求解释~~~

答案是B

xiruihuang

namely 不是连词不能连接一个句子，所以应该namely that +句子，排除AE

C选项，it指代不明，而且句中没有任何名词能代替it。
D选项 considerable 一般是修饰抽象名词的，比如 time， money， attention, 所以 a considerable variation i不恰当;some fraternal twins resembling each other greatly and others looking quite dissimilar 在原文意思就是指fact，用 with结构+it is a fact that 是不准确的而且繁琐的：感觉with。。。。伴随的一个fact, 但其实with后面的话就是fact。
不知道你明白我的解释没？
