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 Gar

答案E，我觉得没法解释啊，R的员工肯是跳槽过来，也有cholesterol，这怎么解释不用政策？

R does not care if its current employees will need expensive treatment for high cholestrol in the FUTURE since by that time, these employees are not R's employee and its concern any more.

E怎么能说明问题？我题大约看明白了，你的解释没有说服力，能不能请您在完善下，期待你的解答，跪谢

To use layman's language, let's say R's employees only stay for 2 years, while G's employees stay for 10 years. But the treatment of high cholesterol won't start until the fifth year. R does not need to worry about its CURRENT employees' health in this respect, because by the fifth year, all these employees (and potential bills to cure their diseases) are not R's liabilities.  These employees packed and left three years ago.
