A. a controversial B. a statistical C. an analytical D. an explicit E. an unimpeachable
这道题同样,a bit of arcane knowledge noted only by bibliographers.是前面的___ fact的同义重复,所以空格应填入文献学家关注的事实,已知的五个选项里显然只有B选项的statistical(统计的)是文献学家的份内工作。
(4) 凭借具有指示作用的形容词或代词来寻找重复
Longdale and Stern discovered that mitochondria and chloroplasts ___ a long, identifiable sequence of DNA; such a coincidence could be ___ only by the transfer of DNA between the two systems.
A. manufacture.. accomplished B. reveal.. repeated C. exhibit.. determinedD. share.. explained E. maintain.. contradicted
下半句的such a coincidence说明第一空格的动词填入后应体现为是一种巧合,两个看不懂是什么的、只知道是不一样的东西(非相关专业的绝大部分学生是不太可能认识mitochondria和chloroplasts这两个词的)怎样了一个长的、可以认为是一模一样的DNA序列就是一个巧合呢?当然只有D的 share表示了这个意思。

A. contested.. provisional B. circumvented.. antiquated C. repealed.. vulnerable
