5 between most of如何理解（来自2021高考英语全国卷I阅读理解D）
下面的内容摘自2021高考英语全国卷I阅读理解D，请问其中的between most of 如何理解？不是说 between 要用于两者之间吗？这里为什么用于 most of 之前？
The researchers examined various levels of noise on participants as they completed tests of creative thinking. They were randomly divided into four groups and exposed to various noise levels in the background, from total silence to 50 decibels (分贝), 70 decibels, and 85 decibels. The differences between most of the groups were statistically insignificant; however, the participants in the 70 decibels group—those exposed to a level of noise similar to background chatter in a coffee shop-significantly outperformed the other groups. Since the effects were small, this may suggest that our creative thinking does not differ that much in response to total silence and 85 decibels of background noise.

between 除表示在两者之间外，还可表示在多者中的“每两者之间”。如：
I never eat anything between meals. 我在三顿饭之间不吃任何东西。
There’s no continuity between the three parts of the book. 这本书的三个部分之间彼此没有连贯性。
He worked hard to improve the relations between the three countrie. 他努力工作以改善三国之间的关系。
2021高考英语全国卷I阅读理解D中的这个句子中的 between 也属于这个用法，它表示“多个组中的每两组之间”。
The differences between most of the groups were statistically insignificant.
意思是：多数组彼此之间在统计上的差别并不明显。
