01 Which ability improves through regular sketching practice?
Answer and explanation
Correct answer: C. Observation and line control
Explanation: The governing concept is skill development through repeated practice. Regular sketching trains the eye to observe proportion, direction, spacing, and structure, while repeated hand movements improve steadiness, pressure control, and confidence in making lines. Thus option C is correct because observation and line control develop together. Paper cutting, colour mixing, and applying glue may be useful craft skills, but they are not the specific abilities developed by sketching practice.
