An artist wants a flat-brush stroke that begins broad becomes thin in the middle and broad again at the end. Which pressure sequence is most suitable?

Correct answer: Heavy pressure then light pressure then heavy pressure

The governing concept is pressure-based modulation of brush width. With a flat brush, heavier pressure spreads more bristles against the surface and produces a broader mark; lighter pressure reduces contact and produces a thinner mark. To obtain broad–thin–broad, the artist should use heavy pressure, then light pressure, then heavy pressure. Therefore option A is correct. The reverse sequence gives thin–broad–thin, equal pressure keeps the width similar, and pressure only at the end cannot form the complete pattern.
