5 he, however, might tremble at the 6 of what he is about to do.Together with another two scientists, he is publishing a paper which not only 7 that one group of humanity is more intelligent than the others, but explains the process that has brought this about.The group in 8 are a particular people originated from central Europe.The process is natural selection.
This group generally do well in IQ test, 9 12-15 points above the 10 value of 100, and have contributed 11 to the intellectual and cultural life of the West, as the 12 of their elites, including several world-renowned scientists, 13.They also suffer more often than most people from a number of nasty genetic diseases, such as breast cancer.These facts, 14, have previously been thought unrelated.The former has been 15 to social effects, such as a strong tradition of 16 education.The latter was seen as a (an) 17 of genetic isolation.Dr.Cochran suggests that the intelligence and diseases are intimately 18.His argument is that the unusual history of these people has 19 them to unique evolutionary pressures that have resulted in this 20 state of affairs.

参考答案: B
参考解析: 该空的前后语境为“有些群体的人可能比其他群体更加聪明,这是人们一直不敢明说的假说之一。但是,不管怎么样,Gregory Cochran 说出来”。显然,从语义上应该可以看出Gregory Cochran表述这一观点是一种主动行为,从而排除A和C;而从第一句可以看出他所研究的这一课题也不应该是一个让人高兴的主题,故排除D。因此答案只有B。
