The visual effect of unit marching is described as the unit moving as a single form. Which option best captures this idea?

• A. The synchronized movement of the unit as a single form
• B. Many individuals moving independently
• C. One body moving
• D. A scattered set of motions

Answer: (C)

The idea being tested is unity of appearance when a unit marches—making the group read as one continuous moving form.

The best choice communicates that the entire unit is perceived as a single moving entity. Saying “one body moving” directly captures that perceptual result: the collective effort looks like a single shape in motion, with steps, posture, and spacing aligning to form that continuous silhouette. This is the visual effect marching aims for.

Describing it as synchronized movement emphasizes coordination, which is related but not as direct a statement about the eye’s overall impression of the unit as a single form. The other options describe independence or disorder, which break the sense of unity the question targets.
