Which field concerns optimizing safety and efficiency by analyzing how people interact with their work environment?

• A. Ergonomics
• B. Chemistry
• C. Physics
• D. Nutrition

Answer: (B)

Ergonomics is the study of designing workspaces, tools, and tasks to fit how people actually move, see, reach, and think. It aims to optimize safety and efficiency by analyzing how workers interact with their environment and their equipment. In practical terms, this means arranging desks, chairs, computer screens, keyboards, lighting, and workflow so that tasks can be performed with less strain, fewer mistakes, and greater comfort. By aligning the work setting with human capabilities, you reduce risk of injury from repetitive motions or awkward postures and you improve speed and accuracy of tasks, which is especially important in settings like healthcare reception where smooth, safe patient flow and accurate information handling matter a lot. Chemistry, physics, and nutrition focus on different domains—molecules and laws of nature, physical properties, and dietary aspects—rather than on optimizing the interaction between people and their work environment.
