p*********g 发帖数: 9527 | 1 A classroom window was broken today. You know that two students were
responsible. There were 4 students inside the classroom, Allen, Beatrice,
Camille and Donald. You know that two of them are the ones who broke the
window, and you also know that all four of them saw who did it. After asking
each of them in turn who broke the window, you receive the following
replies:
Allen: Camille and myself did it.
Beatrice: Allen and Donald did it.
Camille: Beatrice and myself did it.
Donald: Allen and Beatrice did it.
Given that one of them told the complete truth, two of them told half-truths
(i.e. they only named one guilty student correctly) and one of them told a
complete lie, and assuming that it is one of the guilty students who told
the complete lie, which of the students was the one who told the complete
lie? | G*****h 发帖数: 320 | | c*********r 发帖数: 2733 | | c*********r 发帖数: 2733 | 4 所有提到自己的都不可能是犯人。按照这个思路再推一下结果就出来了 | p*********g 发帖数: 9527 | 5 The question is

应该说提到自己的不会是完全撒谎的那个。
