A row of dots can give the impression of what?

Correct answer: Line

Direct answer: A, a line. When dots are placed close together in a row, the eye tends to connect them and perceive a path from one dot to the next. This is called an implied or dotted line: the line is not drawn continuously, but its direction is still understood. A is correct because the repeated dots create the visual impression of continuity and direction. B is incorrect because a frame is a border around an artwork, and a row of dots does not automatically surround or contain the picture. C is incorrect because colour temperature describes warm and cool colour qualities, not the visual connection between dots. D is incorrect because paper weight is a physical property of paper and cannot be shown simply by arranging dots. The dots should be sufficiently organised for the eye to read them as a path; widely scattered dots may not create the same effect. Memory cue: close repeated dots can make an implied line.
