Reply To: Further Inference

You are correct to infer that R cannot be in the first position 🙂 If there were only three total candidates [P, O, R], and P must come before both O and R, then yes P would have to go first, with O going either second or third and R going either second or third.

However, there are six total candidates, so while P could go first, it doesn’t have to. Since there are two candidates that must come after P, and no candidates must come before P, this means that the earliest P can go is first, and the latest it can go is fourth.

Hope that helps 🙂
