1.subscribers 来看, subscribers 下的定单里面只有30%是35岁以下的人
2.total 来看, 大多数定单是35岁以下的人下的.
从1,2可以得出'下定单的人里面很多不是subscribers ', 是E

前一项调查杂志的订阅者表明：去年由订阅者发出的order要求中，30%是小于35岁的人。而后一项研究却表明：大多数的order要求都是来自小于35岁的人的。发现了没有比例虽然不同，但是后面的范围也是不同的，前项调查是订阅者订单的比例，后者是订单的比例，于是这道题的逻辑着眼点是是否是订阅者。答案就给了明确的解释，这些订单中有很多是第一次来定的，不是平时的订阅者。
