The theme that is revealed through paragraph 53 is this: Gossip can falsely characterize people as good or evil.
What is the theme?
The theme that is evident in the story is that gossip can falsely characterize people. We learn of a newspaper that spread false tales about Native Indians. This resulted in the negative views that people had of Claude and Adele when they finally arrived to study in the city.
So, the lesson from this is that gossip is harmful and can falsely characterize people in ways that are not right. Thus, option D is a striking theme that we see in Cheboygan Day.
