small lecture hall, sparsely populated with students seated at wooden desks arranged in rows. A young man stands at the front of the room facing the students. He is writing on a whiteboard mounted on the yellow wall. The students are facing him, mostly from the back view. The room is brightly lit and the desks appear well-used with visible wear. The students are wearing a variety of clothes, and their posture suggests that they are paying attention to the lecturer. The atmosphere is typical of a classroom setting, conducive to learning. A utility box is mounted above the whiteboard.
