Question

in a time - motion study of a large e - commerce fulfillment center outside columbus, ohio, workers spend eight - hour shifts scanning barcodes and sliding identical boxes down a conveyor belt, allowed to change stations only during two timed breaks. the report concludes that the chief strain lies in the lack of variation—the ____ of the shift, which steadily erodes attention and morale. which choice completes the text with the most logical and precise word or phrase? a passion b difficulty c improvisation d monotony

Explanation:

The text states the chief strain is from "lack of variation" in the shift. "Monotony" means lack of variety, matching the context. "Passion" (emotional enthusiasm) and "difficulty" (hardship) don't relate to lack of variation. "Improvisation" (spontaneous creation) is irrelevant here. So "monotony" is the logical choice.

Answer:

D. monotony
