What should be considered before increasing the number of lines in cross-hatching?

Correct answer: The required dark value and whether fine details may be obscured

The correct answer is A. Cross-hatching uses sets of crossing lines to build tone or value. Adding more lines, bringing them closer together, or adding another layer usually makes an area appear darker and visually heavier. Before adding lines, the artist should judge the target value and consider whether the marks will cover highlights, small forms, texture, or other fine details. The lines should also remain controlled so the surface does not become confused. A is correct because it addresses both the intended darkness and the risk of losing information. B is wrong because paper price does not determine the needed line density. C is wrong because a frame is chosen after the drawing and does not control its shading. D is wrong because the title has no effect on mark-making. Memory cue: build darkness gradually and protect important light details.
