A, B, C, D and E are either women's volleyball players or women's basketball players. Although they know their profession, others don't know it. At a party, they asked everyone to reason according to the following statements. A said to B: 'you are a member of the women's volleyball team. 'B said to C:' you and Ding are both women's volleyball players. 'C said to Ding:' you and B are both women's basketball players. Ding said to Wu: 'you and B are both women's volleyball players. 'e said to a:' you and C are not women's volleyball players. "If it is stipulated to tell the truth to people in the same team (that is, women's volleyball team to women's volleyball team and women's basketball team to women's basketball team) and lie to people from different teams, who are the women's volleyball players?
Women's volleyball players and women's Basketball Players
A. A, B, C
B. A, C, D
C. A, B and e
D. A, B, D
E. B, C, e
answer:
First of all, we analyze the sentence a to B said. A said: 'you are a member of the women's volleyball team. It can be inferred from this sentence that a must be a member of the women's volleyball team. Why? Because a and B are women's volleyball players or women's basketball players, it can be deduced from four combinations: A and B women's basketball team (1) women's basketball team (2) women's volleyball team (3) women's volleyball team (4) the title stipulates that the truth should be told to the same team members and lies to other team members. Then, (1) and (2) are impossible. So, a is a member of the women's volleyball team. Analyze what e said to a. Wu said: 'you and C are not women's volleyball players. It is known that a is a member of the women's volleyball team, so what Wu said is a lie. Therefore, e is a member of the women's basketball team. Analyze what Ding said to Wu. Ding said: 'you and B are both women's volleyball players. It is known that Wu is a member of the women's basketball team, while Ding is lying. So Ding is a member of the women's volleyball team. From what C said to Ding, we can find out that C told lies. C and Ding Yi, so C is a woman basketball player. Finally, from what B said to C, it is found that B is lying. B is the same as C. B is a member of the women's volleyball team. A, B and D are women's volleyball players.
