Answer:
to stress the danger of Tío Juan's being off on his own
Step-by-step explanation:
This question is about the book "Seedfolks" that covers the story of 13 characters of different origins, lives and personalities with one thing in common, the search for a better life in America. To emphasize the difference between the characters, the author uses several rhetorical resources, including points of view and auternative perspectives and even shared between more than one perspective. An example of the shared perspective can be seen in the question above, where Gonzalo shares the perspective with his mother to emphasize the danger of Tío Juan being alone.
