This Problem of the Week is another logic problem. It is a variation of the famous puzzle off of which the True and False POW was based. The answer to this question will not be revealed until Sunday at 12:00 AM EST can be found here.

Problem of the Week

You are a contestant on a game show. You have the opportunity to ask three questions to three androids: A, B, and C. Each question that you ask may only be directed to one android. One of these androids always responds truthfully, one of them always responds falsely, and the third always responds randomly; thus their names are True, False and Random. Although they understand every human language and can respond without hesitation, they will only respond in their own language. The following are two words in their language: da and su. One of these words means yes while the other means no.  In order to make it easier for you, they will only answer yes or no questions. Since you don’t know which word is which or even which android is which, what three questions could you ask in order to determine the identity of the three androids?
