The last question for today
A multiple-choice question about three suspects A, B, C offers the following options as answers. You do not know what the question is, but you know that there is exactly one correct answer. Is it possible to determine the correct answer from the given? Justify your answers.
a).Only A is guilty.
b).B is innocent.
c).Only C is innocent.
d).A and B are guilty.
e).A and C are guilty.
I think it is not possible to determine the correct answer. because answer b) and answer e) are both possible.
春花秋月何时了,往事知多少。 小楼昨夜又东风, 故国不堪回首月明中。 雕栏玉砌应犹在,只是朱颜改。 问君能有几多愁, 恰似一江春水向东流。
