In a room with a single window on one wall, Zelda is standing with her back against the opposite wall, facing the window. There is a tall bookshelf right in front of the window, which stretches from the floor to the ceiling. Orion enters the room and stands directly behind the bookshelf, facing Zelda. Can Zelda see Orion? Make your response very short.
Zelda cannot see Orion because the bookshelf is directly in front of the window and stretches from the floor to the ceiling, thereby obstructing any direct line of sight between them. The bookshelf acts as a barrier, preventing Zelda from seeing Orion, who is standing behind it.
