求NN解答一个关于RON 视频上comma+VING的问题

今天也要加油鸭

这个题RON 的视频里有讲过，RON说不选A的解释是因为outnumber没有因果关系，我觉得这里是次要的结果啊。类似这个句子里bringing的作用？

Five fledgling sea eagles left their nests in western Scotland this summer, bringing to 34 the number of wild birds successfully raised since transplants from Norway began in 1975.

Emily Dickinson’s letters to Susan Huntington Dickinson were written over a period beginning a few years before Susan’s marriage to Emily’s brother and ending shortly before Emily’s death in 1886, outnumbering her letters to anyone else.

• A
  
  Dickinson were written over a period beginning a few years before Susan’s marriage to Emily’s brother and ending shortly before Emily’s death in 1886, outnumbering
  
  
  
• B
  
  Dickinson were written over a period that begins a few years before Susan’s marriage to Emily’s brother and ended shortly before Emily’s death in 1886, outnumber
  
  
  
• C
  
  Dickinson, written over a period beginning a few years before Susan’s marriage to Emily’s brother and that ends shortly before Emily’s death in 1886 and outnumbering
  
  
  
• D
  
  Dickinson, which were written over a period beginning a few years before Susan’s marriage to Emily’s brother, ending shortly before Emily’s death in 1886, and outnumbering
  
  
  
• E
  
  Dickinson, which were written over a period beginning a few years before Susan’s marriage to Emily’s brother and ending shortly before Emily’s death in 1886, outnumber
  
  
  

     另外想问一下，逗号+VING的用法是不是1.判断和前面一句话subject的关系 2.需要与前面一句话形成立刻发生的结果（强调同时性）或者是次级动作？这里的low-priority action和有人说的进一步解释说明是一样的吗？

     快被绕死了...

为什么有因果关系呢？前面一部分只是解释了写信的时间长度，和写的数量无关。

楼主给的例子有关的原因是五个走了以后变成34个，所有有因果关系。

v+ing的用法，首先确定ing的动作和主语是否一致；以及，考虑1/是不是在同一个time frame；2/是不是前面的直接后果

楼主给的例子有关的原因是五 ...

因为时间长所以数量多 我好像自己补了一个gap...
我再想想谢谢哈。
那RON所说的那种low-priority action是什么意思啊，这样感觉用VING的情况都得被归为同时且立刻发生的结果了...
另外有些题他说VING可以用作进一步解释？类似这个：Hydrocarbons, with which fruit flies perfume themselves in species-specific blends, are known to be important in courtship,  apparently assisting flies that taste the hydrocarbons on prospective mates in distinguishing their own species from others.

想了一晚上还是有点绕，求解啊。VING和主句的逻辑关系到底是什么样的，所谓解释说明的那种是什么情况啊？

今天也要加油鸭

我再自己顶顶吧...

天惹... 大家都没有这个疑问吗...
