PREP cr-1-12

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?

(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.

我想问一下A为什么不对？

一般的must be true题型，是否一定要包含全文的信息？

即A,B两个人的对话，题干非针对其中的哪个人，那么回答必须包含2个人的内容？

这题答案选E

非常感谢！！！

原文说的只是last year的情况，A说的是who NEVER ordered merchandise...，看到never就不用再往下看了吧（如果整条时间轴是全集，原文说的只是全集里的一个子集，而A说的是整个全集。）

原题就是问，要原文所说的两个情况都是true，那么下面的哪个也一定要true

管他什么题型，人家问什么，你就答什么好了。

谢谢NN~~

事后仔细看发现的确是错了~~~~~

再问个问题，

如果把Never去掉的话该选项就对了吧？？

neo1001

去掉never也不对吧

去掉never的话，A和第一个finding说的就是同一回事咯，那始终和第二个finding连不上啊。

所以也就是说must be true一定要概括全文信息？

还是说，因为题干注明为：For both of the findings to be accurate？

neo1001

问题就是“For both of the findings to be accurate, which of the following must be true?”，就是要找一个东西，令到原文的两个findings都同时成立。问的就是这个，也不一定要说什么概括全文信息，只要令到原文说的都成立就可以了。

A的话，第一个finding是true，但是第二个finding不true啊。所以A达不到“令原文两个findings都true”这个要求，所以A错。
