Which arrangement reduces strain in a long ICT lesson?
A. A screen on the floor so the neck stays bent for the whole lesson.
B. A screen near eye level, a supported back, and short breaks to look away and move.✓ 答案
C. No breaks, because rests are what cause strain.
D. The dimmest possible screen in a dark room, with no other change.
解說
Ergonomics covers posture, screen position and breaks. Working without a pause, or bending the neck for an hour, increases strain.
