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.
7（）
A.policies
B.tests
C.remarks
D.questions
参考答案：C
解析：
[试题考点] 上下文语意关系和名词词义辨析。
[解题思路] 本题空格所在部分为句子主语，该句句意为“这些______不仅仅______，从科学上讲也是不合情理的”。显然，该句是作者对上文中Dr. Watson的观点做出的评价，主语such______即指代上文中Dr. Watson所说的话，四个选项中符合这个意思的只有选项[C]remarks(评论，谈论；话语)。
[干扰排除] 选项[A]policies意为“政策；方针”，选项[B]tests意为“试验；测试”，选项[D]questions意为“问题”，很显然，Dr. Watson的言论既不是“政策”，也不是“测试”或者“问题”。故可排除这三项。
