    We need a rule that helps us derive "should not be held responsible for X". This rule doesn't contain any wording like that. This rule would only allow us to derive a conclusion like "should not protest X".

  2. Correct96% picked this

    Of a player’s actions, only those that are voluntary should be used as justification for disqualifying that

    Why this is right

    We might sidestep this answer on a first pass because it doesn't contain an exact match for our conclusion's wording "should not be held responsible for X". But it does allow us to say, "should not be used as justification for disqualifying from pro chess", so it's still pretty relevant to Marianne's situation. It says, If an action is → should not be used as reason not voluntary for disqualifying from pro chess Marianne's humming is involuntary, so according to this rule, her humming should not be used as a justification for disqualifying her from professional chess. Her current situation is that chess officials have told her that any further humming on her part will disqualify her from professional chess. She is arguing that she shouldn't be 'held responsible' for the humming, and in this context being held responsible means suffering consequences from the chess officials. So this answer supports Marianne's claim that the humming shouldn't be used against her.

    We need a rule that helps us derive "should not be held responsible for X". This rule would only allow us to derive a conclusion like "X should not be considered voluntary". Had there been a principle that was saying "if unaware of X, then X should be considered voluntary", that could have still worked, because the author does have an Intermediate Conclusion ("the humming was involuntary") that we could support.
