Correct answer: (A) Work distribution between the hands is not balanced.; (B) The hands do not follow opposite motions.
Explanation
The left hand is idle or holds the bolt during many right-hand operations. The right hand fetches, picks, transfers, assembles and releases items. Thus the load is unbalanced and the motions are not coordinated as opposite simultaneous movements. Since the operator is left-handed, the dominant hand is not the one doing most tasks. **A,B**.
