To attract the most talented workers, some companies are offering a wider range of benefits, letting employees pick those most important to them.
因为看到A最后是to them杀掉了A，them指代的是employees，不应该是thenselves么？？ 我觉得C正确是因为：offering...letting在这里不一定是因果关系，并列关系用and 也说得通。公司是提供a range of benefits（吸引员工点一：benefits种类多） 和 pick for themselves（吸引员工点二：自由选择）

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.
 
选的是对的，但是想问一下老师。关于逗号ing的用法。一般句子后面拖一个逗号ing不是都是用于要么表示前面整句话发出的，要么是前句主语发出的，这里答案的，spending的主语是谁发出的？是doctor吗，可是这不是不太符合逗号ing的用法嘛
