Final answer:
Lila's reaction to Marcello Solara's proposal is negative or indifferent, based on the provided text.
Step-by-step explanation:
In the story, Lila's actual reaction to Marcello Solara's proposal is not explicitly mentioned, so we cannot determine her exact response. However, based on the provided text, we can infer that Lila's reaction is negative or indifferent towards Marcello's proposal.
When Lila leans close to Lassiter and asks if he would do anything for her, it suggests that she may have some feelings for him. This could indicate that she is not interested in Marcello's proposal.
Additionally, the description of Lassiter's face changing and Lila feeling him immovable as a wall of stone implies that Lila may not be easily swayed or convinced by Marcello's offer.
