In a room with walls that are completely transparent to people with x-ray vision, Kofi and Jing are standing on opposite ends. Kofi, who has x-ray vision, places a bookshelf full of books against the center of one of the walls. Jing, who does not have x-ray vision, is on the opposite side of the room. What does Kofi see and what does Jing see from where they are standing? Provide a very brief response.
Kofi, with x-ray vision, can see through the walls and therefore can see Jing standing at the opposite end of the room despite the bookshelf in the middle. The bookshelf and the books do not obstruct his view because his x-ray vision allows him to see through those as well. To Kofi, the room appears as if there are no barriers between him and Jing.

Jing, who does not have x-ray vision, can see the room clearly apart from what is hidden behind the bookshelf. Since the bookshelf is full of books, Jing cannot see Kofi or the wall directly behind the bookshelf. Jing's view is limited to the parts of the room not blocked by the bookshelf and the books in her direct line of sight.
