Which of the following most logically completes the passage?
Garnet and RenCo each provide health care for their employees. Garnet pays for both testing of its employees' cholesterol levels and treatment of high cholesterol. This policy saves Garnet money, since high cholesterol left untreated for many years leads to conditions that require very expensive treatment. However, RenCo does not have the same financial incentive to adopt such a policy, because .

A. early treatment of high cholesterol does not entirely eliminate the possibility of a stroke later in life
B. the mass media regularly feature stories encouraging people to maintain diets that are low in cholesterol
C. RenCo has significantly more employees than Garnet has
D. RenCo's employees are unlikely to have higher cholesterol levels than Garnet's employees
E. the average length of time an employee stays with RenCo is less than it is with Garnet

E). The average length of time an employee stays with RenCo is less than it is with Garnet.

Explanation:

As per the question, option E most reasonably completes the given passage.  It appropriately states the reason for RenCo not having the similar financial incentive like Garnet to adopt such a policy because 'The average length of time an employee stays with RenCo is less than it is with Garnet'. Since Garnet offers timely testing and treatment of its employees' cholesterol levels and problems associated with it that helps them save a huge amount while Renco does not require to adopt such policy due to the reason that the average time of an employee stays with RenCo being lesser in comparison to former and therefore, they don't need to provide them with timely testing or treatment.  Therefore, option E is the correct answer.
