John: It was wrong of you to blame me for that traffic accident. You know full well that the accident was due to my poor vision, and I certainly cannot be held responsible for the fact that my vision has deteriorated. Michiko: But I can hold you responsible for your hazardous driving, because you know how poor your vision is. People are responsible for the consequences of actions that they voluntarily undertake, if they know that those actions risk such consequences. The principle that Michiko invokes, if established, would justify which one of the following judgments? ['Colleen was responsible for missing her flight home from Paris, because she decided to take one more trip to the Eiffel Tower even though she knew she might not have sufficient time to get to the airport if she did so.', 'Colleen was not responsible for losing her job, because, knowing that her position was in danger of being eliminated, she did everything possible to preserve it.', "Colleen was responsible for her cat's being frightened, because, even though it was her brother who allowed the door to slam shut, she knew that cats are often frightened by loud noises.", 'Colleen was responsible for having offended her brother when she reported to him an offensive comment made about his colleague, although she did not know her brother would mistakenly understand the comment to be about himself.']
