Q11:

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?

1. 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.

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

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

4. 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.

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

Answer : E

請教思路..謝謝

1. 从来没有因为广告而采购order的人中，大于三十五岁的人要比小于三十五岁的人多。可以堪称无关选项，never一词太极端，文中指的是last year，而且文中的比较都是给予in response to ad，而没有其他的比较，无关词也可以排除。
   
2. Among subscribers to Systems, the proportion who are under age thirty-five was considerably lower last year than it is now.在subscriber中，小于三十五岁的比例等等比较文中也没有说，排除。
3. Most merchandise orders placed in response to advertisements in Systems last year were placed by Systems
                   subscribers over age thirty-five.文中的most指的是people,而不是subscriber，所以也不对
   
4. 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.the average dollar amount无关词排除。
               
5. Last year many people who placed orders for merchandise in response to advertisements in Systems were not subscribers to the magazine.其实e选项也不是太好，因为many这个选项不好，多少是many呢，但这是best answer.我的解题思路是这样的。希望有帮助
