At the bottom of the picture, we see a black table on which adapters, extension box, scale, projector, laptop, pen and a speaker box are placed. Beside that, we see a man is standing and he is trying to explain something. Behind him, we see a white color board with some text written on it. On the left side, we see the projector screen which is displaying some text. In the right bottom, we see a black color object. In the background, we see a wall on which posters or charts are pasted.
