The scene contains a still life with a fruit bowl. Other surfaces act as the floor and walls for the scene. The primary light source is a spotlight. The spotlight casts light through a vertical opening in the wall. Some areas in the scene are directly lit and other areas are not.
Shading materials have already been assigned to the bowl, fruit, and other surfaces. The apple and orange models are from the previous lessons. If you want to see what other shaders and textures are in the scene, you can view them by opening the Hypershade editor.
When you render this scene using Global Illumination, the effect you want to achieve is to have the upper and lower regions of the scene receive indirect light: you want to be able to view more detail in the shadow areas as a result of the Global Illumination.
