Inside a classroom in Barnawa, Nigeria, approximately twenty young individuals, predominantly adolescents, are seated at individual dark wooden desks with metal frames, engaged in a written task. The room features light-colored, worn walls with areas of peeling plaster. A bright light source is present on the left side of the room. Each student has at least one white sheet of paper on their desk and is holding a pen or pencil. Most students are looking down at their papers, actively writing, indicating focused concentration. One male in a red tracksuit with white stripes, centrally located, is looking slightly upwards, with his right hand near his mouth. Other students wear a mix of yellow, green, red, and blue casual attire, some appearing to be tracksuits with white stripes. A calculator is visible on a desk in the mid-left. No overt verbal interactions are observed among the individuals.
