Marion knows that the bridge on her usual route is closed and that, unless she takes the train instead of driving, she can get to work on time only by leaving at least 45 minutes early. She must go to her neighborhood bank before leaving for work, however, and the bank will not be open in time for her to do so if she leaves 45 minutes early. Ttherefore, since she hates taking the train, Marion cannot avoid being late for work. The reasoning in the argument is flawed because the argument ['mistakes a situation that almost certainly affects many people for one that affects a particular person alone', 'overlooks the possibility that someone might occasionally adopt a given course of action without having a good reason for doing so', 'ignores the fact that people often know that something is the case without considering all the consequences that follow from its being the case', 'treats evidence that someone will adopt a particular course of action as though that evidence excluded the possibility of an alternative course of action']
