A.
Team 1: (1) + (-3) = 1 - 3 = -2
Team 2: (4) + (-5) = 4 - 5 = -1
B.
Team 2 is winning after two games, as -1 is greater than -2.
C.
Team 1: (-3) + (1) + (-4) + 4 = -2
Team 2: (4) + (-5) + (9) + (-9) = -1
No, the results would be the exact same. This is because both Team 1 and Team 2 got scores in game 3 and game 4 that add up to a total of 0, so the only scores that affected the final scores are that from Game 1 and Game 2.
Hope this helped!
