Chandra, Katlego, and Isra are in a classroom while their friend, Leandro, has just stepped out to answer a phone call. Before Leandro left, he placed his water bottle on a desk near the window. While Leandro is outside, the sun moves and starts to shine directly on the water bottle. Isra notices this and moves Leandro's water bottle to a spot on a shelf that is not in direct sunlight. Just after Isra moves the water bottle, Chandra and Katlego return from the library, neither of them aware of the water bottle's original or new location. When Leandro comes back to the classroom, who will know where Leandro's water bottle is?
Provide a very brief response.
When Leandro returns to the classroom, only Isra will know the location of Leandro's water bottle. This is because Isra was present in the room and directly observed the bottle being affected by the sunlight and then took action by moving it to a new location. Although Chandra and Katlego were not present to see Leandro's original placement or Isra's subsequent action, they have not observed the current location of the bottle on the shelf. Since Leandro was not in the room when this change occurred, he will also be unaware of the new location of his water bottle. Thus, each person's knowledge of the water bottle's location depends on their presence and observation at the time of its movement, making Isra the only one with the current knowledge of its location.
