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、sponsored
B、recommended
C、criticized
D、supervised
答案D
解析 解答本题的要点是根据提示信息，推断需填入词的词意。本句中的关键信息是“one of them”，“them”指代上句中的“practitioners”(从业者)，由此可知Terrie Moffit也致力于研究智力和基因的关系。由此可推断出project。(项目)前填入的谓语动词应体现出Terrie Moffit参与到了项目中来研究智力和基因的关系。比较四个选项，D选项意为：指导项目，最充分地表明了参与项目，因此D选项为正确答案。
