还是阅读理解问题呀，

1.“30% of all merchandise orders placed by subscribers”把我搞死了。应该是订阅者订单的30%，而本人却总在30%的订阅者的提出订单里打转（英文是：orders distributed by 30% of subscribers)。

2. subscribers under age 35 和 people under age 35概念不同 

3.如此下来把两句话简化一下，就是：35岁以下的订阅者，占订阅者订单的30%。（注意，订阅者订单属于订单来源的一部分）。而35岁以下的人是订单的主要大部分来源。

所以递推出：很多订单来自（35岁以上的）非订阅者。

画一个集合图，可能比较好理解。跟数学题一样了，晕呀。

晕死了，今天做这个题。我也来贡献一点吧：

(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.没有讨论没有发布订单的订阅者这群人！！这个是无关项。
(B) Among subscribers to Systems, the proportion who are under age thirty-five was considerably lower last year than it is now.无关的时间点
(C) Most merchandise orders placed in response to advertisements in Systems last year were placed by Systems subscribers over age thirty-five.绝大多数的订单是由大于35岁的订阅者发出的，这个与条件2矛盾
(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.与钱数无关
(E) Last year many people who placed orders for merchandise in response to advertisements in Systems were not subscribers to the magazine.正解～

首先应该找差别，第一个是订阅杂志然后按广告订购的人的比例，第二个只是看广告订购的人。

这题我也做错了. 借机理一理思路.

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.

意思是说: 订杂志者且回应广告的人里面, 有30%是35岁以下的.

 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. 回应广告的大部分人是35岁以下的.

 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. 回应广告的大部分人是35岁以下的.

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. 我就错选了这个. A是说, 订了杂志且没有回应广告的人里面, 超过35岁的人比低于35岁的人要多. 原文是在讲订杂志且回应广告的人, 按XDF老师的说法, A项改变了"论域", 属于无关选项.

(B) Among subscribers to Systems, the proportion who are under age thirty-five was considerably lower last year than it is now. 原文只讲了去年, 没讲今年. 时域改变, 错.

(C) Most merchandise orders placed in response to advertisements in Systems last year were placed by Systems subscribers over age thirty-five. 原文没有对应的内容支持.

(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. 原文只说了订杂志且回应广告的人里, 小于35岁的占小部分(30%). 但是没有讲到订单的金额问题.

(E) Last year many people who placed orders for merchandise in response to advertisements in Systems were not subscribers to the magazine.

rationalusa 解释的比较清楚了

楼主在看题名时务必要当心鬼子的陷阱：

订单分两类：1.订阅者定的 2.非订阅者定的

条件1说的是：1.35%的由订阅者定出的订单是由35岁以下的订阅者做出的

条件2说的是：1+2（即全部订单）的绝大部分都是由35岁以下的人定的

那么第一：所有的订单不可能全来自于订阅者，否则条件2不成立

如果订单分两类成立，条件1不满足条件2的话，只有一个可能性：条件1是条件2的极小的组成部分，即E

版主不愧为为版主啊！

条件一说：A/C=30%
条件二说：（A+B）/（C+D）=MOST

答案是：D/（C+D）=many
