Passage Summary: Marion has two ways to get to work on time: leave early or take the train. She can't leave early because she has to go to the bank, and she hates the train. Because she dislikes the train, she decides she is definitely going to be late.

Conclusion: Marion will inevitably be late for work.

Reasoning: To be on time, Marion must either leave 45 minutes early or take the train; she cannot leave early because of her bank trip, and she refuses to take the train because she hates it.

Analysis: Marion is confusing 'I don't want to' with 'I can't.' While she has a strong distaste for the train, it remains a functional option that would allow her to arrive on time. The argument is flawed because it treats a personal preference as if it were a physical impossibility. Look for an answer choice that highlights this gap—specifically, that the author ignores an available option simply because the subject finds it unpleasant.
