In a library, there are three rooms: Room A, Room B, and Room C. Jake is studying in Room A, Mia is reading in Room B, and Alex is working on a project in Room C. Each person knows that there is a hidden treasure somewhere in the library, but they don't know its exact location. Jake overhears a librarian saying that the treasure is not in Room A. He then leaves the room and tells Mia what he heard. Afterward, Mia hears another librarian say that the treasure is not in Room B either. She decides to keep this information to herself. What does Alex think about the location of the treasure based on his knowledge?

Provide a very brief response.
Based on Alex's knowledge, there is no reason for him to have a specific opinion about the location of the treasure unless he has received information that the other two haven't. From what is provided, Alex does not have any information about the treasure's location that would differentiate between the rooms since there has been no mention of Alex overhearing any hints nor has there been any indication that Mia shared her knowledge with him. Consequently, Alex should still think that the treasure could be in any of the three rooms, including his own Room C, since he has not received any information that would lead him to think otherwise.
