Norcross uses an analogy to try to persuade readers into believing what he has to say. Norcross is trying to prove that we should not eat factory raised meat. He uses a story of a man who tortures puppies in order to taste chocolate as his analogy. Fred, the man in Norcross’s story was in an accident and can no longer taste chocolate. He figures out if he tortures puppies he can get a substance called "cocoamone" that allows him to taste chocolate again. This is supposed to be similar to factory raised animals due to the torture that is inflicted upon them, but millions of people still eat those tortured animals.
