可以想成 diversity 的畫面是：你往一個群體裡看——一個班級、一片森林、一份歌單——發現裡面的東西不是同一種。那個「不都一樣」的性質，從外面看就是這個群體的一個特點。英文有兩種用法，看起來幾乎一樣：一種講那個性質本身（this school values diversity），一種講你實際看到的那一整片不同（a diversity of birds）。Two branches

range of differences · noun · C1
A range of people, things, or ideas that are very different from each other.
