What term describes the vertical stacking of structure rows?

• A. Bays
• B. Levels
• C. Modules
• D. Tiers

Answer: (D)

The term describes a vertical sequence of rows arranged one above another: tiers. It conveys multiple levels stacked in the vertical direction, like levels on a platform or shelves, which fits the idea of vertical stacking of structure rows. Bays refer to horizontal spacing between frames, levels usually mean floors or stories, and modules are individual repeatable units, which don’t inherently capture the idea of vertical stacking. So when rows are positioned at different elevations, calling them tiers best communicates that vertical stacking concept.
