参考答案

正确答案：A
[答案]A。[解析] 该句凭借常识判断说法正确，因此答案可能是“正确”或“没提到”。借助题干中的 risks作为答案线索词，找到答案相关句：Donating a kidney means undergoing an operation that carries some risk．…So，what are the risks?…Even laparoscopy, a relatively new technique for kidney donation，is not risk-free. Doctors estimate that chances of dying from the procedure are about 3 in 10,000．该划线句尤其是在用数字表述死于肾脏移植的风险率，因此文章中涉及risks的句子所暗示的含义与问题句的说法一致。
