Prep13-SC一题

Prep13 

  A Food and Drug Administration rule implemented in December 2000 mandates that any new drug that they intend to be used both by adults and children must undergo pediatric study and that its manufacturers list children's doses on the label.

A.     drug that they intend to be used both by adults and children must 

B.     drug whose intended use is for adults and children as well 

C.     drug intended for use by both adults and children 

D.     drug, if they intend that it be used by adults and also children, must 

E.     drug, if intended for use both by adults and children, must 

为划线部分的“and that its manufacturers list children's doses on the label.”让我疑惑不已，一直搞不清楚是和那里平行？对选项有没有影响。此题应该怎么做呢？麻烦大家帮个忙看看

正确答案是C

应该是mandate that .......and that .......两个that从句平行

其实我觉得可以用mandate来排除，有must的统统pass

B结构奇怪，as well 用法不对，排。。。。

应该是这样吧？！
