Question

_____ gradually change direction, while _____ create a sense of motion.
a. (1) curvilinear lines; (2) diagonal lines c. (1) diagonal lines; (2) freeform shapes
b. (1) texture; (2) horizontal lines d. (1) curvilinear lines; (2) color

please select the best answer from the choices provided

○ a
○ b
○ c
○ d

Explanation:

To solve this, we analyze each option:

• Option a: Curvilinear lines curve, so they gradually change direction. Diagonal lines are slanted and create a sense of motion (as they imply movement or dynamism).
• Option b: Texture is about surface quality, not direction change. Horizontal lines are stable, not for motion. Eliminate.
• Option c: Diagonal lines don't gradually change direction (they have a fixed slant), and freeform shapes are not primarily for "creating motion" in the same way lines are. Eliminate.
• Option d: Color is about hue, not motion. Eliminate.

So option a fits the description.

Answer:

A. (1) curvilinear lines; (2) diagonal lines
