Dr. X claims that she has found a new remedy (carrot extract) to cure acne. She scores an interview with the science writer for a local newspaper, and gets a brief article written about her and her claims in that newspaper. The article does not contain any experimental evidence, but mentions that Dr. X accidentally splashed some carrot extract on her face and found that the acne was reduced a few days later. Student Y finds the article and cites it as a source for a paper he is writing for class, as evidence that acne has been cured. (a) Is this finding a fact, a theory, a hypothesis, or an observation? Explain why you think so. (b) Was it OK for Student Y to use the newspaper article as evidence for his paper? Explain why or why not.
