还是搞不明白为什么逗号加reducing不对，逗号加v-ing的结构可以表伴随（这里说不通），也可以表结果，这里 ...

Ron关于 comma+v.ing modifier用法的讲解：

1) when you use a COMMA -ING modifier after a clause**, you should actually satisfy TWO requirements:
-- the modifier should modify the action of the preceding clause, as you have stated;
AND
-- the subject of the preceding clause should also make sense as the agent of the -ING action.

examples:
Joe broke the window, angering his father. --> this sentence makes sense, because it correctly implies that joe "angered his father".
the window was broken by Joe, angering his father. --> this sentence doesn't make sense, because it implies that the window (i.e., not joe himself) angered joe's father.

my brother tricked me, disappointing Dad --> implies that dad is disappointed in my brother for tricking me (and not necessarily disappointed in me for being tricked).
i was tricked by my brother, disappointing Dad --> implies that dad is disappointed in me because i fell for my brother's trick (and not that he's disappointed in my brother for tricking me).

这题区别不在是否有that吧，区别在于逗号+Ving
Ron在论坛上讲过，逗号+Ving修饰的对象是前面一个clause的主语+谓语，V动作发出者一定要和主语有关系。

同意ls  svo,ving不应该做定语除非没有逗号才能做noun modifier  只有ving在句首或主语后的才有可能是noun modifier

因为没有that,reducing的逻辑主语就变成了ancestors了，那意思就变成是ancestors reducing了their number ...

作为伴随的话，要看前面句子的主语， our ancestors reducing.... 讲不通的

在GMAT中 逗号+V-ing的形式是有表伴随的意思，但是首先要考虑的是Ving的逻辑主语是谁，你可以看下Manhatt ...

针对A答案我是这样理解的哈
错误点应该在于reducing那里
reducing可以做伴随也可以做结果状语，那么就来考 ...

我有一个问题， 看OG的解释说破折号后的句子是解释believe后面的东西，所以要平行加that
我的理解是可不可以把破折号后面的句子当做是解释“”Population Bottleneck”的句子，所以就不需要加that，等于是解释一个名词的同位语，谢谢NN们

Some anthropologists believe that the genetic homogeneity evident in the world’s people is the result of a “population bottleneck”-at some time in the past our ancestors suffered an event, greatly reducing their numbers and thus our genetic variation.
A. at some time in the past our ancestors suffered an event, greatly reducing their numbersB. that at some time in the past our ancestors suffered an event that greatly reduced their numbers
C. that some time in the past our ancestors suffered an event so that their numbers were greatly reduced,
D. some time in the past our ancestors suffered an event from which their numbers were greatly reduced
E. some time in the past, that our ancestors suffered an event so as to reduce their numbers greatly,
