The function of genetic testing is
A．to enable people to change genes.
B．to help people to create good genes.
C．to predict diseases people may have.
D．to detect accurately what diseases people may develop.请帮忙给出正确答案和分析，谢谢！
参考答案
正确答案：C
解析：事实细节题。由题干关键词genetic testing将信息定位于第二段首句。从定语从句which makes it possible to find dangerous genes可知，基因测试的目的是为了找到人类所拥有的危险基因，故[C]正确。[A]、[B]可以较容易排除；[D]“准确检测出人们可能得的病”，与文章所谈到的基因是否会引发疾病还取决于环境等其他因素相悖，故不选。
