A recording shows a professor in a classroom giving a presentation to an audience of students. The professor is a woman with long hair, seen from the back. She faces a projected screen, presenting a slide titled "The profession that the world still doesn't know." The classroom has tiled ceilings with lights and air conditioning vents, red walls, and a tall white column. Students are seated at desks, facing the presentation. Some have water bottles on their desks. A flat-screen TV on the wall mirrors the projector's content.
