Founded in 1983, the magazine increased its circulation more than double since then, and its advertising.

• A
  
  increased its circulation more than double since then,
  
  
  
• B
  
  has since increased its circulation more than double,
  
  
  
• C
  
  has since more than doubled its circulation
  
  
  
• D
  
  since then more than doubled its circulation
  
  
  
• E
  
  more than doubled its circulation since then
  
  
  

• gmat难题300好难啊~~~这道题答案是C，为什么呢？
• • 怎么判断是more than doubled还是increased more than double啊？
  • 为什么要用现在完成时，因为有since吗？

我觉得这题重点应该在后半句“，and its advertising”上。

这个and就代表前面肯定有一个短语和它并列，但是A B E选项的结尾都是since then、more than double之类的短语，如果后面紧跟一个and its advertising就会很奇怪。 只有C、D选项里“...its circulation，and its advertising.” 的表达是合理的。

用完成时的话确实是看since，然后理解句意应该是说从过去直到现在增加了两倍多，所以是现在完成时，而不能只用一个过去时。

但是A,B后都有逗号和and its advertising隔开了，就算没有和its circulation连着是不是也是对的啊？

用more than doubled就能表达增加两倍的意思了吧
