/A -> S (If Joffrey does not kill Arya, he must kill Sansa)
But that's wrong because doing so doesn't let you chain the conditionals correctly.
How does that differ from the correct diagram?:
A -> /S (If Joffrey kills Arya, he must not kill Sansa)
The wording in the sentence says "He cannot kill..." so I instantly diagrammed it with a negation and chose Arya randomly: /A , "he cannot kill Arya" and so on.
