Final answer:
The excerpts provided do not contain information about what Lexie says Eli will do if food runs out, thus we cannot provide a precise response to the student's question without additional context.
Step-by-step explanation:
The student's question focuses on what Lexie predicts Eli will do if food runs out. Unfortunately, the provided excerpts do not explicitly state Lexie's response concerning Eli's actions in the event of food scarcity. Given the dialogue snippets from various narratives, it's clear they discuss themes related to food shortage, sharing meals, and obtaining resources. However, they don't directly answer what Lexie says Eli will do. To assist the student with their schoolwork question, they may need to refer to a specific text where Lexie's character is present and provides a clearer insight into Eli's potential actions when faced with a lack of food. Without the specific context or text referencing Lexie and Eli, it's not possible to provide an accurate answer to the student's question.
