In one of the activities to identify the various part of speech in the story, "The Paper Bag Princess", where the writer wrote that the only thing that was not burnt by the dragon was the princess paper bag. The word 'not' was identified as an adverb in the solution, while burnt was disapproved as being a verb, but rather an adjective or so. I don't agree with this. I think there's a mix up in the given solution. Please, the course instructor should look into this and correct the anomaly.
