The question is: "If I asked the other tribe what color are their feet, what would they answer"? The answer will always contain a single lie. If the answer is red, then the true answer is green. The other tribe has green feet, thus never tells the truth. The tribe answering has red feet and always tells the truth. If the answer is green, then the true answer is red. The other tribe has red feet, thus never tells lies. The tribe answering has green feet and is always lying. Regards, Horace Heffner
