shift-work equations has done two things:

1. reduced: sickness, sleeping on the job and fatigue
2. raised production efficiencies.

Since the shift-work equations reduced 3 things we need 'and' before fatigue. Eliminate A,B&D

Now reduced and raised should be parallel. Since the 'raising' in E is not parallel with 'raised' eliminate E and the answer is C.
