Would I get the point for outside source if I use an outside source that is related to the document. For example, if a document talks about the French Revolution but does not directly mention the French Revolution or one aspect of the French Revolution, could I mention this aspect and talk about how it impacted the document in order to get the outside source point?
Yes. You can expand upon something already in a document. For Example the life of a figure mentioned in a document.
I can’t say for certainty what the grader would give you, but if this document didn’t mention the French Revolution directly and you mentioned it, that sounds like it would be evidence outside of the docs!
