问题     More than 100 years ago, American sociologist W. E. B. Du Bois was concerned that race was being used as a biological explanation for what he understood to be social and cultural differences between different populations of people. He spoke out against the idea of "white" and "black" as distinct groups, claiming that these distinctions ignored the scope of human diversity.
    Science would favor Du Bois. Today, the mainstream belief among scientists is that race is a social construct without biological meaning. In an article published in the journal Science, four scholars say racial categories need to be phased out.
    "Essentially, I could not agree more with the authors," said Svante Paabo, a biologist and director of the Max Planck Institute for Evolutionary Anthropology in Germany. In one example that demonstrated genetic differences were not fixed along racial lines, the full genomes(基因组)of James Watson and Craig Venter, two famous American scientists of European ancestry, were compared to that of a Korean scientist, Seong-Jin Kim. It turned out that Watson and Venter shared fewer variations in their genetic sequences than they each shared with Kim.
    Michael Yudell, a professor of public health at Drexel University in Philadelphia, said that modern genetics research is operating in a paradox: on the one hand, race is understood to be a useful tool to illuminate human genetic diversity, but on the other hand, race is also understood to be a poorly defined marker of that diversity.
    Assumptions about genetic differences between people of different races could be particularly dangerous in a medical setting. " If you make clinical predictions based on somebody’s race, you’re going to be wrong a good chunk of the time," Yudell told Live Science. In the paper, he and his colleagues used the example of cystic fibrosis, which is underdiagnosed in people of African ancestry because it is thought of as a "white" disease.
    So what other variables could be used if the racial concept is thrown out? Yudell said scientists need to get more specific with their language, perhaps using terms like "ancestry" or "population" that might more precisely reflect the relationship between humans and their genes, on both the individual and population level. The researchers also acknowledged that there are a few areas where race as a construct might still be useful in scientific research: as a political and social, but not biological, variable.
    " While we argue phasing out racial terminology(术语)in the biological sciences, we also acknowledge that using race as a political or social category to study racism, although filled with lots of challenges, remains necessary given our need to understand how structural inequities and discrimination produce health disparities(差异)between groups. " Yudell said. [br] The example of the disease cystic fibrosis underdiagnosed in people of African ancestry demonstrates that______.
选项 A、it is absolutely necessary to put race aside in making diagnosis
B、it is important to include social variables in genetics research
C、racial categories for genetic diversity could lead to wrong clinical predictions
D、discrimination against black people may cause negligence in clinical treatment
答案 C
解析 推理判断题。定位句的第一句指出，亚戴尔认为如果临床预测是基于病人的种族做出的，那么大部分时候结果都是错的，紧接着在下一句里亚戴尔举出囊性纤维化的例子，该疾病被认为是“白种人”的疾病，因此很容易在非裔人身上漏诊，由此可以推出，亚戴尔以囊性纤维化为例是想说明上一句话里的观点，即对遗传多样性进行种族分类可能导致错误的临床预测，故答案为C)。
