选项A the fact of不好,the fact of fraternal twins强调twins, 应该用the fact that来强调整个fact

选项B That引导的从句作为主语,谓语动词highlights,正好强调了整个事实(some fraternal twins resemble each other greatly while others look quite dissimilar ).

选项C,D第二个分句开头的it没有指代,(it不能指代前面的句子)

选项E错误的引入因果关系,改变了原句的意思.

请教LZ,

原句中,"namely they vary considerably "是否creats a run-on sentence?

choice B 中 "namely that they vary considerably" 是that 引导的主语从句的并列或同位(?)结构吗? 多谢.

我觉得namely后面只能接名词,表示举例子的意思

namely that... 类似the feature that...用同位语的意味在里面

如有不对,欢迎大家提出不同意见

namely  【adverb】
used to introduce more exact and detailed information about sth that you have just mentioned:
e.g. We need to concentrate on our target audience, namely women aged between 20 and 30.

所以这个句子的原貌是
That some fraternal twins resemble each other greatly while others look quite dissimilar, namely that they vary considerably，(到此处为主语) highlights(谓语) an interesting and often overlooked feature of fraternal-twin pairs。
命题者依据避免主语过长的原则，把namely后面的半截移到了句子最后.
