後來我又問了幾個 puzzle，前麵兩個puzzles Bard都回答無誤,

這兩個puzzles are:

Tommy's mother has four sons. The first son is named East, the second son is named South, the third is named West, what is the name of the fourth one?

 

Once upon a time, there were a couple, husband and wife, at age of 36 and 33 respectively, who have lived happily together for 7 years. After 7 years, the wife began to complain that the husband did not listen to her any more. The husband claimed that he always listened to her. The wife then asked him to take a test and the husband agreed to take the test. The wife then began to speak to her husband: Suppose you are driving a bus as the bus driver. At the first station, there were 5 passengers. Going to next station, 1 passenger dropped off, 3 passengers got on; next station, no body off, 10 got on; next station, 5 off, 3 on; next station, 4 off, 9 on; next station, everybody off. Now, can you tell me how old is the bus driver? Well, can the husband know how old is the bus driver?

 

但是第三個puzzle它沒能正確回答:

 

In a jail, there are 1000 prisoners who will be judged tomorrow for death or life. The judging is very interesting: all the prisoners will be randomly put on a hat, either red or green. All the prisoners will be brought into a big hall where they can see the colors of other prisoners' hats except for his own. Also, all the prisoners have no communication with each other. The hall is very quiet. The judge will randomly call a prisoner before him and ask the prisoner for the color of the hat on this prisoner's head. If the prisoner answers the correct color, this prisoner is released; however, a wrong answer means death to this prisoner. Again, there is no communication among the prisoners tomorrow, absolutely no communication except: every prisoner can hear the answer when a prisoner answers the judge.

 

The night before the judging day, the judge gives all the prisoners an offer: he let all the prisoners to stay together to come up with a saving plot so that the prisoners can save as many people as possible. Can you come up with a plot to save as many prisoners as possible? How many you can guarantee to save?

第三個puzzle，它的第一次回答還接近正確答案，至少它意識到偶數奇數，但我告訴它沒能做對後，它就越做越差了。

 

Way to go, dear Bard.
