I'm taking an online course about conflict resolution and in one slide they show both forms.
First, there's this part where they show this web site: www.resolutionofconflict.com.au (it's unavailable now, maybe the course is really old). And then there's this image stating "Resolution of Conflict":
Then, after some seconds, they show this banner below stating "Conflict Resolution":
So, what's the proper way to state this phrase? I only knew that it should be the latter.
Also, is there any grammar rule to use for these cases?
