What becomes clear in a picture through overlapping shapes?

Which shape is in front and which is behind

Overlapping happens when one shape covers part of another shape. The covered portion is not fully visible, so the viewer interprets the covering shape as being in front and the partly hidden shape as being behind. This is a simple way to suggest depth and spatial order on a flat surface. Overlap is not a measurement of paper thickness, nor does it identify materials, smells, or tools. It is a visual relationship between shapes based on what hides what.

Option A is correct because the overlap shows which shape is closer and which is farther away in the picture. If shape X covers part of shape Y, X is generally read as being in front of Y. The other options concern physical paper properties, smell, or the name of a brush, none of which can be determined from overlapping outlines. Thus, overlap mainly clarifies front-and-back position.
