Final answer:
The irony in the last sentence of paragraph 9 is that the story-teller admits to not believing his own tale, after delivering a story about the acceptance of life's situations with humor. The story-teller's previous arguments and reveals the absurdity of his claims
Step-by-step explanation:
The last sentence of paragraph 9 in the story "gambling in school" is ironic because the story-teller admits to not fully believing the story he just finished telling. Throughout the story, the narrator has engaged the audience with a tale meant to illustrate that every situation has its advantages.
The ending statement, where the story-teller expresses his own skepticism about the story's truth, is ironic because it undercuts the message presented in the tale. This ending suggests that not all is as it seems, even within the story itself, and serves as a final twist for the reader. The irony lies in the fact that the story-teller delivers a syllogism on taking life with humor and then confesses to doubting parts of his own humorous tale.
