Which task is most comprehensive for assessing advanced watercolour skill?

Correct answer: Create a small scene using flat and graded washes, glazing, wet-on-wet, dry brush, and controlled edges

The governing concept is authentic, integrated skill assessment: advanced ability is shown by controlling several watercolour variables in one purposeful image. Option B requires the learner to manage pigment-to-water ratios in flat and graded washes, transparency in glazing, flow in wet-on-wet work, texture in dry brush, and precision in edges. Writing colour names or drawing one line measures only a narrow fragment, while soaking paper is merely preparation. Therefore, option B provides the most comprehensive assessment.
