Which term describes a volume production process involving machines controlled by humans?

• A. Mechanized production
• B. One-off production
• C. Natural fibres
• D. Oxidization resistance

Answer: (A)

Mechanized production describes a volume production process where machines do the work under human control. The machines handle the repetitive, precise tasks, while a person sets up the equipment, starts cycles, feeds materials, and monitors quality, making adjustments as needed. This combination boosts output and consistency compared with purely manual methods, without the fully autonomous control seen in automated systems. The other options don’t fit because one-off production is for a single item, natural fibres refer to a material, and oxidization resistance is a property—none describe how products are manufactured in large quantities with human-guided machinery.
