教我这道题,解释你怎么做出来In the finals of a special tug-of-war competition are three sets of well-trained and superbly conditioned athletes. They were matched in various competitions by a computer in order to create the best contests. For the first round, four clowns completed as a team utilizing their well-developed arm muscles. They had proven themselves to be of equal strength to each other. On the other side of the rope were five neighborhood grandmas, a tugging team that had practiced together for many, many years and were also equal in strength to each other. The computer proved to be very accurate in this first round, because the result was a tie. In the second round, one team was Evan, the specially trained tugging dog. Evan was pitted against a team made up of two grandmas and one clown. Again the tugging contest was a tie. The final tug-of-war match is between these two teams: Evan and three grandmas on one side and the four clowns on the other side. Who will win this match?

进入特别拔河比赛决赛的是训练有素和身体健壮的三组运动员.为了使比赛更加精彩,这些运动员都是通过各种比赛由计算机经过精确计算确定的匹配组合.比赛的第一轮,比赛的一方是四名小丑,他们仅用强壮的臂力参加比赛.在此之前已经证明,他们每个人的力量都是一样的.比赛的另一方是五位邻居大妈,这也是一支经过许多年磨练的拔河队,而且,她们每个人的力量也是一样的.第一轮的比赛验证了计算机的准确性,因为比赛结果为平局；比赛的第二轮,一方是埃文这支训练有素的拔河队.他们的对手由两位大妈和一名小丑组成.这一轮的比赛结果又是平局.拔河决赛的最后一轮在这样两个队之间进行：由埃文拔河队加三位大妈组成一方,由四名小丑组成另一方.这一轮比赛谁会取胜呢?最后一轮：一方 = 埃文拔河队加3位大妈 = 5 位大妈 + 1名小丑 = 5名小丑 > 4名小丑 = 另一方答案：由埃文拔河队加三位大妈组成一方将获得比赛的胜利.
