What problem can a very faint line cause?

Correct answer: The shape may not appear clear

Direct answer: a very faint line can make the shape unclear. Lines often define the outer boundary, important edges, internal divisions, or construction of a drawing. If a line is too light to be seen, the viewer may not recognise where the form begins or ends. Option A is correct because insufficient line visibility reduces clarity and makes the shape difficult to identify. Option B is incorrect because paper normally tears from excessive pressure, rough handling, or weak paper, not because a line is faint. Option C is incorrect because the visibility of a line has no direct connection with the price of colour. Option D is incorrect because line faintness cannot change the physical weight of a frame. A faint line may be useful for a light preliminary sketch, but it should be strengthened when the final outline must be clear. Memory cue: a line should be light when it is only a guide, but clear enough when it must communicate the final form.
