Among lower-paid workers, union members are less likely than nonunion members to be enrolled in lower-end insurance plans imposing stricter limits on medical services and requiring doctors to see more patients, and spend less time with each.
(A) imposing stricter limits on medical services and requiring doctors to see more patients, and spend
(B) imposing stricter limits on medical services, requiring doctors to see more patients, and spending
(C) that impose stricter limits on medical services, require doctors to see more patients, and spend
(D) that impose stricter limits on medical services and require doctors to see more patients, spending
(E) that impose stricter limits on medical services, requiring doctors to see more patients and spending
原文意思：说工会成员比非工会成员更容易进入一个保险计划，这个计划对于医疗服务限制更多，并且要求医生看更多的病人并且减少每个病人的就诊时间。
题目分析：原文体现了两个并列关系，一个就是plans要impose一个事并且要require一个事，而require下面还有一对并列，就是require医生来看更多的病人并且减少每个病人的就诊时间，A连用两个and，到底是四重并列，还是两个两重并列，容易引起歧义，干掉。
B后面那个and spending和前面的see无法形成并列，干掉。
C这个两个两重并列体现的还可以，留着。
D后面用，spending，虽然可以把这两个两重并列区分砍，但是和前面那个see无法形成对应（有些人给出的答案是D，我搞不懂）
E又用and spending和前面那个see无法对应，杀！
