刚开始学啊

字太多，怎么上传图片啊…
Over the past decade, many companies have begun using automated telephone services: callers hear a machine-generated voice and are able to select options using the numbers on the telephone keyboard. Research shows that callers are more patient when the machine-generated voice is that of a woman. Thus smaller companies that cannot afford an automated service should consider hiring women, rather than men, to interact with customers by phone.
Q: Which of the following , if true, would be most damaging to the conclusion above?
答案选下面这个，可是我一点都不理解…
A separated study indicated that the extra patience exhibited by callers is limited to interactions with an automated system.

类比推理找削弱

Event A: callers are more patient when the machine-generated voice is that of a woman
Event B:  smaller companies that cannot afford an automated service should consider hiring women, rather than men, to interact with customers by phone.

从人们对女性声音的自动应答机更有耐心，推导出“用不起自动应答机的小公司应该雇佣女性接线员（顾客会更有耐心）”

削弱的方向：Event A和Event B有不同点：automated service 和 人工服务 真的一样吗？
答案一定同时包括Event A和Event B，指出他们的不同点。
A.separated study indicated that the extra patience exhibited by callers is limited to interactions with an automated system. 指出了automated service 和 人工服务的“不同”：人们在自动应答机的时候更有耐心。所以，即使小公司请波多野吉衣来接电话，顾客该不耐烦还是会不耐烦。

捱喽儿

如果对机器自动回答的耐心指数是50，而对人的都是100以上，那么究竟hire 男还是女是无法确定的；
