GWD6-Q31:
The fact of some fraternal twins resembling each other greatly and others looking quite dissimilar highlights an interesting and often overlooked feature of fraternal-twin pairs, namely they vary considerably on a spectrum of genetic relatedness.

A. The fact of some fraternal twins resembling each other greatly and others looking quite dissimilar highlights an interesting and often overlooked feature of fraternal-twin pairs, namely they vary considerably
B. That some fraternal twins resemble each other greatly while others look quite dissimilar highlights an interesting and often overlooked feature of fraternal-twin pairs, namely that they vary considerably
C. With some fraternal twins resembling each other greatly and others looking quite dissimilar, it highlights an interesting and often overlooked feature of fraternal-twin pairs, namely considerable variation
D. With some fraternal twins resembling each other greatly and others looking quite dissimilar, it is a fact that highlights an interesting and often overlooked feature of fraternal-twin pairs, namely a considerable variation
E. Because some fraternal twins resemble each other greatly and others look quite dissimilar, this fact highlights an interesting and often overlooked feature of fraternal-twin pairs, namely they vary considerably

看了以前很多解释，但我还是没有明白真确的B中“ namely that they vary considerably"是什么结构？看上去像定从，但非限制性定从是不用that的啊？？？？？

没看前辈们的解释，凭自己的理解试一下吧~
That （some fraternal twins resemble each other greatly while others look quite dissimilar ）highlights an interesting and often overlooked feature of fraternal-twin pairs, namely that （they vary considerably）。
我感觉是同位语从句。两个That都引导同位语从句。 namely，意思是：即。
这两个同位语从句的意思是一样的，后者是前者的另一种说法。
欢迎大家指正啊！

你的解释我也想过，从句意上看像同位语，查遍了所有同位语的结构也没有这种奇怪的结构，好困惑啊，无法理解

njkf1987

不好意思，我表达错了，应该是主语从句。

E只能用namely后面没有that来排除吗?the fact让我觉得别扭，可是也说不出怎么错
