What helps make a line look strong?

Correct answer: Greater thickness and darker pressure

Direct answer: A, greater thickness and darker pressure. A line looks strong when it has clear visual weight. Pressing more firmly and making the stroke thicker usually produces a darker, bolder mark that attracts attention and feels powerful or definite. A is correct because it names the two main qualities described here. B usually produces a delicate, quiet line with less visual weight, so it does not normally look strong. C is incorrect because breaks and fading reduce continuity and force, making the line seem weak or uncertain. D may change the contrast between the line and the paper, but the paper’s light colour is not the quality that makes the line itself strong. In practice, an artist can also vary the tool and repetition, but the basic principle is thickness plus pressure. Memory cue: more pressure, more darkness, and more width usually mean greater visual weight.
