标题: 关于这道DS题的意义该如何理解(the larger number)

All 48 seniors in a certain high school take one of two English classes. What is the average (arithmetic mean) height of the seniors in this school?
(1) In the school, the average height of the seniors in the English class with the larger number of students is 70 inches.
(2) In the school, the average height of the seniors in the English class with the smaller number of students is (5/6) of the average height of the seniors in the other English class.

我选的是E,the larger/smaller number是什么意思,是不是48个里的大部分和48个里的小部分

指的是人数较多的班级和人数较少的班级吧，就是区分两个class用的

但题目中说All 48 seniors in a certain high school take one of two English classes.

one of two 应该是指2者之1啊意思是所有48个seniors学生在一个班里.怎么还会有一个smaller数量的seniors班呢
