Passage Summary: If you cause a problem on purpose, you're in trouble; if it was an accident you couldn't have predicted, you shouldn't be blamed.

Reasoning: The passage establishes rules for blame: knowingly causing misfortune warrants blame, but unwittingly causing it may not, especially if it was unforeseeable.

Analysis: This is a Principle Justify question, so we need to find a specific scenario in the answer choices that perfectly mirrors the logic of the provided rules. The most powerful rule here is the 'never' condition: no blame if the act was both unwitting and unforeseeable. You should look for a scenario where someone causes a negative outcome by accident and had no way of knowing it would happen, concluding that they are not at fault. Avoid choices that try to blame someone for an accident that *was* foreseeable.
