GWD7-Q3:
The state has proposed new rules that would set minimum staffing levels for nurses, rules intended to ensure that at least one nurse is assigned for every four patients put through triage in a hospital emergency room.

A.rules intended to ensure that at least one nurse is assigned for every four patients put through triage in a hospital emergency room
B.rules with the intent of ensuring one nurse at least to be assigned for every four patients to be put through triage in a hospital emergency room
C.rules intending to ensure at least one nurse is assigned for every four patients in a hospital emergency room put through triage
D.with the intent of ensuring that at least one nurse should be assigned for every four patients in a hospital emergency room that are put through triage
E.and this is intended to ensure one nurse at least to be assigned for every four patients put through triage in a hospital emergency room

正确答案是A

但我觉得这里面逗号前后是两个完整句子   应该不符合英文习惯吧
求高人点拨

A选项逗号后面是同位语。intended to ensure是定语后置修饰rules
