问题     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 A、finding
B、uproar
C、complexity
D、puzzlement
答案B
解析 解答本题的要点是根据上文的大意推断出空格处词语的意思。本句中resulting修饰需填入的词，意为“因而发生的……”，可见本句填入的词要和上文中的关键信息“James Watson发表了不明智的、激进的言论”紧密衔接，即“因”在前句，“果”在空格处，由此可推断出：不明智的、激进的言论引起了骚乱，紧密衔接，符合语义。因此B选项为正确答案。
