If balanced use of both hands is possible in a task, why is it ergonomically good?

Answer and explanation

Correct answer: Continuous strain and fatigue on one hand are reduced

Balanced use of both hands distributes the workload instead of placing continuous demand on one hand, wrist, and arm. This can reduce local fatigue and the risk of repetitive strain or injury, making the task ergonomically better. Requiring more force or increasing awkward posture are ergonomic risks, not benefits. Exam tip: In ergonomics, options that improve load distribution, force, and posture are usually correct.
