One more YES or NO
Three persons james, micheal, jijo are my friends. One of my friend always tell the truth and others are tell alternatively truth. It means if they first tell truth then next time they tell lie. Suppose if they first tell lie then next time they tell truth. But you don't know first time they tell truth or lie.
You can allowed to ask three questions that must be answered YES or NO. Using the answers you need to find who tell always truth.
What are the questions?
