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 if 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



我個人不理解(D)為什麼錯? 還有(E)對什麼對?  



謝謝各位的回答

题目中说到了这个高胆固醇left untreated for many years 才会导致很昂贵的治疗，如果雇员可以在公司待很长的时间， 公司在早期发现了这个病， 就可以节省后期治疗的昂贵费用。因为治疗的费用比检查的高很多

相反的， 如果一个人在公司里呆不了多长时间就会离开， 到离开的时候可能都不需要治疗， 那么这个检查的费用就是白花了， 没有节省费用的功能。
