Okay so an appropriate article would be a reliable one. - A reliable source will have other websites cited, or it will be a well known place like a scientific magazine, government websites, or Newspaper. An appropriate article will also have at least 3 points you can use in your writing. Even if they are small things. Also if the sight is using formal writing, by someone who knows what they are talking about. (again like a scientific magazine written by a biologist) This means websites like "Answers" or "Yahoo answers" are not appropriate or reliable.
