01 Why should very dark lines be avoided at the beginning of a drawing?
Answer and explanation
Correct answer: C. They are difficult to correct or erase
Explanation: The governing drawing principle is to begin with a light construction sketch. Gentle pressure makes temporary outlines for shape, proportion, and placement; these can be adjusted or erased without harming the paper. Very dark lines press graphite into the surface and may leave marks, so option C is correct. Dark lines should be added only after the form has been checked, while the other choices describe effects that do not occur.
