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] What is Yudell’s suggestion to scientists?
选项 A、They be more precise with the language they use.
B、They refrain from using politically sensitive terms.
C、They throw out irrelevant concepts in their research.
D、They examine all possible variables in their research.
答案 A
解析 事实细节题。定位句指出，亚戴尔说道，科学家们需要更具体的语言，或许可以使用像“血统”或“人群”这样的术语，它们也许能更准确地在个体和群体层面上反映出人类与其基因之间的关系。故答案为A)。
