一道归纳题
Finding of a survey of Systems magazine subscribers: Thirty percent of all merchandise orders placed by subscribers in response to advertisements in the magazine last year were placed by subscribers under age thirty-five.Finding of a survey of advertisers in Systems magazine: Most of the merchandise orders placed in response to advertisements in Systems last year were placed by people under age thirty-five.
For both of the findings to be accurate, which of the following must be true?
Which of the following would be most important to in order to evaluate the argument?"
A. More subscribers to Systems who have never ordered merchandise in response to advertisements in the magazine are age thirty-five or over than are under age thirty-five.
B. Among subscribers to Systems, the proportion who are under age thirty-five was considerably lower last year than it is now.
C. Most merchandise orders placed in response to advertisements in Systems last year were placed by Systems subscribers over age thirty-five.
D. Last year, the average dollar amount of merchandise orders placed was less for subscribers under age thirty-five than for those age thirty-five or over.
E. Last year many people who placed orders for merchandise in response to advertisements in Systems were not subscribers to the magazine.
答案是E选
------------------------------------------------------------------------------------------------------------------------
我这么想的:
1. 第一个survey提到的是全部的订阅者订单和35岁以下订阅者的订单;(all of whom are subscribers )
2. 第二个survey提到的则是全部的订单和35岁以下的人下的订单。( all of whom are buyers including subscribers and non-subscribers)
显然,全部的subscribers 所下的定单数要小于全部的buyers下的订单数,因为还有很多数量未知的non-subsrcibers也看了广告,并下了单。
比如: ①借阅朋友的Systems杂志,看到广告而下单的non subscribers
②在航班上读了飞机上赠约的Systems杂志的non subscribers
③在报刊亭翻阅了Systems杂志却没有买的non subscribers
等等这些情况都是没有订阅杂志,而却可以因为看到广告而下单的buyers
E 选的意思是【很多看到广告而下单的用户并不是杂志的订阅者】,措辞还不是Most,而是Many
那文章的那些数据根本不需要看啊,直接秒选E啊
因为有non subscribers的存在,就意味着肯定有非订阅者下单啊,文章E选也没说是most是非订阅者,那只要有一点点也算many了,数据都不用看了,直接E。
是我脑洞开太大还是这题有毛病?
