Directions: Refer to the passage below and answer questions given below it.
The inhabitants of the Island of Middle Andaman Island have very bright and interesting lives. Just as we earthlings have continuity in our routine lives, the inhabitants of the Island of Middle Andaman Island have continuity in both their waking lives, as well as their dreams. As a result, the inhabitants of the Island of Middle Andaman Island have great difficulty in knowing whether they are awake or asleep at a given time. However, the inhabitants can be classified into two broad types—Awakers and Asleepers.
An awaker is characterized by the fact that everything they believe while they are awake is true, and everything they believe while they are asleep is false. An Asleeper on the other hand, has the characteristic that everything he believes while asleep is true, and everything he believes while awake is false.
The Island has a King, an advisor and a Doctor. At one point, the Doctor believed that his bosses were of different types. Twelve hours later, he changed his state (from sleeping to waking or from waking to sleeping), and he then believed that the King was an Awaker and the Advisor was an Asleeper.
Q. At one time, an inhabitant believed that he was both asleep and awake, what was he really?
