The narrator.
The passage never gives the narrator a name, or refers to himself in any given name.
Typically when the narrator uses information that you could probably find somewhere trustworthy, like a textbook and goes on to give specific information that you would need to know for a unit or group of tests. For example, if the passage says "Christopher Columbus didn't actually mean to find the Americas, I guess you could say it was a happy mistake." That would be academic.
In some areas it does not rain for 9 years straight.
