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) by Dr. Watson are not merely (8) , they are scientifically weird. If the term (9) has any useful scientific meaning, then Africa, the continent where modern humanity began, is most racially diverse. The resulting (10) among the public forced Dr. Watson to leave his laboratory.
(11) , the study of the first question (12) between intelligence and genetics— has some wiser practitioners. One of them, Terrie Moffitt, of King’s College, has just (13) a project judging the relative importance of nature and nurture. Dr. Moffitt’s team (14) the effect on intelligence of breastfeeding, but in a genetic context. Previous studies have shown that breastfed children are more intelligent, (15) about six IQ points, than those given baby formulas.
The team, however, (16) the involvement of a gene called FADS2, which comes in two varieties, known as C and G. The researchers (17) if these two varieties interacted differently with breast milk. (18) on data from two groups of people, they found that the intelligence increase associated with breastfeeding only happened to people having (19) at least one copy of the C variety. The effect did not. (20) on the social classes or IQs of the parents.

C.Furthermore
D.Indeed
参考答案：A
解析：
[试题考点] 上下文逻辑关系和副词用法辨析。
[解题思路] 本题空格位于第三段段首，空格后的内容意为“对第一个问题的研究有更加明智的实践者”，而上一段的内容说明了关于种族以及智商之间的研究出现了不令人满意的研究者，由此可知空格前后的内容形成了对比，选项[A]fortunately意为“幸运地；幸好”，前面经常是不太好的情况，而后面常跟比较好的情况，代入文中，符合文意，故该选项正确。
[干扰排除] 选项[B]particularly意为“特别；尤其”，多用于表示强调或者特别说明，选项[C]furthermore意为“此外；而且”，表示递进关系，选项[D]indeed意为“确实；的确”，用于强调或确认已经提到的事实，这三项都无法表示文章中前后对比的逻辑关系，故排除。
