Read the paragraph and answer the question.
An artist who is experienced in oil painting on canvas knows the importance of choosing the appropriate type of canvas for each painting technique. A very smooth canvas is not usually appropriate for thick application of paint, because the paint tends to slide around too much. On the other hand, a very rough canvas is inappropriate for thin painting, because the thin layer of paint will practically disappear in the roughness of the surface.
