I'm probably wrong... but since no one answered this post yet i'm gonna guess... i don't remember much from eng AP...
Objective = as oppose to subjective... so this view is "unbias"
Narrative = as in narrator
put them together
A text (usually a story) told by a narrator who is unbias toward the situation... as if the person is sort of like a camera, showing everything, but not judging. An example of this could be a young child, looking at everything with a sense of innocence and so have no bias judgement on the other characters/events.
sorry, i could be wrong... lol
have you tried looking online?
