Flawed Parallel ReasoningDiff: Medium
Logic Breakdown
Passage Summary: To get a specific job license, you must meet two requirements; since Marie meets both, the speaker assumes she is guaranteed to get the license.
Conclusion: Marie will definitely be licensed as an emergency medical technician.
Reasoning: Licensing requires both a high school diploma and CPR competence, and Marie possesses both of these qualifications.
Analysis: This argument commits a classic 'sufficient vs. necessary' error by treating requirements as guarantees. Just because you have the prerequisites for a license doesn't mean there aren't other factors—like an application fee or a background check—that could still get in the way. When looking for a parallel flaw, seek out a choice that says 'To do X, you need A and B; this person has A and B, so they will definitely do X.' It's like saying that because you have a ticket and a tuxedo, you are guaranteed to win an Oscar.

Unlock Full Passage8.Which one of the following contains flawed reasoning that most closely parallels the flawed reasoning in the argument above?
Correct Answer
B
B matches the flaw. It states effectiveness as a teacher requires fluency in at least two languages (E → 2+ languages), then concludes that having 2+ languages makes one effective (2+ languages → E). That’s the same necessary/sufficient confusion as in the stimulus.
