单选题 The fact that he has made a serious mistake does not ______ your treating him that way.
A. justify B. prove C. verify D. agree

【正确答案】 A

【答案解析】justify意为“证明……正当”，指有充足的合法理由做某事；prove意为“证明”，指通过提示论据或证据来确立真实性或有效性；verify意为“证实”，指通过提供证据或证词来证明……的真相；agree意为“同意”，指对……意见一致。根据空格后面的treating him that way(以那种方式对待他)可知，应该选用justify。
