Why are symptoms compared with work process in ergonomics?

Answer and explanation

Correct answer: Because it helps identify causes and risky steps

Direct answer: A, it helps identify causes and risky steps. A work process is made of separate actions, such as reaching, lifting, pressing, turning or repeating a movement. If discomfort becomes stronger during one particular action, that timing gives a useful clue about the exposure causing it. The observer can then examine posture, force, duration, repetition and equipment at that step and suggest a safer change. A is correct because comparing symptoms with the sequence of work supports cause-finding rather than guesswork. B is incomplete and misleading: symptoms are experienced by a person, but their pattern may still be related to work conditions. C is the opposite of ergonomic analysis. D is false because the purpose is to improve work, not automatically stop it. Memory cue: find when the pain rises, then inspect what the worker is doing at that moment.
