After analyzing the previous rounds, I notice the opponent has used a pattern of playing rock in even-numbered rounds (2, 4, 6) and paper or scissors in odd-numbered rounds (1, 3, 5). Since this is round 7 (odd), there's a higher chance they'll play paper. Additionally, they've only used scissors once so far (in round 1), making paper a statistically likely choice to balance their selections. With the score at 1-3, I need to be strategic to catch up, and scissors gives me good odds against their predicted paper move.
