In a large, open room, Kofi stands with his back against a wall, looking straight ahead. There is a hat rack beside him to his right, which holds a wide-brimmed hat that obstructs his peripheral vision on that side. Directly across the room, on the opposite wall, there is a colorful painting. To Kofi's left, there is a large potted plant, and slightly further to his left stands Sameera, who is looking directly at Kofi. Behind Sameera, a small window provides a view of the exterior. Meanwhile, behind Kofi, there is a mirror mounted on the wall he is leaning against, at his eye level, which allows him to see behind himself when he looks into it. Consider these questions: What can Kofi see directly in his line of sight without turning his head? Can Kofi see Sameera, and if so, how? Can Sameera see the painting on the opposite wall? Provide a brief response.
Kofi, positioned with his back against the wall and looking straight ahead, can see whatever is directly in front of him in the room. Since there are no obstructions mentioned in his direct line of sight, his primary focus would be the colorful painting on the opposite wall. The hat rack to his right with the wide-brimmed hat would likely block his peripheral view of that section of the room, meaning he cannot see the part of the room to his immediate right without turning his head.

Kofi can see Sameera, but not directly. The mirror mounted behind him allows him to see behind himself. As Sameera is positioned slightly to his left and is looking at him, she would be reflected in the mirror, making her visible to Kofi through the indirect line of sight provided by the mirror.

Sameera, standing to Kofi's left and facing him, would not be able to see the painting directly because Kofi is between her and the painting. However, she may be able to see a reflection of the painting if she is at the correct angle to glimpse the artwork in the mirror over Kofi's shoulder. Nonetheless, this is not guaranteed because the angle may not precisely align with her line of vision, especially if she is focusing on Kofi and not trying to look at the reflection in the mirror behind him.
