I really like that you did further research into the claim and looked into the materials of the lawsuit in order to prove it. I also like that you provided the links to your articles and talked about how scientists did extensive testing and research to conclude that the "tuna" wasn't real. This provides credibility to the claim and helps provide accurate facts to back it up. NPR is also a typically reliable source for news and information, so I commend you for using that specific article as a way to support your answer. It is important for consumers to know what they are really eating, and companies can easily get away with things like this if not for research that people like scientists, and subsequently you, provide.
