@jhlaier so helpful!

@lizaloug97880 "Or" is used to create division between the two men in the sentence. You cannot have both Harry and Ron enrolled in Prof. Flit wick's Charms class. Because of this they should not be viewed as a unit- unless explicitly stated or supported by a referential. I would assume in other examples with multiple subjects they should be viewed the same way- solely.

@lesteryxue I also thought this.

@KilluhKatt it is what we are wanting to say about our subject.
