Looking at the pattern, my opponent has chosen paper in rounds 2, 5, and 7, showing a tendency to play paper in odd-numbered rounds. Since round 7 was paper, there's a good chance they'll break this pattern to avoid being predictable, but paper remains a strong possibility given they've won with it twice recently against my rock. I've also used rock too frequently (last 3 rounds), making me predictable. Choosing scissors gives me the best chance to counter their potential paper play while breaking my own predictable pattern.
