请教run-on sentence 或者是while的用法。。。。

Helmet_007

这道题正确答案是A，我想说A难道不是一个run-on sentence吗？就是一个句子中的两个完整的句子结构用Fanboys以外的连接词连接是不对的。难道是我对while的用法有误解？

The continental United States receives an average of 30 inches of precipitation a year;transpiration from soil and from plants returns approximately 21 of the 30 inches to the atmosphere, while the balance of 9 inches contributes to the flow of streams and rivers.

• A
  
  transpiration from soil and from plants returns approximately 21 of the 30 inches to the atmosphere, while the balance of 9 inches contributes to the flow
  
  
  
• B
  
  even though transpiration from soil and from plants returns approximately 21 of the 30 inches to the atmosphere, the remainder of 9 inches contribute to the flowing
  
  
  
• C
  
  although transpiration from soil and from plants return approximately 21 of the 30 inches to the atmosphere, the balance of 9 inches contribute to the flowing
  
  
  
• D
  
  with transpiration from soil and from plants to return approximately 21 inches to the atmosphere, the rest of the 9 inches contributes to the flow
  
  
  
• E
  
  as transpiration from soil and from plants return approximately 21 of the 30 inches to the atmosphere, the rest of the 9 inches contribute to the flow

while是从句连词 FANBOYS是并列连词 都可以连接两个完整的句子

一,这不是run on  分号后面可以接完整句子
二,while 引导的从句没啥问题. FANBOYS 是并列连词
