy appears to be driven by a desire for independence and social interaction, particularly highlighted when she decides to walk with Mr. Giovanelli despite her mother's concern. Moreover, the allure of engaging with an intimate friend in the form of Mr. Giovanelli gives Daisy a strong social incentive to leave her mother's side. On the other hand, Gracie's motivations are not explicitly stated in the provided text, but it can be inferred that she might be following Daisy's lead, showing a form of social adherence or loyalty to her friend.
