I have run into a small question that I would like to check. When referring to one person out of a group, would one use "is" or "are"?
For example:
I know you are one of the members that is running things.
I know you are one of the members that are running things.
For singular "one" it should be "is", but for plural "members" it should be "are". I'm hitting a mental block here and I'm uncertain, so any clarification would be greatly appreciated.
