Acceptability: "Which could be a complete assignment?" Apply each rule to eliminate choices. Fast — do these first.
Must Be True: "Which MUST be true?" Test each choice against your deductions. If your setup forces it, it must be true.
Could Be True: "Which COULD be true?" Four answers violate rules, one doesn't. Find the one that works.
Must Be False: "Which CANNOT be true?" Same as Must Be True but inverted. If it violates a rule or deduction, it must be false.
New Condition: "If X is in position 3, which must be true?" Add the new condition to your diagram. Make new deductions. Answer the question. Don't change your master diagram.
Strategy: Do Acceptability first (fastest). New Condition questions last (they take longest).
