Verbal

Employee productivity can, on average, be directly linked to the nutritional value of an employee’s diet and the degree to which that employee is adequately hydrated. In a recent study of underperforming employees, the least productive among them were those who had the least nutritional diets. In a subsequent component of that same study, the underperforming employees were placed on nutrient-rich diets, and productivity steadily increased over the six month span of the study. Consequently, to boost productivity, employers should seek to promote nutrient-rich diets across its workforce to the maximum extent feasible.

Which one of the following, if true, most strengthens the argument?

A. Several study participants were already documented as those who underperformed their peers in terms of workplace productivity.

B. The least productive employees from the same company in the study who were not placed on nutrient-rich diets did not demonstrate a steady improvement in productivity.

C. Sponsoring nutrient-rich meal programs at work can be less expensive than many other means to boost workforce productivity.

D. Some employees who demonstrated poor job performance had consumed nutrient-poor meals within the prior week.

E. Several study participants were already on record as consuming nutrient-poor diets before entering the study.
