昨天一位朋友提供了一道所谓的真题，请大家讨论一下答案

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?

--------------------------------------------------------------------------------

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.

Among subscribers to Systems, the proportion who are under age thirty-five was considerably lower last year than it is now.

Most merchandise orders placed in response to advertisements in Systems last year were placed by Systems subscribers over age thirty-five.

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.

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

这道题我读了若干遍，到现在连题干还没有完全搞明白，更别说选项了，555555

这个题实际上主要是解释两者的差距：

（1）Most of the merchandise orders （等于大于50%）

（2）Thirty percent of all merchandise orders

虽然我开始题干也看得似懂非懂，但是，还是决定选E.然后仔细想了，E应该是对的。

这道题好像在哪里见过。

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.

对Systems杂志的订阅者的调查发现：30%对该杂志上广告有反应（既买这些广告商产品）的是35岁以下的。 （既70%的买登载在该杂志上广告商产品的人是35岁以上的，但是要注意的是偶们并不知道这70%的人是看了这个杂志以后呢，还是没看，而从其他渠道知道这些产品的）

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.

对在S杂志上刊登广告的广告商的调查：看了S杂志广告后购买这些广告商产品的人大多数是35岁以下的人。

上面所述都正确地话，既说明那些35岁以上的购买产品的人都是从其他渠道，也就是说不是通过看Systems杂志后买产品的。所以就是E.不知道有没有解释清楚...请指教
