What is a likely cause if a poster colour layer cracks after drying?

Answer and explanation

Correct answer: The paint layer being too thick

The governing concept is controlled paint thickness. A very thick poster-colour layer contains more moisture and binder, so it can shrink unevenly as it dries and form cracks. Therefore, option A is correct. White paper, a small brush, or a round palette does not normally cause drying cracks. Applying several thin, even layers and allowing each layer to dry reduces this problem.
