Final answer:
The excerpts given do not include characters named Jonah and Chip, or Gary and Hodge, and therefore do not provide information about any attempts to warn other kids. They discuss different characters and a separate plot event.
Step-by-step explanation:
The student's question pertains to whether Jonah and Chip were successful in their attempts to warn the other kids about Gary and Hodge in a story. However, based on the provided excerpts, it does not mention characters named Jonah and Chip, nor does it discuss any attempts to warn others about individuals named Gary and Hodge. It appears that the provided text relates to a scene from a different story involving characters named Peter, Wendy, and their parents, which discusses a return from a trip rather than an attempt at warning others.
