参考答案

正确答案：B
[答案]B。[解析] 借助常识判断该句的说法不合理，所以可以直接判断“错误”。如果借助原文， 利用题干中出现的“reasons，better off，with one kidney instead of two”作为答案线索，这样发现答案相关句： You could argue that you may be helping to save a life，but you certainly can't pretend that you're better off with one kidney instead of two．该句说“你不能假称有一只肾脏比有两只肾肚更好”，显然该句的说法与问题句的说法不一致。
