同意#9 这道题说的是 rate 和 number,# of reported illness = % of claiming ill * # of employee feeling sick
new policy实施前,% claiming ill很高因为没有医生去verify,真病与假病掺杂,%很高
new policy实施以后,% claiming ill应该是不变(也许都是真病)或者降低了(也许过去有很多谎称)
——总体来说,new policy是对 % of claiming ill造成影响,# of employee feeling sick却在argument中没有提及
当%降低,但# of reported illness仍然在增加时,就可以预料是 # of employee feeling sick在增加了
A - 对 % 和 # of employee feeling sick都没有造成影响
C - 正是在说 # of employee feeling sick在增加,因为更多人被传染
我觉得是这样的:
Before the policy, they might have taken the leave without going to the doctor, but now in order to take the leave they go to the doctor.
This does not direct us towards an increase in the number of people going to the doctor.
在政策前,某个人不看医生就请假,政策后,某个人为了请假去看医生了。但是政策前后都A的结果都是请假,所以整个公司的效率并没有说降低了。
我认为本道题最大的干扰选项就在于A,题目中已经说了,unless they were so sick that they had to go to a doctor ,这一点是作为题目的前提,CR推理过程有一大禁忌就是不能去否定给定前提,A 选项说more frequently went to the doctor,很明显根据新政策,不可能更频繁去医院
