我觉得答案是A
我用的是排除法！
B答案明显不对，因为原文压根没有提到现在的情况！
C与原文所提内容相反！
D原文没有提到钱的事，也无从知道人均花费，是under age thirty-five 多还是over age thirty-five多！
E：原文也没有提到订购商品是否订购magazine.

但是A为什么对，我也不是很清楚，我只是觉得通过排除法，可能A更合理！

请各位多指点！不知道我分析的有没有道理？

5.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?

题目不完整！如上所述——

我自己这么理解的：
Finding of a survey of Systems magazine subscribers
这个survey的调查对象是subscribers

而Finding of a survey of advertisers in Systems magazine
而这个survey的调查对象是所有订购 the merchandise orders的人！

明显前一个survey的人只是后面这个survey的一个子集！
所以我觉得选E是合理的！

八戒说的有理，因为两个描述乍一看中间有矛盾的，一是大多数的订购来自35岁以下，一是订阅者中订购的35岁以下的只是少数，画图就很简单了。

题干有错吧？
既然说both of the findings
为什么只有一个conclusion？

答案是e
画图是最好的办法

以下是引用cognito在2003-10-18 10:11:00的发言：

八戒补充了
我觉得应该是e吧？
