问题 In the beginning of paragraph one we are told that scientists can not agree______.
A gene for chopsticks flexibility is found to be______.
选项 A、unrelated to the ability to use chopsticks
B、related to the ability to use chopsticks
C、unrelated to the ability to use forks
D、related to the ability to use forks
答案A
解析 发现A和B，C和D正好是一正一反，问题句问及“使用筷子的适应性”，利用这个词作为答案线索，这样发现答案相关句：One is the possibility that Plomin’s group fell for“chopsticks fallacy”． Geneticists might think they’ve found a gene for chopsticks flexibility，but all they’ve really found is a gene more common in Asians than，say，Africans．前一个句子已经提到“对筷子(认识的)谬误”。后面的一个句子说“遗传学家可能认为他们找到了与筷子适应性相关的基因，但实际上他们所发现的只是在亚洲人身上常见的基因，而这种基因在比如非洲人身卜较少见”。因此判断A是答案。
