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.
10（）
A.finding
B.uproar
C.complexity
D.puzzlement
参考答案：B
解析：
[试题考点] 上下文语意关系和名词词义辨析。
[解题思路] 本题空格是所在句主语的核心词，该句句意为“因此在公众中产生的______迫使Dr. Watson离开了实验室”。既然迫使他离开了实验室，那么公众的态度肯定是责备的、愤怒的，且根据前文中对Dr. Watson言论的评价和反驳也可推知，此番言论必定会引起公众的不满和反对，四个选项中，能表达这种感情色彩的只有选项[B]，uproar意为“骚乱；骚动”，代入文中，全句意为“由此在公众中产生的骚动迫使Dr. Watson离开了实验室”。
[干扰排除] 选项[A]finding意为“发现”，仅指实验的结果或者发现，不能表达群众对Dr. Watson言论的不满，与文章中对于Dr. Watson的否定态度不符。选项[C]complexity意为“复杂；复杂性”，代入文中意为“公众中的复杂性”，不符合文意。选项[D]puzzlement意为“迷惑；不解”，由第二段内容可知，群众对于Dr. Watson的观点并不是迷惑，而是普遍的反对，故选项[D]也与上下文不符。
