You are researching the similarities between the Star Wars and the Harry Potter sagas. You find a research paper on the web written on the same subject by graduate student at NYU. All of his sources are traceable. This source is: Extremely reliable Somewhat reliable Of questionable reliability Unreliable
I would say somewhat reliable since his sources check out but he is not a "professional"
His sources would not be considered extremely reliable considering he is not an expert in this field. Nor are they unreliable because his sources are credible. I don't believe it is "of questionable reliability," so your answer would most likely be B, "somewhat reliable."
