一道伴随语态的题

1. Among lower-paid workers, union members are less likely thannonunion members to be enrolled in lower-end insurance plans imposing stricterlimits on medical services and requiring doctors to see more patients, andspend less time with each.

(A) imposing stricter limits on medical services and requiringdoctors to see more patients, and spend
(B) imposing stricter limits on medical services, requiring doctors to see morepatients, and spending

(C) that impose stricter limits on medical services, requiredoctors to see more patients, and spend

(D) that impose stricter limits on medical services and requiredoctors to see more patients, spending

(E) that impose stricter limits on medical services, requiringdoctors to see more patients and spending   

比较D和E，D选项spending动作的发出者是doctors, make sense，而E选项spending动作的发出者是medical services，没道理，因此选D  OA: D

以上是解释 但是楼主觉得D也有问题啊 D拆分开来就是the insurance plans that require doctors to see more patients, spending less time with each. 所以这里spend动作的发出这不是insurance plan？
