求问prep的一道题

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
  
  
  
  

OA是C 但为什么 后面可以跟undergo 而不是undergoes啊

但是undergo的主语不是any new drug嘛

粗体里面的谓语动词需要用原型，和主语没有关系

mandate 这个词含有命令、强制的语气，因此后面要接动词原形。
undergoes 就得换成undergo
其次must也有必 ...

同意！

mandate 这个词含有命令、强制的语气，因此后面要接动词原形。
undergoes 就得换成undergo
其次must也有必须的意思，和mandate 重复，必须去掉。
both and 平行
所以选C
