Flawed Parallel ReasoningDiff: Hard
Logic Breakdown
Passage Summary: The speaker argues that because there is no punishment for littering, the city is off the hook for providing trash bins.
Conclusion: The city has no obligation to provide trash cans.
Reasoning: The city only has an obligation to provide trash cans if the law punishes littering, and currently, the law does not punish littering.
Analysis: This stimulus exhibits the formal logic flaw known as 'Denying the Antecedent.' The structure is: If P (punishment), then Q (obligation); Not P; therefore, Not Q. This is a mistake because it assumes that a littering law is the *only* possible reason the city might be obligated to provide bins. To find the parallel, look for an answer choice that follows this exact 'If A then B; Not A; therefore Not B' pattern, ignoring other potential causes for the result.

Unlock Full Passage21.Which one of the following exhibits a flawed pattern of reasoning most similar to that in the argument above?
Correct Answer
D
D mirrors the form. If the flight had been late, then the speaker would have missed the meeting (Late -> Miss). The flight is on time (not Late), so the speaker concludes they will make it (not Miss). That’s denying the antecedent: being on time doesn’t guarantee attendance; there could be other reasons to miss.
