Passage Summary: Since this publisher's nonfiction never makes money, and they made money on everything they put out last year, they couldn't have put out any nonfiction.

Conclusion: Carriage Books did not release any nonfiction titles during the previous year.

Reasoning: Nonfiction books from this publisher never turn a profit, but every single book they published last year was profitable.

Analysis: This is a logically valid argument using the contrapositive structure: If A (nonfiction), then B (no profit). Since we have Not B (profit), we must have Not A (not nonfiction). To find a parallel, look for a set of premises where a general rule is established, a specific set of circumstances contradicts the outcome of that rule, and the conclusion denies the trigger of that rule. The logic is airtight, so the correct answer must also be a valid deduction rather than a fallacy.
