answer the attached question below

1. (14 points) Jenga. Abe and Ben are playing Jenga, which is a game in which the players take turn moving blocks from the bottom to the top of a stack of blocks, and, as more blocks are moved, the tower of blocks becomes unstable. The details of the game are, as usual, common knowledge. There are three possible outcomes: . Outcome A: Abe wins, because Ben places a block which knocks it over. . Outcome B: Ben wins, because Abe places a block which knocks it over. . Outcome C: Nobody wins, because somebody bumps the table which causes them all to fall. First it is Abe's turn, and Abe must choose to Move a block or Shake the table. Shaking the table causes outcome C immediately and the game ends. Moving a block causes it to be Ben's turn, and he has the same choice. After 7 blocks are moved, the eighth block moved will cause the tower to fall, making the person who moves the eighth block to lose. Abe's preferences are: A > C > B Ben's preferences are: B > C > A For each outcome, A, B, and C. explain whether or not that outcome can be part of a rollback equilibrium and why
