Few scientific fields are as full of risk as that of research into human intelligence. The two questions that【1】over and over again are "is it a result of nature or nurture?" and "does race make a difference?"
Making【2】comments about the second question can be a【3】move, as James Watson, a co-discoverer of DNA structure, recently found. He suggested that he was "【4】about the prospect of Africa"【5】"all our social policies are based on the fact that their intelligence is the same as ours (white people) 【6】all the testing says not really". Such【7】are not merely【8】, they are scientifically weird. If the term race has any useful scientific meaning, then Africa, the continent where modern【9】began, is most racially diverse. The resulting【10】forced Dr Watson to leave his laboratory.
【11】, the study of【12】between intelligence and genetics has some wiser practitioners. One of them, Terrie Moffitt, of King’s College, has just【13】a project【14】the relative importance of nature and nurture. Dr Moffitt’s team【15】the effect on intelligence of breastfeeding, but in a genetic context. Previous studies have shown that breastfed children are more intelligent,【16】about six IQ points, than those given baby formulas.
The team, however,【17】the involvement of a gene called FADS2, which comes in two varieties, known as C and G. The researchers【18】if these two varieties【19】differently with breast milk.【20】on data two groups of people, they found that the intelligence increase associated with breastfeeding only happened to people having inherited at least one copy of the C variety. The effect did not depend on the social classes or IQs of the parents.
选项

B、whereas
C、since
D、as
答案
B
解析
本题的解题方法同题5,空格处需填入的是准确衔接前后句义的连词,空格前的句意为:目前所有政策的实施都是以他们和我们的智力水平相当为前提的;空格后的句意为:事实并非如此。由此可见,空格后的句子和空格前的句子是转折关系,B选项可以直接连接两个并列分句,且表示转折关系,因此正确答案为B选项。
